It could be that Thor is teething. He's the right age for it, and sore teeth would cause him to not have an appetite. I wouldn't be concerned about him having parvo if he isn't throwing up and he has solid poop. I would try to tempt him to eat by mixing his dry food with some wet food, or soaking his dry food with gently warmed low sodium beef or chicken broth. You can also try offering him some boiled white meat chicken (no bones) and white rice in small amounts several times a day. I would get him some puppy teething toys you can put in the freezer to harder and make really cold, and that will be soothing on his teeth.

    Hi there! Sorry to hear that Thor is not feeling well. The clinical signs you describe are concerning when they occur in a puppy as they can be seen with serious gastrointestinal infections such as Parvovirus. Other possibilities include intestinal worms and dietary indiscretion, among other possibilities. The sooner these conditions are treated the better the outcome tends to be. For this reason, I recommend that you have Thor evaluated by your veterinarian to check for these possibilities and to start therapy based on findings. At the very least they can address dehydration if present and start him medications to make him feel better. Good luck! Keeping my fingers crossed for your boy!
