Why do dogs hump legs

Most pet parents don't seem surprised when their male dog humps another dog, a pillow or a stranger's leg, but you may wonder why female dogs hump things? Especially female dogs who were spayed as puppies?

Harmless mounting here and there by males and females is normal with all dog breeds, but it's important to know when humping behavior might need to be addressed.

What Does Normal Behavior Look Like?

Whether you call it humping, mounting or thrusting, the behavior is natural in male and female dogs. For some dogs, it is a response to arousal. For others, it can just be a way to exert dominance and show that they're the top dog in the house.

Humping other pets, people or even the living room couch once or twice a day is not considered excessive. If even the occasional occurrence is bothersome to you or your family members, there are a few things you can do to limit or eliminate this quirky behavior.

Ways to Prevent Mounting

Pet parents often notice mounting behavior starting about the time a female dog enters her first heat. Many veterinarians recommend spaying or neutering your dog before he or she reaches that point to prevent unwanted behaviors. Neutering also prevents a surprise litter of puppies and reduces your pet's risk of testicular or mammary cancer. However, even dogs who are spayed or neutered might still exhibit some humping behavior from time to time.

The ASPCA recommends teaching the "leave it" command early for all dogs to leave unwanted objects alone. Once your dog knows this command, you can signal to her that she should step away from furniture, other dogs or guests. If you see your dog preparing to mount an object (by rubbing, licking or whining), you can say "leave it" and distract your four-legged friend with a toy or a more desirable activity. Although it may take some time to train your dog to do this, it may be the easiest way to stop unwanted humping.

When to Be Concerned About Dog Humping

Although dog humping is a normal behavior, there are times it can be sign of other underlying issues. Be careful to observe other behaviors that lead up to or accompany the humping to determine if you have reason to be concerned.

• Is the humping a sign of boredom? If your dog is lying around or pacing and then seems to start humping things, maybe she is just bored and need more playtime with you.
• Could your dog be trying to relieve an itch? Humping and excessive genital licking may be a sign that your dog has a problem, such as skin allergies or a urinary tract infection. If you notice your dog licking her backside, urinating frequently, having trouble urinating or showing signs of dehydration along with the humping, you may want to schedule a visit to the vet, says the ASPCA.
• Is your dog stressed? The ASPCA notes that male and female dogs may use humping as a way to relieve stress. Is there a new pet or new baby in the home, or did you recently change your work schedule? Sometimes little changes in a dog's routine can lead to her feeling stressed, and every dog responds to stress differently. Try to figure out what could be causing your dog to be uneasy, and do what you can to familiarize your pup with the new routine. If the stress-humping goes on for too long, it could become a very difficult habit to break and you may need to consider professional obedience training.

• Has the behavior just become a bad habit? When you have ruled out all other causes and just can't get over the "hump," it may be time to get your dog into obedience training. You may need to try a new approach like group socialization training, one-on-one training with a pro, or even implementing time-outs. If you and your vet have ruled out medical causes for the humping, take your vet's advice on the best way to move forward.

Why do female dogs hump things? For many reasons! Armed with a few answers, hopefully you and your canine friend can have less humping and more happiness.

Mounting, thrusting (humping) and masturbation are normal behaviors exhibited by most dogs. Dogs masturbate in various ways. They mount and thrust against other animals, people and objects, such as wadded-up blankets, dog beds and toys. Sometimes, dogs just rub against people or objects (without mounting them), or they lick themselves.

Puppies often mount and hump their littermates, other playmates, people and toys. Some experts believe that this behavior functions as practice for future sexual encounters. As puppies reach sexual maturity, they start to mount other dogs in sexual contexts. After they’re neutered or spayed, many male and female dogs continue to mount and even masturbate because they have learned that the behavior feels good.

Intact (not neutered) males will often masturbate if prevented from approaching a female in heat. Often, during courtship, females in heat mount and hump their male “suitors.” Female dogs also commonly mount and hump other females when one or both are in heat.

Why Does Your Dog Do It?

