So sorry to hear about Stella. Blasto is pretty nasty, but not unbeatable. It's pretty common for dogs to lose their appetites when they're sick, so it's important to keep her nourished. Some posters on this site even resorted to force-feeding when their dogs wouldn't eat. My Harley didn't completely lose his appetite, but I had a shepherd mix that wouldn't eat in her last few weeks (she was 14 & passed of old age) & it helped to try small portions of various foods to see what she liked & stick with that. The more disgusting it was to me, the better she ate, like boiled beef liver (totally GROSS!) & we went thru a lot of jars of meat varieties of baby food. I read on this board where some used a turkey baster to force feed their dogs & this kind of stuff is easy to pure & do that.
There's a newsletter on this board that has a lot of really useful information on it. I joined this board when Harley was diagnosed & seems like over the years, vets have learned more about Blasto & more are pulling thru. Took almost a year but we beat Blasto! Harley's pushing 15-16 now & starting to lose his battle with Father Time, so I hope Stella beats Blasto too so you can have a lot more years with her too.
