Why does my puppy's pee smell like fish?
Your dog may have a urinary tract or bladder infection, as one of the more common symptoms is a strong, foul smelling odor.
Also, another thing that comes to mind is the fluid that's secreted from the dog's anal glands - this fluid has a very distinct, strong, fishy smell.
Dogs also lick because they like the taste of an owner's salty skin and out of habit.
Mostly, with domestic Dogs, it's a sign of affection.
