Our dog has not had any vacines for 3 years (he is 8 years now).
I stopped as he has quite bad luxating patella and it seemed to me there was no point to ongoiung vaccination (all puppy ones done and yearly for 5 years).
So far, so good...
The biggest issue we now have is that dog club and boarding kennels all want proof of vacination before we can attend. I have disputed this with our dog club from time to time....its a ongoing debate!
