My vet reminded me of shots only once, I told her I didn't believe in them and expalined why. I asked for titers and they didn't need any vacs. She hasn't mentioned the shots since. Not even the rabies, which is the one that causes the most danger to dogs. My 10 yr old hasn't had a rabies since she was 2 yrs and my 5 yr old got the last one at 16 mos. It is mandatory but left to our discretion.
