Pica in dogs may not be a familiar term to many pet parents, but it describes a surprisingly common behavioral and medical condition where dogs consume non-food items. As a vet with 14 years of experience, I’ve seen everything from socks and stones to toys and plastic bags eaten.
Many curious canines have been known to indulge in this unusual habit. While it might initially seem quirky or mischievous, pica is far more than a passing phase. It can pose serious risks to a dog’s health and wellbeing if left unaddressed, making awareness and early intervention essential.
Below, I’ll explain exactly what pica in dogs is, the common symptoms and causes, and how we diagnose and treat it. I’ll also discuss why it can be dangerous, and when you should seek urgent veterinary attention. I will help you recognise the signs early so you can protect your dog’s health and wellbeing.
What is pica in dogs?
Pica in dogs is the repeated eating of non-food substances that have no nutritional value. These can include stones, soil, fabric, plastic, metal, sticks, paper, or even feces. While many dogs will occasionally chew or mouth unusual objects out of curiosity, pica is different – it’s a compulsive behavior or symptom of an underlying problem.
In veterinary medicine, pica is not considered a diagnosis in itself, but rather a sign that something else may be going on. This can be physical (such as a gastrointestinal disorder) or psychological (such as anxiety or boredom). In some cases, pica can be dangerous enough to cause life-threatening complications like intestinal blockages or poisoning.
Symptoms of pica in dogs
The most obvious symptom is your dog actually eating non-food items. However, there are other signs that might indicate pica or complications from it, such as:
- Repeatedly picking up and swallowing inedible objects
- Vomiting or retching
- Diarrhea or constipation
- Abdominal discomfort or bloating
- Loss of appetite
- Lethargy or weakness
- Signs of pain when touched around the stomach
- Evidence of objects missing from the home or garden
If your dog has swallowed something that could cause a blockage or be toxic (e.g., batteries, sharp objects or fabric), you should contact your vet immediately.
Causes of pica in dogs
There are several possible causes of pica in dogs, and sometimes it’s a combination of factors. The most common include:
- Nutritional deficiencies – Low levels of certain minerals or vitamins can trigger unusual eating habits.
- Medical conditions – Disorders like inflammatory bowel disease, liver disease, anaemia, or endocrine issues (such as diabetes or thyroid problems) may be linked.
- Behavioural issues – Stress, anxiety, separation anxiety, or boredom can lead to repetitive chewing and swallowing of inappropriate objects.
- Learned behaviour – If a puppy discovers that eating something odd gets a reaction (even if it’s negative), they may repeat it.
- Breed tendencies – Some breeds, such as Labradors and Spaniels, are notorious for eating things they shouldn’t.
- Age-related changes – Older dogs with cognitive decline may start to display unusual eating behaviours.
How do you treat pica in dogs?
Treatment for pica in dogs depends on the underlying cause. Your vet will usually start with a full health check, possibly including blood tests, fecal analysis, and imaging (such as X-rays or ultrasound) to look for both the cause and any complications.
Management options include:
- Medical treatment: Addressing any underlying illness, such as treating anemia, correcting nutritional deficiencies, or managing gastrointestinal disease.
- Dietary adjustments: Feeding a balanced, high-quality diet and ensuring your dog’s meals meet all nutritional needs.
- Behavioral modification: Using training and positive reinforcement to discourage object-eating and redirect your dog’s focus.
- Environmental management: Removing access to tempting items and providing safe chew toys or puzzle feeders.
- Increased stimulation: Regular exercise, interactive play, and mental enrichment to reduce boredom and anxiety.
- Specialist referral: In some cases, your vet may refer you to a veterinary behaviorist for ongoing support.
It’s important to remember that pica can’t always be “cured” instantly – in many cases, it requires consistent management and patience.
Is pica fatal in dogs?
Pica can be fatal depending on what is eaten and the quantity. The most common and dangerous risk is an intestinal obstruction. This is when the swallowed object blocks the digestive tract. This is a life-threatening emergency that often requires surgery. Perforation (where a sharp object pierces the stomach or intestines) and poisoning from toxic substances are also possible.
Even if your dog passes the object without obvious harm, repeated ingestion can cause chronic irritation, internal injury, or infections. That’s why it’s so important to address pica early, rather than hoping your dog will “grow out of it.”
Pica in dogs can be frustrating, worrying, and potentially dangerous, but with the right veterinary support and a tailored management plan, most dogs can live happy, healthy lives. If you ever suspect your dog has swallowed something they shouldn’t, don’t wait for symptoms to develop – call your vet straight away.
By recognizing the signs, understanding the possible causes, and taking steps to treat or manage the behavior, you’ll be giving your dog the best chance of avoiding complications and enjoying a safe, fulfilling life.
