Why does my dog do that? : Mounting

    Nothing can be more embarrassing than your dog mounting other dogs (or even people!), but did you know that this is a normal canine behavior? Dogs mount in play as play is practice of future behaviors and excessive mounting in pubertal males is normal. Most people are familiar with such causes as sexual behavior and mounting used to express dominance (ie their position at the top of the hierarchy), but there are other causes, and for successful treatment the root cause must be determined.

    Less commonly, the cause of being mounted may be a medical problem such as testicular cancer or even giving certain medications; so for this reason, the first step is to have your dog examined by their veterinarian. Males and females may mount females in heat. Females in heat may mount inexperienced males. Other dogs that have been in contact with females in heat and smell like them may also be mounted. One of the more common reasons for mounting is when a dog is excited or over-stimulated and mounting is used as a way to relieve this excitement or anxiety. For example, your dog may mount or be mounted when they enter a dog park, when unfamiliar people come to your house, or when petted too much. Over time dogs may learn that mounting is a very self-rewarding behavior and people usually encourage the behavior by paying lots of attention to the dog (even if the attention is negative) when they perform the behavior. Behavior that is rewarded is likely to be repeated.

    Studies show that two-thirds of male dogs show a decrease in mounting after neutering. Once medical conditions have been ruled out and your dog is spayed or neutered; the next step is implementing an appropriate behavior modification plan.

    The first step in behavior modification is to avoid the situation in which the behavior occurs, so that the dog does not continue to practice the behavior. For example, if your dog mounts other dogs at the park, then they likely need a break from the park, at least for now. If a dog is continually put in the situation that elicits the negative behavior, then it is very difficult to re-introduce the situation in a controlled manner to decrease the behavior. A board-certified Veterinary Behaviorist can help to design a plan specific to your family’s individual circumstances to diminish the undesirable behavior. This may include implementing a program in which the dog works for everything in life that they want (to give the dogs structure and predictability in their life, set the owner up as a positive leader, and increase their responsiveness to commands), teaching commands that are incompatible with the unwanted behavior (such as eye contact and hand target), the use of tools such as a head collar for better control, and desensitization and counter-conditioning (DS/CC) exercises. DS/CC is the primary technique we use to change your pet’s emotional response to triggers of anxiety and arousal.

  1. I would like to know more about how to use the DS/CC to treat this. My boy has a problem of getting over excited and his way of greeting dogs seems to be mounting them which is obviously not the best doggie greeting. I would like to teach him more appropriate dog greetings. He is very clicker trained (and highly food motivated) so if you can explain how to use the DS/CC I would love some suggestions.
    Thank you!!!

  2. My female 18 month old poodle x shitzu “mounts” her bed and/or stuffed toy. Is this a sexual behaviour? She was desexed at approximately 6 months.

    Thanks for the questions and comments!

    Ann- Clicker training is great. There are different ways to do DS/CC, even with the same situation. In general we start with the dog calm and relaxed and gradually make the situation harder as long as the dog remains calm. I often teach the dog to focus on the owner and look to them for guidance while being rewarded with treats. I would love to see you and your dog for an appointment so that we can make a specific plan for him!

    Sue- Mounting toys can definitely be a normal behavior in this situation, as long as it’s not causing other problems.

    Please do not hesitate to contact me with other questions.
