Older dogs can get parvo, but it is much more serious in puppies.
I've seen a seminar also by one of the experts who says immunity can last 10 years or more. I've also talked to my vet about it who says that she has seen dogs get sick who have had titers and shown immunity. Everyone knows that vaccines last more than 1 year. No one knows exactly how long they last. Rabies has now gone to 3 years and I think the rest will too, but less often than that is risky.
I have gone to the 3 year rabies and 1 year on everything else. I think titers are a fabulous option for dogs who have had problems with vaccines or some of our smallest Yorkies. Otherwise, I trust my vet's experience on this. |
