Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 12 years and 1 month old
My dog has been walking for 16 hrs straight in my back garden. I had to chase him in as he wouldn’t come and then had to hold him down to stop him carrying on. He also seems to be having trouble opening his mouth, he has lost a lot of weight in just under a week. He is a boxer cross mastiff and about 12 yrs old
