our dog is a 12yr old lab/retr mix. in the last 2 years he has shown more weakness, his vomiting is every day ALL day now. he will eat for a few days and then stop eating for a week. his vomit is mucousy and snotty, foamy looking. he has had diarrhea he can barely make it up the steps and when he does he walks up sideways - stops - and then continues. he barely drinks any water. his hacking cough (as if he has a hairball or something) has been CONSTANTLY for the last 3-6 months
