Dogs on raw hork up food for a number of reasons.
Ate too fast, food too cold, ate too much, etc etc.
Betty will hork her food up (chicken w/skin on) repeatedly ... then EAT IT AGAIN.
LOL Gross! But she seems to enjoy it more the second time round.
Deme, I think maybe the raw diet isn't for YOU.. Jake seems to be doing fabulous on it. You, on the other hand can't seem to calm down long enough to take it as it comes. I get that, I have anxiety disorders.
Do you think maybe you should get him on a high quality canned food with some raw bones twice a week to help clean his teeth? Would that be something that is more comfortable for you?
