Hi can someone tell me do u give a dog distemper vaccine in the muscle or under the skin?

No, you get the vet to do it.

Sorry but I just think it is a LOT safer to get your vet to administer any vaccines.

Here in Australia it is the ONLY way you can get your dog vaccinated and rightly so.

There are too many things that can go wrong from improper needle placement to incorrect dosage.
