The issue is there are no real studies in small dogs that show there are orthopedic issues with a pup being spayed at 7 months before their first heat. In fact the one that was done said there were no issues therefor spaying before the first heat is still the best option. The mammaries do no develop before the first heat so there is no mammary cancer, no accidents that can happen when spayed before the first heat and no infection in the uterus. All signs still point to it being best to spay before the first heat.
