Momo loves playing w/his ball & my long hair gets on it. He swallows it sometimes (if I don't catch it 1st & wash it) & he will make these strange noises like there's something stuck in his throat. It goes away in the morning, but he'll poop out my hair! I have to pull it out along w/his poopie! I'm an obsessive floor cleaner now, I see my hair, I pick it up right away.
One time, he was making those noises again & I opened his mouth, my hair was half way down his throat! I pulled it out, like 2" came out.
It really helps if you get it on video & show your vet. My vet knew right away that it was reverse sneezing & told me not to worry.
