Pica
Health and safetyRepeatedly eating things that are not food, such as socks, rocks, plastic, fabric or dirt.
How it works
Chewing is normal, and puppies in particular explore with their mouths and swallow odd things along the way. Pica describes eating the objects, and doing so repeatedly. The causes fall into a few groups. Medical ones include digestive problems, which veterinary references list as a trigger, along with other illnesses that change appetite. Behavioral ones include boredom, too little to do, attention from people when the dog grabs something, and compulsive behavior. Because the medical causes need treatment of their own, veterinary references advise ruling them out first. The main risk is physical: a swallowed object can block the stomach or intestines, which can need surgery, so a dog who eats non-food items needs those items kept out of reach while the cause is worked out.
What it looks like
A one-year-old dog has twice needed a vet visit after eating socks. The household moves laundry behind closed doors, gives her a daily stuffed food toy and a shred box of cardboard she is allowed to tear up but not swallow, and teaches a trade game so that dropping a found object earns a treat. Her vet also runs bloodwork to check for a medical cause.
Commonly confused with
- Coprophagia
- Coprophagia is eating feces specifically. Pica is eating non-food objects. A dog can show both, and both call for a veterinary check before they are treated as behavior alone.

Basket muzzle (Baskerville-style)
A conditioned basket muzzle lets a dog pant, drink, and take treats, so it's a safety tool, not a punishment. We use it for reactive dogs in public and any dog still learning to be handled at the vet.
