Poor Dodley and you! Finger's crossed that the latest tests show something
to work with.
When Buddy was sick sometime ago he got down to 11lbs and looked so frail
since he is a larger Yorkie. Old vet said it was the food, he had diahrea all the time. I tried so many foods over 4mos and home cooking, I finally changed doc's. New vet
wormed him. Turned out he had a male parasite in his intestines that was
causing him problems. 48hrs later he was back to normal. After 4mos it
was a parasite.
Hope you have luck finding out Dodley's problem and he also can get
back to his old self. Finger's crossed they find something.
