Thanks Sandra,
No agreement with the breeder.
I just thought it was 'the right thing to do' but since i don't really have a valid response to my partner i am quetioning for what is right for the dog. Our family dogs have always been big backyard dogs (and female at that) so i hadn't really considered not desexing him.
I guess seeing so many rescue dogs etc i thought it was the right thing to ensure there would be no 'accidents' we could be repsonsible for. Perhaps it should be left for now and if our circumstances change and we are in a different living arrangement then consider it when he is older or if he starts getting a little hormonal!
