well my mom wont take her to the vet. she says it is because of the chews i feed her daily. i stopped feeding her the chews yesterday. she hasnt choked since. and today we went to walmart and got her a new harness. my mom is putting it on her now to see if it fits. thanks so much everyone, your all so kind. i can always count on pt! we will give a vet a call this weekend and see what they say.
