1.1. Definition and Overview of Pica

Pica is a condition in which dogs exhibit the behavior of ingesting non-nutritive substances such as rocks, fabric, dirt, or soil. The material to be eaten may be chewed, crushed, and then swallowed. The time and frequency of the intake may vary, but it is a repetitive movement that a pet performs regularly, making it as much obsessive-compulsive.

Some of the possible causes of pica in dogs are that they have a gastric upset. Dogs consume grasses mixed with mucus or bile to cure upset stomachs by prompting vomiting. Animals with anorexia also need consumption to stimulate gastric secretion. In dogs with a more or from their anorexia, there can be a psychological component to their consumption. The desire to consume may be linked to hunger. Pregnant women and/or lactating dogs may be deficient in some minerals (iron, calcium) and may develop an interest in non-nutritive materials to fill these deficiencies. In addition, there is some evidence that pica may develop when food is unpredictable (especially for pig hunting dogs). It may also be related to social status, and although rare in dogs in general, it is common in dominant bitches.

The main problem caused by pica consumption in dogs is obstruction of the stomach or bowel leading to death. Therefore, the key to controlling the design is precluding access to the goods consumed. With a high nutritional value, limit the hidden "high value" access that the dog has to the items of its choice, and keep stimulating toys and games available to the dog when you want to play or chew. Owners should also be aware of the symptoms of pica in humans, such as chronic fatigue and diarrhea, constipation, soreness, and/or rectal bleeding if food is not diagnosed properly for a long time. However, some of the treatments for depression are antidepressants, and some of these medications have anti-anxiety drugs and anxiolytic drugs that can be used to treat obsessive-compulsive chewing disorders.

2. Causes of Pica in Dogs

Regardless of the breed, pica in dogs develops as a result of either some nutritional deficiency or psychological cravings. This behavior can also be a result of some internal deficiencies too. In the case of excessive hunger, dogs may abruptly start eating whatever they find in their surroundings. Their choices can be motivated by the urgent requirement of something found in that particular object. A dog eating dust may be in need of roughage, so eating the dirt and dust will add fiber to their diet. Such dogs may also eat grass. Dogs that eat paper and fabric may have dietary shortages of sweet-flavored carbohydrates, hormone development, medical pica as well as sugar through natural fermented means. The same can happen with sweet and flavored edibles like crackers and sweet cookies. Malnutrition can also encourage an atypical diet. Dogs that are bored and left to their own devices become curious and start playing with small items in their surroundings. Over time, this curiosity turns into eating random items.Dogs rely on chewing to control chronic anxiety that doesn’t go away. The urge to chew has no age preference. 68% of dogs on medication and 56% of dogs off medication engage in inappropriate chewing because they have access to inaccurate causal data. "Environmental or conditioned reasons may bring off the wall chewing. You need to ask what condition in the environment there is when a dog prefers a shoe to a bone," says Concha-Cory. "What's wrong in the human-animal bond? It's a puzzle people and a puzzle dogs don't see."

2.1. Nutritional Deficiencies

Pica can appear from a variety of causes in dogs, but it usually involves undesirable behaviors. In dogs, pica is characterized by a love of consuming (or wanting to consume) items that cannot be thought of as food. Natural soil, sand, twigs, feces, stones, baby attire, wool blankets, butterfly cocoons, cat feces, and horse manure have been consumed by our canine buddies. Every day, new clients who have schedules undone by their pet's behavior wander into clinics. Occasionally, clients clear jam-packed foreign bodies through their dog's stomach and truly wonder. As fellow creatures, they ask us to find out and identify the causes and treatments for their pet's serious medical condition.Nutritional deficiencies are often considered to be associated with pica in dogs, as it is thought to be more common in underfed dogs. Many speculate that increased hunger from small intestinal problems, such as exocrine pancreatic insufficiency, inflammatory bowel disease, or intestinal lymphosarcoma, leads the dogs to explore (smell and maybe nibble at) the environment in seeking of something palatable or healthy to eat. Observational paper noted that a Border Terrier dog with inflammatory bowel disease that involved a narrow range of alimentary components (duck and rice) and hypovitaminosis A diagnosed with a coin foreign body. Pica in this pet was felt to have altered the threshold for this individual to eat the uncharacteristic object. The pet was on a single protein diet and did not experience prior pica during its relationship with potato.

