I'm a fairly new piggie owner. I've noticed for the past day or so that my sweet girl Paisley is breathing harder than normal. She is eating and drinking normal. i don't know if I should be concerned yet and take her to the vet yet. Could it be a possible upper respiratory infection? If i do have to take her to the vet, how much would it approximately cost? I just don't want it to cost an arm and a leg to take her to the vet. Thanks for your help you guys!
