We adopted our boy about 3 months ago and he’s been pretty easygoing and sweet. However in the past month he started eating random things. So far he had chewed/swallowed small plastic parts, ketchup packets, whole banana peels, pebbles/acorns/who-knows-what in our yard. We have been more careful with leaving things on places he can reach now, but it’s almost impossible to pick up all the inedible things in the yard, let alone on any given day birds or raccoons or cats can drop new things off.
We’ve also started to put his muzzle on him when he goes to the yard, but today he managed to eat a small pebble even with muzzle on. He also has resource guarding and would growl and snap or bite if we try to take take things away from him. We feel extremely awful because he might get sick from eating inedible things, and in fact once he vomited after gobbling up a ketchup packet from our dining table (poor guy). We start to feel like we are two really crappy dog parents.
Is this pica? Does anyone have experience dealing with this or have any advice? We haven’t taken him to see a vet yet because this is pretty recent but at this point it looks like a visit is unavoidable. Thank you everyone in advance!
Some additional info: he is a 75lbs two and half year old. We feed him 4 cups of kibble with obedience training and treats throughout the day. He regularly freezes on the walk so although we try to walk him 30 minutes to an hour per day, he may or may not get that amount depending on whether he freezes. We live in a relatively big house with a medium sized yard.