2.2. The Behavioral Causes

It is vital to differentiate Pica from other compulsive disorders such as Coprophagia, the consumption of encopretic material or feces, or Olifacio, the consumption of offensive odors such as stool from other animals. While these disorders may be longstanding, they may also be due to an underlying medical or psychological disorder or even boredom. While the jury is still out on whether Coprophagia should be considered normal, a form of survival mechanism, or therapeutic intervention of dogs, it remains psychologically unsatisfactory and disagreeable to their owners. One study found a strong impact of internal motivations such as breed and male dogs as well as lower social status at home relative to owners attribute to the disorder that would differ from a reward system basis (with better feeding and attention relative to deprived animals).Some of the most prevalent reasons for pica and odd feedings are anxiety, boredom, a need for attention, and lack of meat. Pica can also develop as a sign of dominance or an attention-getting mechanism. In two mild cases of licking stones and the floor, the dog also had a sibling for stimulation and companionship while another report noted the same excessive behavior in two littermates. Obesity, age, outdoor environment, and chronic illness have been offered as statistically supported opposing characteristics of dogs with the disorder, but none of these studies control for breed similar to the case of Coprophagia's preponderance of males. Unfortunately, as they reside often outdoor or in a confined house, Pica dogs often also live a life of neglect and abandonment.

3. Symptoms of Pica in Dogs

If your dog is showing strange dietary habits, they may have a condition known as pica. Pica is when animals will eat things that they are not supposed to eat. This can be as strange as eating rocks or plants, to eating feces or its own vomit. Pica can be cultural as well, and increase if an animal has puppies. There are several possible causes for pica. These include emotional factors such as stress or loneliness. Owners with pica do not mean their pets are being neglected or poorly cared for in any way. If you notice any of these symptoms in your dog, seek veterinary care to deal with dietary problems.

Symptoms of pica include behavioral signs such as weight loss, poor appetite, and even the dog refusing to eat at all. This is partially due to its poor diet and potentially upset stomach. This will also damage the teeth of the dog if they are eating rocks or metal staples of any variety. Other symptoms can be caused by the objects consumed. Rocks, plants especially those that thrive in the home can be poisonous, and any foreign objects can obstruct the digestive system. This causes pain, and the dog might take a strange position to try to relieve this pressure, such as walking hunched over. This can also cause vomiting. The owner might see the dog eating an object they should not consume outside of their weird diet habits. Busying the dog indoors if they have a habit like eating feces can also result in the dog vomiting up its dinner or marking.Pica is often observed in very young dogs, age six to nine months, though it can affect dogs of any age. This behavior is considered development in young dogs, but it may become a habit and is a likely signal of underlying anxiety if the behavior persists longer than it should.

3.1. Behavioral Signs

Three distinct categories of signs exist that can help in identifying dogs affected by pica. Behavioral signs include eating items that are not considered palatable, a preference for consuming certain types of substances over others, and consumption of unusual objects that would not generally be considered food. The dog may exhibit these signs in the absence of hunger or lack of access to a normal diet and may even continue to eat the unusual substances if their intake is associated with any adverse effects. Medical signs may include symptoms such as the presence of food inedible to the species normally found within the stomach, regurgitation of consumed items, gastric dilatation or volvulus, and possible signs such as weight loss, vomiting, constipation, or other signs of gastrointestinal obstruction.

Barium radiographs or an exploratory laparotomy procedure must be conducted to facilitate the examination. Diagnostic signs may also include any concurrent diseases like hypothyroidism, severe hepatic function, lead poisoning, or ataxia, resulting in the abnormal behavior of ingesting unusual substances. Lithium therapy, low palatability, or other factors of contaminants that dogs might ingest inside or outside the home may also lead to consumer attraction. However, because these signs are unreliable indicators, they are not linked to general motivational (i.e., appetitive) behavior and may not be identified as the best criteria for diagnosing pica.

