I've had her at the vet in the last month looking at the one pad with the growth. THe option was surgery to try and remove any infection but he wasn't even sure that would work so we've continued with the regiment I was on. He did blood work then and I don't know about the thyroid but she didn't have bone cancer. She's eating well. Been on heartwork meds since we've had her and she stays inside the house unless she has to potty and then right back in. She's a mixed breed and has had problems with her feet, cysts, etc for the last three or four years. Things seem to be deteriorating and I know i'm going to end up losing her to these feet but she eats and is happy and I just don't know what to do.
