Uh oh, yes I can see that he's gotten thinner. Has he completely stopped eating, or is he eating a little? If he's not eating at all, I think that I'd call the ortho vet ASAP.
Poor, poor Yukon, I sure hope that the pano is gone really soon. In the meantime, there are some things that might help tempt him to eat. I know that you've tried using canned food as a gravy, but he had some trouble with diarrhea. Have you tried:
-a small amount of a different kind of canned food mixed with warm water? To tempt poor appetites here I use the canned Natural Balance Duck & Potato (easy on the stomach) and our 3 dogs really love it. I usually use 1/4-1/2 can mixed with water mixed with about 2 cups of dry and mine go wild for it.
-a little cottage cheese mixed with the dry?
-parmesean cheese sprinkled over the dry? I heard this one from Pyr Rescue
-a little grated cheese?
-maybe some fish oils? I don't know anything about them personally, but I know that some people have said that their dogs love the taste and they are very nutritious.
-different meats mixed with the dry (sorry, no specific ideas here since we humans here are vegetarian..ou
r poor doggies!
)
I know that the dairy products are sometimes pretty iffy for dogs with sensitive stomachs, so the cheesy ideas may not work, but I know that even Daisy can handle the duck & potato canned and she has IBD. Also, we've used it here to help the Sam gain weight and it worked pretty fast for him. I'm sure that other people will have more ideas for you, too.
BTW, I'll get to get to my e-mail tomorrow. We've been inundated here with birthdays the last week, so I'm a little behind. Sorry!
