Thank you everyone for your kind words, Im feeling better already! Especially not that I just got back from the Vet with Penny. The bump on her back that got bigger this month turned out to just be a yucky cyst and the vet drained it (this was quite disgusting). As for the hyperplasia in her mouth and the blister that popped yesteday from it, the vet put her on a expensive antiobiotic. My vet said there isnt really anythign that can be done about the type of hyperplasia that Penny has in her mouth

. So I dont know, I need to look into it and get other vet's opinions. Apparently its just something that boxers commonly get. Basicaly what it is, or what Penny's symptoms are is her gums get really swollen and get huge grape-sized blisters (I call them blisters, not really sure what else to call it) and they dont ever go away. Yesterday was the first time one popped and it bled which really freaked me out.
BUt anyways I also had a full blood panel done today so I can make sure penny doesnt have a thryoid porblem since she sheds sooooooo much and gained alot of weight. The good news is she is 2 lbs lighter than she was last time I took her to the vet. She now weighs 86 lbs
