My pug has always been very good about not getting into most things, but for some reason he has a penchant for crayons and Playdoh. Fortunately they are non-toxic but I always find out after the fact when he produces rainbow-colored poop!
As a vet I've seen dogs (and cats!) eat a wide variety of items. Some of them have had to go to surgery and we've pulled out socks, underwear, dish towels, toys, coins, hair scrunchies, corn cobs, rocks, chunks of rawhide, slippers, pieces of garden hose, pieces of leather leash, you name it. Cats seem to go for ribbon/string and hair ties. One of our monthly veterinary publications has a contest every year for vets to send in their craziest x-rays of pets and what they have eaten, then they publish the top 10. Some of the x-rays have included:
- A Lab that had 14 golf balls in it's stomach
- A Boxer that had 3 lb of pea gravel in it's stomach
- A Jack Russel that had 1 lb of pennies and other coins in it's stomach
- A Pit Bull with an 11 inch steak knife in it's esophagus and stomach
- A cat with a TV antenna stuck down it's esophagus
- Another Boxer with an intact rubber ducky in it's stomach (you could see the outline and everything!)
