thank you for the answers so far.
and she is eating Diamond Puppy food right now. It's the same thing that i am giving to my 6 week old boxer and apparently he can not have ANYTHING with corn, soy, and all those other things in it. This dog food was recommended to me by his breeder and i was told that it would also be an excelltent food to give to my mom's yorkie. She seems to like it. But i'm pretty sure that it is not the food that she is allergic to because she began making that noise within the first couple ours that we had her (before we even bought the puppy food to feed her). Now that i'm really thinking about it, it does seem like she usually gets her coughing episodes whenever she is excited, or trying to calm down after being excited or after playing with my puppy. She is very hyper. Oh and right now I am just using some puppy shampoo on her with a lavender scent. Should i switch to something that is not scented? Or maybe oatmeal based? Any my mother did give her some benadryl the other day...but i dont think it did very much to help her except make her a little drowsy. i would rather not start her on medicines untill i try everything else that i can to help her.
