yes I think they can, but I am sure you can also find one that will be ok with it, specially considering the dogs age... I personally have decided to not vaccinate my pups as often as it is suggested by a vet (my dog has had reactions to the vaccines) and will be using Nosodes instead, I have also switched to a holistic vet which makes things easier as I know she wont refuse to see him if he is not "up to date" with shots.
