PP,I am glad you are getting so much good advice from Growler,she is a wonderful girl.
My Rocky too has lost more weight and I am really worried,he is skin and bones
He eats very good,drinks a lot of water and pees a river,for a while he would vomit after drinking,only in the morning,but now that has stopped.
I am not supposed to bring Rocky to the vet before mid september,when he finishes the Prednisone,but I am not going to wait..
Good luck with Sampson