3.2. Physical Signs

Dogs are generally loving and obedient animals. They will often do almost anything they can to receive praise from their owners. But to those who only want to be pampered by their owners, Pica is a step too far. Puppies tend to chew or "taste" objects as a form of investigation, but must be trained to stop this behavior as soon as possible. Otherwise, it may develop into Pica, which can result in expensive furniture being chewed, objects being destroyed, or worse, and health suffering. If a dog continues to eat these substances for more than a month, you will need to develop a plan to change its way of thinking. There are many medications that can help with this condition. As many of the symptoms are similar to those of other conditions, it is important to have a vet examine the dog to ensure that Pica is the real problem. Use this aid to learn more about the possible problems.

The development of this disorder is best prevented through good husbandry, which includes feeding a balanced diet and providing appropriate toys that add mental stimulation to the dog's life. This also helps to redirect the dog's energy and desire to chew and pull items towards something less harmful. This also goes for dogs which have already been diagnosed with Pica, who should have the objects they need to chew, such as rawhide, which has been proven to help. If the dog simply cannot be trained in different ways to deal with the condition, medication is available. This is not a cure, but is used to lessen symptoms and make the dog easier to control.

4. Diagnosis and Prevention of Pica in Dogs

When dogs compulsively consume things that are not food, they can exhibit pica. Additionally, strange things might cause intestinal complications. Veterinary assessment and diagnostics can usually detect the issue causing pica and contribute to solving the concern. Several neurotransmitter plaque drugs or calorie shortages could cause dogs to have pica behaviors. Genes and discrepancies cause pica behaviors in other dogs. Smart chewing is a trait of some dogs, and it is part of their nature. The deficiency of supplies in the household may also entice dogs to consume extra materials that are not food.

Handling pica is a complex process that necessitates strategies to eliminate from the diet or discourage abnormal appetite for eating a strange substance. Apart from stopping the behavior with professional guidance, other preventative steps to reduce the possibility of pica growth are hard work, time, and patience. There are fewer things that can be done to prevent dogs from consuming nonfood sources. The only standard approach to avoiding pica in dogs is to guarantee that the dog is well fed and supervised. Clean the rubbish bin after consuming something, wood (especially treated), and paper/burned things. It is necessary to make decisions about what cleaning products are present. Also, the cage or kennel should be cleaned up. Dog-owning parents must choose their own meals and watch what their pets are eating. A dog will eat or chew itself, fabric toys, socks, underwear, towels, linens, papers, hair, couch stuffing, rubber objects, parchment sticks, greenery, grass, and garbage after smelling the materials or substance if they are not fed.

4.1. Veterinary Evaluation

Just as with any medical condition, Pica can have serious, potentially life-threatening consequences for dogs. Veterinary evaluation is an important step in ruling out an obvious inciting cause (e.g., anemia or malnutrition). Beyond performing a thorough physical examination and basic laboratory tests, choosing the appropriate advanced diagnostic testing depends on the veterinarian's assessment of the dog's history and clinical signs. They may consider additional tests to identify a potential underlying medical condition, metabolic disturbance, gastrointestinal disorder, or toxicosis.

Pica is not typically a primary diagnosis for which a dog presents to a veterinarian. Instead, a dog may present for examination because it is displaying clinical signs that its owner perceives as resulting from consuming inappropriate items. A complete veterinary assessment is important to rule out linked conditions and to differentiate between behavioral problems that may require treatment or therapy. If the dog has a medical condition that has resulted from its ingestion of inedible objects and "serves as a model for extraneous behavior," then behavioral therapy may not be beneficial unless the medical condition is resolved. In some cases, there is a true emotional conflict for a dog in a specific context, and the objects it consumes then serve an emotional purpose. In most cases, however, the dog has a general need to provide itself with oral satisfaction and stimulation.

4.2. Preventive Measures

Dog owners must make sure the dog's environment is safe, non-toxic, and free from small objects the dog might be tempted to eat. A chewing dog might do well with a rubber toy containing a snack, which might help him or her to focus the cravings on legal eating adventures. Play with a ball by dribbling it and consuming short time outs of the exercise might stimulate an anxious dog to do something else rather than force him or her to crave the earth in the absence of stimuli. A new object might be introduced, offered in the place of the one craved or can even be offered in case of a truce offering.

