There are at least 8 strains of lepto that dogs can get and I don't know of any shot that is good for mre than 2 of those strains. I would never give it to my yorkie unless there are special circomstances. Lots of vets recommend it cause that's what they are taught in vet school. The shot can be fatal in small breeds. If you insist on getting it it is best to wait in the vets office 20 minutes after the shot so they can give epi if there is a reaction |
