Why Does My Male Dog Lick Other Male Dogs Pee?

  • Male dogs engage in urine marking behavior to communicate with other dogs, leaving their scent as a form of territorial marking and social signaling.
  • Licking other male dogs’ pee is a common behavior observed in intact (non-neutered) male dogs.
  • This behavior is driven by the presence of pheromones in the urine, which contain chemical signals that convey information about the dog’s sex, reproductive status, and overall health.
  • By licking another male dog’s urine, a male dog can gather valuable information about the scent-marking dog’s identity, dominance status, and potential mating opportunities.
  • The act of licking another male dog’s pee may also serve as a way for intact males to assert their own dominance or challenge the dominance of other males in their territory.
  • While this behavior is more commonly observed in intact males, neutered males may also engage in it due to residual hormonal influences or learned behaviors from their intact counterparts.
  • It is important to note that this behavior should not be confused with homosexual tendencies in dogs. Dogs do not possess sexual orientation as humans do; rather, they are motivated by instinctual drives and social dynamics when engaging in such behaviors.

This form of communication is particularly significant in the canine world because dogs rely heavily on their sense of smell to understand their environment. By licking urine, dogs can detect pheromones and other chemical signals that are not easily perceptible to humans. Through this intimate act of sniffing and tasting urine, dogs are able to establish a complex network of social connections within their community.

Scent Marking through Urine Licking

Licking urine also plays a role in scent marking, which is the process by which dogs leave olfactory messages for others in their territory or social group. When a dog licks another dog’s urine, it not only gathers information but also leaves its own scent behind. This reciprocal exchange helps create a cohesive social structure among dogs by reinforcing existing hierarchies and territorial boundaries.

Benefits of Canine Communication through Urine Licking

  • Establishes social bonds between individuals
  • Aids in recognizing familiar members within the social group
  • Provides information about health status and reproductive state
  • Facilitates mate selection and identification of potential rivals
  • Contributes to scent marking for territorial establishment

Examples of Canine Communication through Urine Licking

  • A submissive dog may lick the urine of a dominant individual to convey deference and respect.
  • Dogs in the same social group may engage in mutual urine licking as a form of greeting and reinforcing their bond.
  • Males may lick the urine of females to gather information about their reproductive status and suitability for mating.

Why Male Dogs are More Inclined to Engage in This Behavior Compared to Females

Male dogs are more inclined to engage in the behavior of licking urine compared to females due to their instinctual and biological factors. One possible reason is that male dogs have a higher level of testosterone, which plays a significant role in their sexual and territorial behaviors. Testosterone influences their scent-marking behavior and can make them more interested in investigating and licking the urine of other dogs.

Additionally, male dogs may be motivated by pheromones present in the urine of female dogs. Female dogs release different chemical signals through their urine during different stages of their reproductive cycle, and these pheromones can attract male dogs. By licking the urine, male dogs can gather information about the female’s reproductive status, which helps them determine if she is ready for mating.

It’s important to note that not all male dogs exhibit this behavior, as individual preferences and experiences can also influence their inclination towards urine licking. Factors such as socialization, environment, and training play a role in shaping a dog’s behavior as well.

Role of Testosterone

Testosterone is a sex hormone that is primarily produced in the testes of male dogs. It plays a crucial role in various aspects of their physiology and behavior. In terms of scent-marking behavior, testosterone levels impact the intensity and frequency with which male dogs engage in marking behaviors like urinating on objects or territory. The higher the testosterone levels, the more likely they are to engage in these behaviors.

Socialization Effects

The socialization process during a dog’s early development also influences their inclination towards urine licking. Dogs that have been exposed to different smells, including other dog’s urine, during their critical socialization period (between 3-14 weeks old) may develop a curiosity or interest in investigating scents, including urine. On the other hand, dogs with limited exposure or negative experiences during this period may be less inclined to engage in such behaviors.

Individual Variation

It’s important to recognize that not all male dogs exhibit the behavior of licking urine. Just like humans, dogs have individual preferences and experiences that shape their behavior. Some male dogs may show more interest in urine due to genetic factors or particular environmental influences, while others may not find it as appealing. Therefore, it’s essential to consider each dog’s unique characteristics when exploring this behavior.

  1. Testosterone levels influence scent-marking behavior.
  2. Socialization during early development can impact curiosity towards scents.
  3. Individual variation plays a role in a dog’s inclination towards urine licking.

Potential Physiological and Hormonal Factors Behind Male Dogs’ Interest in Licking Urine

1. Pheromones

One potential physiological factor that may contribute to male dogs’ interest in licking urine is the presence of pheromones. Pheromones are chemical substances secreted by animals, including dogs, that can elicit specific behavioral responses in other individuals of the same species. Male dogs have an exceptionally keen sense of smell, and they can detect various pheromones present in urine, such as those related to reproductive status or social signaling. By licking urine, male dogs may be gathering important olfactory information about other dogs in their environment.

2. Testosterone Levels

Another hormonal factor that could influence male dogs’ behavior of licking urine is testosterone. Testosterone is a hormone primarily associated with male characteristics and behaviors, including territorial marking. Research suggests that higher levels of testosterone can increase a dog’s motivation to engage in scent-marking behaviors, such as urinating on objects or licking the urine of other male dogs. This behavior may serve as a way for males to establish dominance or communicate their presence to potential rivals.

3. Social Interaction and Communication

Male dogs’ interest in licking urine could also be attributed to social interaction and communication within their canine community. Dogs rely heavily on scent cues for communication, and by engaging with the odor left behind by other males, they may gather important information about the individual’s identity, health status, or reproductive condition. Licking urine might serve as a form of non-verbal communication among male dogs, allowing them to convey messages or establish social bonds.


In summary, potential physiological and hormonal factors behind male dogs’ interest in licking urine include the presence of pheromones, testosterone levels, and social interaction. The complex interplay between these factors contributes to the behavior and communication patterns observed in male dogs. It is important to note that individual variations and environmental factors may also influence the extent to which male dogs engage in this behavior. Further research is needed to fully understand the underlying mechanisms driving this intriguing aspect of canine behavior.
