Pogo is 16, blind and grumpy. It is time for his 3 year rabies shot. The vet said, we should discuss, meaning it will be up to us to decide. Have you guys always continued with rabies vaccines regardless of age? I believe our vet is concerned that if Pogo ever bites someone he will need to be put down. He is never out with the general public, so I am trying to evaluate the risk. Thoughts?
