We had friends that had a big Doberman who ate a tube sock. When she tried to eliminate it, they had to help by pulling it out.
Had a similar situation with a dog.
All of my stories are about one dog; our last Alaskan Malamute, the only one not bought from a proper breeder. A lady my mom met had a female, and she had bred her to a male who was supposedly a champion...we only met the sire after we had our puppy...such a mistake. My mom was, and therefore I am, a bit of a snob about malamutes, and while I don't need to show one, if I ever have one I want it to at least look like the standard.
So anyway, he also had mental problems that started slowly and ended up killing him...
He either swallowed or otherwise destroyed my most AWESOME bikini. I still think that I would have kept myself small enough to fit into it, if it hadn't been eaten. He snagged one of the side strings from under my door; my door was completely closed so he couldn't get in, but that dog worked his heiny off to get one of the strings to pull it into the living room.
He ate an ace bandage, and just like the tube sock above, there was some assistance in getting it out. The family had actually taken him up to the vet's office, and he was waiting for his appointment when he had to "go". Stepdad and I took him outside, where the ace bandage showed itself...stepdad put his foot on the end of it, and the dog (I can't type his name here b/c it's the name of a banned car service! think...the other name for Mercury) walked away, and no need for a vet visit.
Later, as he lost his mind, he would attack anything ORANGE. He started eating carrots whenever he saw my mom grating/peeling one. Oranges, too.
And the last thing he ate was a beach-sized, orange-colored, towel. My mom had left it out (or maybe I did, who knows) and it had been outside for ages. My mom noticed it, and decided to move it, and the dog (who was rather overweight by then because the person who took him running was away at college) noticed the whole thing, ran over, and grabbed the towel. Scared the pants offa my mom, and my mom was NOT a person to be scared by malamutes! She established alpha status over her very first malamute, when she was around 22, by actually BITING his ear when he acted up while on a long walk. That dog toed the line from then on, and even gave higher status to baby-me, when I took his prized tennis ball from him as a little baby. But this last dog...never understood that.
So he, as they say in Ratatouille, "horked it down", and it went too far down to be pulled out, was too big to pass...the vet gave my mom just the one, heartbreaking, option.
So for those of you with dogs who eat bad things...try to train them to NOT eat things, and to give those things up when the alpha person tells them to!
