My vet hasn't asked me one way or the other. Maybe she talsk to her Joe Blow clients about spaying and neutering, but she knows I'm a breeder (and she knows she's gotten money from me in the past from puppy exams, c-section, x-rays, heath certifications, etc etc, and knows that will stop if my dogs are altered). I think though, that she'd be a bit of a hypocrite if she really pushed spaying/neutering. She bred her little mixed breed dog a few times, and she bred her IWS to a standard poodle twice now. Any of my vets I don't go to regularily have never even asked me if my dogs are unaltered (other than the oens I go to for repro stuff obviously). Around here (BC) I don't think it gets pushed one way or the other.
