Some of these are instinctive, while others might have started in puppyhood and become habits over time. We need to familiarize ourselves with these behaviors to better understand our furry friends and ensure they don’t cause them any harm.

Here, we will help pet owners understand why their four-legged friends lick other dogs’ pee. Additionally, we will determine if this behavior can cause any harm to the dog’s health.

Without delay, let’s dive in!

Why Do Dogs Like Licking Pee?

Before we answer the question, "Why does my dog lick other dogs' pee?" you need to learn about the vomeronasal organ or Jacobson's organ. Located in the vomer bone, in-between the dog's nose and mouth, Jacobson's organ is responsible for this weird dog behavior.

The organ works to analyze large molecules like bacteria, pheromones, and other compounds and transmit the information to the dog’s brain. This comes in handy in mating, social interactions, environmental perception, and even hunting.

If you observe your dog while he’s licking other dogs’ pee, you will notice he somehow tilts his snout up and press the tongue against the top part of his mouth. Other breeds will curl up their tongue and freeze in place.

What the dog is trying to do is to get the urine near the vomer bone. As a result, the urine molecules can be more accessible to the vomeronasal organ, and the canine can decipher information related to the other dog.

What Information Is Hidden in Dogs Urine?

A dog’s pee comprises several components, including:

  • Bacteria
  • Sugar
  • Pheromones
  • Uric acid

By licking the urine, your dog can identify which food the other animal consumes, the estrous cycle, and infections or illnesses. The pheromones can help the dog determine the dog’s gender and heat availability.

Also, your dog might lick other canines’ urine because it contains traces of sugar, especially if the animal that peed before has diabetes or glycosuria.

Smelling and licking urine come naturally in dogs. As disgusting as it might be, there's no need to scold your pooch—the habit results from their canine instincts.

Does Licking Other Dogs Pee Hurt My Dog?

Canines have ancestral guts with more microbial activity than humans. That’s why they can eat feces, bones, decaying food, and lick pee without getting sick. So, you don’t have to worry when your dog smells or licks another dog’s urine.

Keep in mind that licking pee is one of the survival instincts in canines. Furthermore, your dog’s immune system can shield him from bacteria and pathogens even better than some pharmaceutical drugs.

That said, there’s a slim chance your pooch can get leptospirosis, a bacterial infection caused by spirochetes, which your friend can get by licking other dogs’ urine or stagnant water.

The signs of the disease vary from one dog to another. Some dogs might display mild symptoms and recover quickly from the illness, while in others, the disease can advance to a chronic stage and kill the animal. What's even worse, the disease can infect humans, leading to flu-like symptoms and sometimes kidney or liver damage. The sign and symptoms of the disease in dogs include:

  • Changes in frequency of urination
  • Diarrhea
  • Jaundice
  • Loss of appetite
  • Dehydrations
  • Extreme tiredness
  • Bleeding disorders
  • Leg swelling
  • Depression.

Thankfully, Leptospirosis is preventable and also treatable via antibiotics and supportive care. If you suspect your dog has the disease, consult your vet so he can get a proper diagnosis and treatment.

Are Some Dogs More Likely to Lick Other Dogs Pee?

If you have had more than a few dogs in your life, chances are you've noticed neutered male pups like to react more to licking urine. The reason for this is simply reproduction. Unneutered males are in the quest to find mating partners. By smelling and licking urine, they can identify females in heat.

Neutered males and spayed females don’t exhibit this habit. And if they do lick urine from other dogs, it’s because they’re trying to get some digestive enzymes or glucose.

Should I Allow My Dog to Lick Other Dogs Pee?

First and foremost, it’s important to remember that licking pee in dogs is normal. It’s their natural canine instinct and not a subject of worry. The best thing is to let the dog lick the urine in peace. There’s no need to yell at him because you will only make your dog feel bad.

But as we have said, there's a slim chance that your dog might get sick if he licks pee from a dog infected with Leptospirosis. To prevent such issues, follow the tips below:

  • Always vaccinate and deworm your dog so he can stay as healthy as possible
  • Provide him with fresh water regularly
  • Visit the vet if you observe any sign of the disease
  • You can brush his teeth or let him rinse his mouth with dog-friendly mouthwash if he has licked another canine's pee and clean your hands afterward.

Besides that, always prevent your dog from drinking stagnant water. The spirochetes bacteria live mostly in stagnant water. When ingested by a dog, they can cause Leptospirosis. Also, never let your dog lick you after licking another dog's pee.

Final Thoughts

A dog uses his nose and tongue as translation devices. These two senses of organs make it easier for the dog to understand the world via the vomeronasal organ. That’s why it’s normal for dogs to sniff and lick each other.

If your pooch licks another dog’s pee, don’t get weirded out because this is an instinctive behavior in all canines, domesticated and wild. It’s their way of finding mating partners and getting information about other canines. We can compare pee liking to gossiping in humans, minus the verbal cues.

Lastly, your dog will remain healthy after licking another dog’s pee, especially if he’s dewormed and vaccinated. However, if your four-legged friend’s immune system is weak, there’s a reason to get concerned. You might need the help of a behaviorist to help your dog stop licking other dogs’ urine.
