I have a lab and a lab/dalmation mix 12-wk old puppy. Both are overdue for vaccinations. I've seen vets give these injections. I would like to give them myself and save money. Could you tell me what size needle to use and in what muscle or sub-q tissue these should be administered into?
At this age I recommend a visit to the vet because a good physical exam is very important. Most vaccines are given subcutaneously. The needle size is usually 22 g. vetcare
