WOW! What a discussion...
Some talk like the nuetering is going to happen to them!
Then there is the ...I don't want me dog "squating to pee like a girl" group.
I am not a vet... but speying a female will reduce the chance for cancers in the female parts that are removed for sure...the same goes for males and there parts.
Every Vet I have known says it will reduce the risk of cancers in females.
I have always nuetered my dogs. My springers could hunt with the best of them. None were fat becuase I watched there diet. As a big time duck hunter, I have seen many, many, many fat male and female labs that were not nuetered.
I now have a gordon setter. He was showing so much promise when he was a pup, I had visions of the breeder (Norm Sorby) wanting to use him as an ocasional stud. I refused to neuter him until he kept sraying everywhere, including in the house! My wife "convinced" me I had to do it. He is now a LEAN, FANTASIC, Hunting MACHINE. When I need another dog, I'll call Norm.
I would love to hear from a vet and see some scientic studies.
