I saw this debate on another thread, and found it rather fascinating. I have a 5 month old intact male, and a 16 month old spayed female. Neither dog has a strong odour, unless they have rolled in fox poo.
However, I have noticed that my male does have a distinctively different smell than my female. It's not bad, nor overly strong. But it is distinctive....at least to me. Interestingly, he had a ridiculously STRONG puppy smell when we brought him home at 10 weeks. It was a sickly sweet puppy smell that permeated the whole house and lasted for a solid month before finally dissipating.
So I'm gonna throw this out there to all you folk who own males:
Do your boys smell like boys? Do they stink? Do they have no odour?
