The Question
“Hi Dr. Paola!
I have a 2-year-old Chawinnee called Little Boy. Recently, he started licking other dogs’ pee, and then he pees on the spots himself and licks that up too. What could be the cause? “– Crystal
Quick Info about Little Boy
Hi Crystal,
This behavior, although unpleasant to witness, is actually quite common among dogs. When your two-year-old Chawinnee licks other dogs’ urine, or his own after marking, he is using his vomeronasal or Jacobson’s organ, a special sensory structure located on the roof of his mouth. This organ allows dogs to detect pheromones and chemical signals that convey information about another dog’s sex, hormonal status, and even emotional state. In simple terms, he is “reading messages” left by other dogs, much like scrolling through social media updates.
In a young, otherwise healthy dog, this behavior is usually normal and related to curiosity, social communication, or even mating instincts if he is intact. Occasionally, dogs may develop an increased interest in urine if they are experiencing greater thirst or changes in urination patterns, which can be associated with metabolic diseases such as diabetes mellitus or early kidney issues. These conditions are uncommon at his age but not impossible, as congenital or genetic factors can occasionally cause early onset.
If Little Boy seems well otherwise, with normal energy, appetite, and drinking habits, the behavior is likely harmless. Still, if you ever notice that he drinks or urinates more than usual, or if his general demeanor changes, it would be sensible to schedule a veterinary checkup with a urinalysis and basic bloodwork. Providing him with more enrichment and mental stimulation can also help redirect his curiosity toward more appropriate activities.
Best,
