How do I stop my Yorkie from constantly humping our new puppy?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Humping isn't always sexual in nature, dogs can hump to show dominance or from anxiety. All this is very new for Cubby. It has only been one day and he will need time to acclimate. I would always keep Cubby leased to an adult and when he starts getting rough, make him sit or lay down and give him a treat. Consider the muzzle gentle leader to control him better. Be sure to provide adequate exercise and play with Cubby. They can be jealous about how affection is given. If the behavior doesn't start to calm down I would call your Vet monday for temporary "doggie downers" to calm him. I hope this helps and I wish everyone the very best!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear you are having this problem. Not sure what sex the Boston is but either male or female, fixed or not fixed, humping behavior by other dogs is a way of expressing dominance and most times has nothing to do with mating behavior. If it doesn't escalate into a fight, I would advise letting it occur and let the two dogs would out the dominant submissive game that is playing out. Again, I would separate them when you are not there, crating the dogs to prevent soiling of the rooms if you have to. Otherwise seek advice from your veterinarian. They may want to see both dogs and advise you from there. Older dogs can undergo neutering and do need blood work before considering that option. But remember even sterilized dogs will exhibit humping behavior to determine the order of the pack. I hope this helps and good luck

He is at the age of puberty! The fastest way to stop puberty behavior is to have him neutered. He is young enough it can stop a lot of unwanted behaviors such as humping and urinated excessively by marking and lifting his leg. It will not help humping as a result of dominance. This how dogs show one another who is in charge. So if he is doing to it to some people and not others, then he is proving he is charge of them and does not respect (listen) to them. The best way to correct this is to encourage training sessions to make him obey and listen so he understands he is not in charge and that behavior is unacceptable.

This definitely can be happening because Buddy is feeling uncomfortable. I would continue to have monitored meet and greet sessions, and if someone becomes too nervous or starts to try humping behavior, separate and let both dogs relax. Sometimes, dogs do well with mutual activities such as a walk or running around a backyard as this can help them focus on something else (the walk) instead of focusing entirely on the other dog. This may also help nervous dogs calm down a little by changing their focus. It does take time for dogs to get used to each other, so keeping up with the meet and greets, adding in a mutual activity, and providing places for both dogs to go and relax on their own without the other bothering them is best. I would not discipline the behavior, especially if your dogs are trying to communicate their needs to each other, and instead just calmly separate, allow them to calm down, and then reintroduce.

This is not a sexual behavior, but likely a response to stress, anxiety or to assert his dominance. Correct the behavior immediately when you see it. Remove him from the dog with a stern "No" and offer a toy or task to distract him. Praise and reward him when he complies. If he persists, separate him until he settles down. Be firm and be consistent.

This is a very normal behavior, espeically in an uneutered male puppy. If it bothers you I would recommend reading this article: https://drsophiayin.com/blog/entry/poodles_embarrassing_greeting_behavior/ by veterinary behaviorist Dr. Sophia Yin which gives detailed recommendation on how to treat this issue.

Humping is a common play behavior in both puppies and older dogs, not abnormal at all :) Many dogs don't appreciate being on the receiving end of this behavior, so I would try to redirect Kuro to something else if he gets excited and begins humping your other dog during play. Over time, as he develops better canine social skills, this behavior should become less frequent. Your other dog may also growl or snap at him when he does this, which is okay as long as he doesn't hurt Kuro - this is how puppies learn what's acceptable and what isn't.
