don't know if this is where this goes, but I just needed to thank everyone. My first bp is now in top shape. I bought him from Petco about 3 months ago (my first mistake- or maybe rescue?) and he had been sickly ever since.
the advice and suggestions I received here blew away the vets I had been to about him and I am very grateful. Weight is up, sheds are healthy, scale rot is gone, and he seems very happy.
Thank you all again!
