[/]"Female dogs that were spayed before 5 and one half months did however have a higher incidence of urinary incontinence."[/]
My own anecdotal experience is that this is true and if it happens, is a very serious impediment to ever successfully rehoming the dog. Young dogs with incontinence tend to have to be adopted by a person within the rescue network.
As I said before, AAS's insurance that none of our dogs will become breeders is careful selection of the new home.
The quality of homes, not the quantity of homes, is the only standard that addresses the moral obligation to each animal whose future happiness or unhappiness is determined at the moment it changes hands. Taking animals into one's "care" that can't be properly cared for is immoral, and that includes selling them to people who are not capable of seeing to the animal's life-long needs.
Taking in animals when one's facility itself causes disease and distress is also immoral. Causing or permitting distress is an prosecutable offence under the PCA Act. Killing the distressed as a solution to facility-caused distress is plainly self-protection, not animal protection.