Dogs should not remain unsupervised to truly make sure the real cause is behavioral origins. When the behavior is established and the cause determined, the owners can then modify their strategy to meet the dog's actions. It has been said that coprophagia may be an attempt to hide incidences of extreme aggression, and can be a gateway towards other abnormal behaviors. This is especially important when the reason behind behavior is due to emotional distress. In the case of punishment, the initial behavior is not the one being punished, but the level of distress. Treatment or prevention of abnormal behavior should therefore also cope with the underlying reasons, not just the end result.

5. Treatment Options for Pica in Dogs

For dogs that are being treated for pica, you, as the pet owner, must maintain constant supervision and stop them whenever they start to chew on things that they should not be. This takes time, patience, and dedication, but it is essential in preventing pica from turning into a very hazardous situation for your dogs. If your dog likes to chew on things, offer them some safe items that they can chew on throughout the day. These are fine to chew on, and they also help to keep their teeth and gums clean and healthy. Pica is an eating disorder and an undeniable hunger for eating things that are not food. Because excess consumption is covered below, the behavior can be difficult to treat if the underlying issue is not addressed. Any form of treatment involves termination of the outlet for eating in order to replace it with food.

• Behavior and training: Behaviorally treat pica disorder with positive reinforcement training. Enforced timeouts and changing the environment may be useful in some cases. Some improvement in pica may be possible with persistence and training. Avoid punishment as a training technique, as it can uncover an irrepressible disgruntlement. Toys may also be useful in redirecting the dog’s focus. Cob theory also suggests that feeding the dog smaller meals or increasing the fiber content in the bulk of the food would help. It also suggests that when addressing the behavior and pica in a dog when they are caught chewing or swallowing, it is important to determine whether it is a learned behavior. Try not to alienate the dog. Given that it is a coping mechanism, separate feeds will help to single out if this problem is learned behavior from the environment and/or dog, as opposed to a medical issue.

5.1. Behavioral Modification Techniques

Behavioral modification can be used to help pets seek alternative behavior to the pica behaviors. This is usually more effective if the owner addresses the pet with the problem as a puppy. Learning through toys is often mistakenly or subconsciously discouraged. Owners need to ensure this does not happen.

The pet with pica is not a pet that can be left to find their own form of entertainment. Owners need to select toys that are safe, indestructible, and too big for the pet or any pieces to pass through their gastrointestinal tract if the pet does manage to destroy them. Owners should also select toys that are free of chemicals, dangerous products, and are the "appropriate" size for the pet. This will minimize the chances of the pet ingesting parts of the toy. Toys that can be filled with treats so the pet can nudge them and have food dispensed are also ideal. Toys need to be rotated weekly so they remain stimulating and interesting. Offering alternate toys such as cat toys, chasing toys, soft toys, and items to rip up, break, or crunch are also ideal. Owners can also develop their own games for pets to utilize, for example, an ice cube with a squishy food inside it, or a soft honey-filled Kong you can change the food stuffing. Your writing can be more formal, for example, based on a report or analysis, or more informal, for example, based on an article or blog post citing journal articles and studies and the reasoning behind using certain testing.

5.2. Dietary Changes

In some suspected medical cases, your veterinarian may recommend a dietary change. Abnormal eating behavior can be caused by dietary imbalances, nutritional needs not being met, and lack of essential vitamins and minerals. Thus, adding these nutrients may reduce the animal's desire to consume non-nutritive materials. With nothing to consume, the animal may also become less focused on eating non-food items. Furthermore, colon disorders may lead to coprophagy as dogs consume their feces in an effort to regain unabsorbed nutrients. A bland diet or high-fiber diet may fix or help mitigate these defects, such as affecting tissues and mucus surrounding the feces secondary to physiologic responses to acute diarrhea. Fiber also increases fecal volume, which can help coprophagous dogs to be satisfied or deter coprophagy by making stool less appealing.

Fiber-rich diets are often used to alleviate choking, diarrhea, and constipation, suggesting that it might also aid in the treatment of pica by managing these medical circumstances. One method focuses on feeding alternative foods such as more raw foods, but the optimal nutrition (homemade, commercial, etc.) remains contentious. Be conscious that if an animal is tolerated to eat feces, then the dog may develop the taste for this particular matter and may continue the acquired habit. So once the behavior is changed, no opportunity for explication will be given. If the animal is eating litter, gravel, or the feces of other species, strolling in an area that is thoroughly cleaned up will help stop this practice.
