What little studies they have done with small dogs show their bones and such remain unaffected to spay and neuter by 6 or 7 months and that there is no difference in doing it then or waiting. |
As I stated, Yorkies’ growth plates often close by eight months, and this can be determined by an X-ray. It’s not a question of whether growth plates will close; it’s whether the delay of the growth plates due to the removal of sex hormones affects their orthopedic growth.
“Bitches spayed at 7 weeks had significantly delayed closure of growth plates as compared to those spayed at 7 months, and those spayed at 7 months had significantly delayed closure of growth plates as compared to those left intact”