Sexual Behavior
Masturbation is part of normal sexual behavior for both altered (spayed or neutered) and intact dogs. Both male and female dogs mount other dogs, people and objects. Most people don’t realize that this behavior isn’t limited to intact male dogs, nor do they know that neutered males can display erections and ejaculate just like intact males. Sexually motivated mounting and masturbation are often accompanied by “flirtatious” body language and courtship behavior (tail up, ears rotated backward, licking, pawing, play bows, etc.).

Play Behavior
Sexual behaviors, including mounting and thrusting, are part of normal play behavior. Dogs don’t usually display erections or ejaculate in the context of play. Some poorly socialized or undersocialized dogs excessively mount other dogs in response to play solicitation. They don’t seem to know how to play well and get overaroused during play.

Response to Stress or Excitement
Some dogs respond to stressful or exciting situations by mounting or masturbating. For instance, after meeting a new dog or person, an aroused and excited dog may mount another dog, his owner or a nearby object, like a dog bed or a toy.

Compulsive Disorders
Masturbating can become a compulsive habit, especially if a dog does it in response to stress. Compulsions like mounting and masturbating can interfere with a dog’s normal functioning.

Social Behavior
Dogs sometimes mount other animals and people to display social status or control. A dog mounting for this reason may or may not display an erection, but he’s unlikely to ejaculate.

Medical Problems to Rule Out

Various medical problems, including urinary tract infections, urinary incontinence, priapism (persistent, often painful erections) and skin allergies, can influence a dog’s mounting behavior. These issues can be serious if not properly treated and require medical attention rather than behavioral treatment. Dogs suffering from one of these or other medical issues often spend a lot of time licking and chewing the genital area. If you notice your dog excessively mounting, licking or chewing himself, or rubbing his body against things, take him to a veterinarian to rule out medical concerns.

What to Do About Excessive Mounting and Masturbation

If you think your dog may become aggressive if you stop him from mounting other dogs, people or objects, do not attempt to do so. Instead, consult a qualified professional, such as a Certified Applied Animal Behaviorist (CAAB or Associate CAAB) or a board-certified veterinary behaviorist (Dip ACVB). If you can’t find a behaviorist in your area, you can seek help from a Certified Professional Dog Trainer (CPDT), but be sure to determine whether she or he has professional training and extensive experience successfully treating aggression. This type of expertise isn’t required for CPDT certification. Please read our article, Finding Professional Behavior Help, for information about finding one of these experts in your area.

