I'm really upset. Every once in a while Ferdinand will make this weezing noise - he'll do it 3 or 4 times then be fine. I did a bunch of research trying to figure it out when he first started doing it. I read that a sound like a "goose honk" is a clue that it's a collapsing trachea - but he'd never done that at all.The vet said it could be allergies and tried to get him to do it so she could hear it, but wasn't successful. Well, today he started doing it again and it sounded just like a goose honk.
It makes me want to

. I feel so bad for him... I just hope it doesn't get worse.
