My vet will only do One shot a week! They really spread them out on a Yorkie. Also the rabbies shot is the same dose for all dogs... i was concerned about that and my vet reduced the dose for him! I was told a horse gets double the shot of a dog!!!! Yorkies and Saint Bernards get the same dose unless you ask for them to reduse the dose!!!! I can't believe it but thats what I was told!
Hope this helps....
