I have seen 4 month olds that leg lift so I like to have it done before they go to new homes but a lot of vets won't let clients have it done on their dogs before 6 months. I wouldn't wait much past it because that is usually about the time testosterone becomes the driving force for the behavior. I think larger yorkies may have this a little later but each day you're taking a chance and once it starts, you can't stop it. JMO |
