We found out today Bridget's tumor was benign. It was a "follicular something" tumor and once dogs and cats develop the first one, they are a lot more likely to develop them in the future. Luckily they're also most likely to be benign in the future too, but hopefully she doesn't get any more. If she does, all we can do is have them removed. There's nothing we can do to prevent them and there's no way they'll go away on their own once they surface. As for this one, they did get all of it and the stitches have to stay in for 10-14 days. We have to keep the cone on her during the day but at night when we can watch her we let her run around without it.
Her collar threads through it and it's too much trouble to keep taking it out and putting it back in, so we let her run around naked when she's not wearing the cone.
She's acting normally and when we take the cone off she runs around like crazy enjoying her freedom. And she enjoys the pieces of chicken she gets with her pills. Bridget likes chicken very much.
