All four of my girls were spayed at close to one year, after their first heat, after growth plates were closed, and two of them had retained baby teeth removed then.
This was in accordance with my vet's advice, and was only slightly inconvenient having to go through one heat cycle and protect them from getting pregnant.
He also added that going through one heat cycle does not increase chance of mammary cancer, but every heat after does increase. Also, studies are showing a link to spay before 1st heat to urine incontinence in females later (more so in larger dogs than Yorkies,). |
