I don't know how it is in Texas, but, the vets around here, do like to wait with yorkies being so small until at least 5 mos. and also they want to make sure the testicles have dropped. If there is a lot of problems with humping, and the puppy is bigger, they will do it sooner, but, they still prefer to wait until the pup is at least close to 5 mos. |
