can the vet tell if a dog has been vaccinated. also what shots does he need and is there a place where its not too expensive to give shots and get him spayed.
Your vet should be able to run titers to determine if certain vaccines were given. These tests are not cheap and can not tell you when the vaccines were given. I am sure there is a low cost vaccination clinic close to you. Call your local animal shelter or pet store for help. vetcrae
