My Yorkies and Chihuahua always get a one year shot. Sam, at 55 lbs. gets the 3 year shot. I just feel more comfortable about it. Our Yorkie puppies always have a bad reaction to their second set of shots unless I remember to remind the vet about it before (I thinks it's the lepo ???). So I don't like to give the Yorkies any larger dose of medication than is absolutely necessary. |
