Oh no….I am so so sorry. This must be heartbreaking for you.
I honestly don’t think there is anything you can give him to get rid of this fluid. This, as I’m sure you know, happens with cancer.
The only way to get rid of it is to have it drained by the Vet. It won’t go any other way.But I think it will just build up again within a short time.
Again my heart goes out to you.
Thank you so much for addressing my situation. You wrote: “The only way to know if it is malignant is to do a biopsy. If you are going to do that do the splenectomy” Does that mean the splenectomy will be the biopsy? There is a Cancer Center for Dogs in Carlsbad, CA, If it were you would you go with an organization like this rather than an individual vet? http://www.cvsangelcare.com/About-ACCC/
So appreciative,
