Do dogs find each other attractive?

Dogs are highly social animals that form close bonds with other dogs. But do dogs actually feel attraction or desire for certain other dogs, in the way that humans feel attraction? This is an interesting question that dog owners often ponder. While we can’t get inside a dog’s mind to understand their subjective experiences, scientists have done research to better understand dog social behavior, attraction cues, and mating preferences.

Do dogs have preferences for certain mates?

Research suggests that dogs do prefer certain traits when choosing a mate. Some key findings:

  • Male dogs tend to prefer females that are in heat. They can smell pheromones from a great distance.
  • Both males and females often prefer mates that are not closely related to them.
  • Females may favor males that have resources or high social status.
  • Males compete with each other for access to females in heat through dominance displays.
  • Male and female dogs both initiate courtship behaviors with preferred mates.

So while we can’t definitively say dogs experience romantic attraction, their mating behavior does indicate they make selective choices rather than mating indiscriminately.

Signs of attraction and desire in male dogs

When a female dog is in heat, males respond very enthusiastically. Here are some signs a male dog is attracted to a female:

  • Increased sniffing and attention focused on her rear end
  • Constant following her around and attempting to mount
  • Licking the female’s vulva
  • Erect penis and ejaculation
  • Standing guard and protecting the female from other males

The male dog’s entire focus narrows in on the female in heat, whom he will try to mate with repeatedly during her fertile period. This indicates the female in heat is highly desired and attractive to the male.

Signs of attraction and desire in female dogs

Female dogs give off more subtle signals of attraction than males. Signs a female is interested in a male dog include:

  • Play bows towards the male
  • Tail held up and wagging in the male’s presence
  • Initiating play with the male
  • Licking the male’s face
  • Letting the male sniff her vulva
  • Standing still while the male mounts

These behaviors indicate the female is receptive to mating. She will continue allowing the male to mate until she is no longer in heat. So while females are not always enthusiastic, they do make a choice whether to accept a male or reject his advances.

Dog mating strategies

Dogs have evolved a mix of mating strategies, ranging from monogamous pair bonding to competitive mating:

  • Some breeds like beagles tend towards monogamy, with males guarding females from other suitors.
  • Other dogs are polygamous, with dominant males mating with multiple females.
  • In multi-dog households, dogs often avoid inbreeding by not mating with their siblings.
  • Females may sometimes mate with multiple males when in heat to ensure pregnancy.

So dog mating behavior involves both selectivity and flexibility. The patterns observed match what we would expect from an animal influenced by both evolution and human intervention.

Do dogs fall in love?

While humans associate concepts like love and attraction with our mating instincts, it is debatable whether animals experience these same emotions. Dogs clearly have social preferences and patterns of desire for certain mates. But whether they feel an emotional bond akin to romantic love is unknown. More research is needed on the neurochemistry behind bonding and mating in dogs to better understand whether they have emotions analogous to human attraction, affection, and attachment.

Reasons dogs may be attracted to each other

There are several evolutionary drives that likely motivate mating behaviors and preferences in dogs:

  • Heat detection – Male dogs are very focused on determining when females are in heat based on pheromone signals.
  • Instinct – The innate drive to mate is very strong in mammals.
  • Reproduction – Passing on genes drives males to seek out fertile females.
  • Pleasure – Mating releases neurotransmitters that are experienced as pleasurable and rewarding for both males and females.

Dog social needs and bonding instincts may also contribute to selective mating patterns observed in some breeds.

Ways dogs display attraction

Dogs use their highly evolved senses to determine which individuals seem most attractive as potential mates. Types of cues dogs use include:

  • Smell – Scenting pheromones is a major attraction factor, especially for male dogs.
  • Sight – Visually observing sexually dimorphic traits.
  • Hearing – Listening to mating calls and signals.
  • Touch – Physical contact and inspection is important before mating.

Dogs integrate signals from all of these senses together when making mating choices. The mix of factors considered depends on if the dog is male vs. female and what breeding strategy they typically follow.


While we can’t know for sure what dogs subjectively feel or experience, research evidence suggests dogs do discriminate between potential mating partners instead of mating indiscriminately. Male dogs in particular show very strong attraction and focus on females in heat. Female mate selection tends to be more subtle and choosy. This selectivity indicates dogs have preferences and find certain characteristics desirable in a mate. However, more research is needed to determine if dogs can truly feel something akin to “love” or “attraction” the way humans experience it. Understanding dog mating strategies, signals, and motivations can provide helpful insights for owners on canine social behavior.
