Sorry guys , but I think Dexter takes the cake. 3 months ago, I took Dex to the vet for some infected hair follicles. After the visit, I put him back in my car before paying. He is quite dog-aggressive, and there was a dog that looked like it was about to go to the Bridge waiting in the reception area.
Anyhow, my gf and I get into my car, and go to the Farmers Market to grab some grub. We could not find his leash (4 ft. nylon.) I called the vet, he said he hadnt seen it. I figured it fell out of the car, an did not think much of it.
8 days later, I see Dex walk into his kennel and throw up. I go to investigate, low and behold I see around half of his leash with the metal buckle end.
As I am speed dialing my vet, he gives me the look like he needs to go potty. I take him outside, and proceed to pull 3 feet of nylon leash from his butt. At first I though it was a hanging poop (a la tennis ball fuzz) but I began to pull and it seemed like it never ended.
I felt horrible that he had it inside him for 8 days, but he never showed any signs of anything being wrong. If only I had a camera, as I was pulling, it looked like I was walking him from the wrong end, if you know what I mean.
I took him to the vet just to be safe, and he got a clean bill of health.
I know around 4-5 other pittie owners whose dogs have swallowed leashes before, the owners didnt even know till they pooped it out.
Your pooch should be fine, just pay close attention and take him to the vet if you see anything suspicious.
