Kittypuff, just because you can't see the problem doesn't mean there isn't one. If you don't know what lymphosarcoma is, it's a cancer. You can't see it, but it makes you feel like you have a really bad cold. But what it really does is kill you from the inside. This is what may be happening to your dog.

You know those cysts, bumps you found on her, well those are just signs of what she may have going on inside her.

Please take her to the vet. Don't let her get any sicker than she is.

Why don't you print these pages out and show your dad how bad it could be. Maybe he will change his mind.