Mounting During Play, in Response to Stress or for Sexual Reasons

• If your dog mounts infrequently (once or twice a day at most) and it isn’t bothersome to you, other people or other dogs, it’s not necessary to stop his behavior.
• If your dog’s mounting or masturbation does bother you, other people or other dogs, try to distract your dog. If you can, get his attention before he starts mounting or masturbating. Some dogs display amorous-looking behavior before mounting, so if your dog sidles up to something or someone and starts to pant, lick, whine, paw or rub against the person, dog or object, he may soon start to mount or hump. If you see your dog performing any of the behaviors above, or if you see him start to mount someone or something, toss a toy, play a game, give your dog a chewie, or ask him to perform some previously learned basic obedience skills or tricks that he enjoys (sit, down, shake, etc.).
• If you have an intact male dog, consider neutering him. Although neutering doesn’t always stop a dog from mounting or masturbating, it does reduce his sexual motivation—especially if the behavior is triggered by the presence of a female dog who’s in heat. Likewise, if you have an intact female dog, consider spaying her. It might reduce her motivation to hump other dogs, especially if she only mounts when she’s in heat or when she’s around other female dogs in heat. Spaying or neutering your dog has other benefits, too. It prevents the birth of unwanted puppies, and it helps prevent serious medical problems like mammary and testicular cancers.
• Be warned: If your dog mounts other dogs, he may get himself into trouble. Many dogs don’t like to be humped. They might take offense and start a fight with your “amorous” dog. If you have a hump-happy dog, you might want to teach him to leave other dogs alone when you ask him to. Once you’ve taught your dog what “leave it” means, you can start using it during his interaction with other dogs. Watch your dog carefully when he plays with his pals. As soon as you see him preparing to mount another dog tell him to “Leave it.” Remember to reward him if he does. If he doesn’t, end his play session and work on leave it without other dogs present for a while longer. If your dog habitually humps other dogs, you can also try teaching him to play games with you so that he’s less interested in other dogs. Tug and fetch are great!
• If your dog has developed a habit of mounting you or other people, discourage him from humping by pushing him off, turning away, sitting down or somehow adopting a position that prevents him from mounting. If your dog won’t stop, say “Nope!” and immediately take him to a quiet, safe room for a short time-out. (Make sure that there aren’t any fun toys for him to play with in the time-out area.) Leave your dog alone for one to three minutes. When the time-out is over, let your dog out and behave as if nothing happened. There’s no need to act like you’re angry. If your dog tries to mount again, repeat the sequence above and give your dog another time-out. If you have to give your dog a time-out more than a couple of times, you may start to have trouble catching your dog when you say “Nope!” If that’s the case, it will help to clip a lightweight two- to four-foot leash onto your dog’s collar and let him drag it around at home when you’re there to supervise him. Then you can pick up the leash when you need to take your dog to his time-out area. Be sure to remove the leash when you can’t supervise your dog so that it doesn’t accidentally get caught on furniture or get wrapped around your dog’s legs.
• Discouragement by itself won’t prevent mounting from reoccurring. You must also do some preventative training. You’ll need to teach your dog a behavior that he can perform instead of mounting when he’s around people—something that he can’t do while humping. Train him to sit on cue, for example. After your dog readily sits for a treat when you ask him to, you can start using that skill to discourage humping. As soon as you see your dog start to mount, say “Sit.” If he sits, praise him happily and reward him with a tasty treat. Then you can ask him to sit a few more times or perform other tricks he already knows. When your dog has performed some polite behaviors and calmed down a little, you can offer him few minutes of play with a favorite toy. This may alter your dog’s motivational state so that he’s no longer interested in humping. If the humping occurs in specific contexts, such as in response to exciting or chaotic interactions between people (hugging, greeting, arguing, etc.), ask your dog to sit and stay whenever you do the things that trigger his mounting behavior. Remember to reward your dog frequently if he behaves politely instead of mounting.
• If your dog only mounts when dealing with stressful situations (greeting new people, for example), avoid those situations whenever possible. If you can’t avoid a situation or thing that makes your dog anxious, try to reduce his stress as much as you can. For instance, if your dog finds visiting the veterinary clinic stressful, take him to the clinic for frequent social visits. During these trips to the vet’s office, give your dog plenty of tasty treats and make sure that nothing unpleasant happens. After a few weeks or months of occasional “cookie trips” to the vet’s office, your dog will start to enjoy going there. That change in his feelings will make future visits to the veterinary clinic much less stressful for him. If your dog becomes anxious when he greets new people, distract him when he encounters strangers so that the experience is less overwhelming for him. Try teaching your dog to sit for delicious goodies or fetch his favorite toy when new people visit your home.

Licking

• If your dog licks to stimulate himself infrequently (once or twice a day at most) and it isn’t bothersome to you, it’s not necessary to stop his behavior.
• If your dog’s licking behavior does bother you or causes irritation to his skin, try to distract him, preferably as soon as he starts to lick himself. Toss a toy, play a game, give your dog a chewie or ask him to perform some previously learned basic obedience skills or tricks that he enjoys (sit, down, shake, etc.). You can also try moving your dog to a different location.

Compulsive Mounting or Masturbation

• As soon as your dog starts to mount or masturbate, try to distract him. Toss a toy, play a game, give your dog a chewie or ask him to perform some previously learned basic obedience skills or tricks that he enjoys (for example, sit, down and paw).
• If your dog’s behavior has become compulsive and interferes with his normal daily life, you may need to get help from a qualified professional. Please read our article, Finding Professional Behavior Help, for information about locating a Certified Applied Animal Behaviorist (CAAB or Associate CAAB) or a board-certified veterinary behaviorist (Dip ACVB). If you can’t find a behaviorist in your area, you can seek help from a Certified Professional Dog Trainer (CPDT)—but be sure to determine whether she or he has professional or academic training and extensive experience treating compulsive behavior, as this expertise isn’t required for CPDT certification.
