Q. How often does the dog need to go to the Vet?

Your dog should have an annual check-up and you should discuss what vaccination option are available (These can vary depending upon the latest research) Otherwise only if your dog is hurt badly (obviously). If pup isn’t eating but is bright and happy and behaving normally, then you can wait for 2 or 3 days before you worry. But if pup is drowsy or stumbling then get to vet quick. Any frothing at the mouth and pup is lethargic is also urgent. Changes in the poo will be an early indication if there is a problem coming.
