My dog has a recessed vulva. Doctor recommended that I have her spayed after her first heat to prevent UTI because many dogs will outgrow the recessed vulva after the first heat. I have several questions for those who had their dogs spayed after their first/second heat. 1. Did your dog mark like a male dog during her heat? 2. After she was spayed post her first or second heat, did she retain the habit of marking? I’ve heard that a male dog neutered after six months will often retain the instinct to mark, even after the neutering. Not sure about females. Thanks.
