Youre a great doggie mom girl,,, and I seriously doubt anyone here is goona say otherwise! Owning an naimal is costly ,, yes,, but your mom saying what she said was very ,,, well,,,,,, likewhat you said about it,,,, I wont say,, you know... Can you call your vet and ask a few questions? Perhaps they can advise you over the tel with a few suggestions? I know seeing a techinicion here rather then the vet themselves is ??MUCH cheaper and they are really good... no problems with diagnosies before,,, and if they arent sure,, only then do thay get the vet....the techs are like assistants,, nurses,, you know what I mean?

Maybe you can speak to your mom again later when you have calmed down and explain your concern and mention the chair piece... ask her why she is being the way she is?

Keep us informed.... from what you describe,, it does sound like a fatty pad......
