| Are you asking because your pup is having reactions from distemper, or do you want to know because you are comtemplating a vet visit ? To answer your question, and to tell you the truth I have never had any reactions or problems in any of my dogs from this vaccination. Your pup may appear tired after, may want to drink lots of water, but I think all that is normal as he has been introduced to a substance in his body that is particularly foreign, but absolutely necessary if you have ever seen a small animal die of distemper. |
