How to give puppy shots 
Talk with your veterinarian. 
Not all dogs are good candidates for home vaccination. Call or meet with your vet to determine if your dog meets the basic health criteria.
If you are concerned about how to give the shots, your vet can also talk you through the process or even let you watch a demonstration in-office. Vets technically lose money by having you home vaccinate.
