what makes dog urine change odor
âStrong Smelling Urineâ is also very common amongst male dogs that havenât been neutered. Hormonal changes take place which then trigger urine marking with a strong and rather nasty strong smelling urine odor. If you find your dog is trigger urinating, itâs your dogâs way of signalling to other male dogs and bitches where he is or it could be that heâs highly aroused.
