A pregnant dog humps due to hormonal shifts, stress, excitement, or boredom, similar to non-pregnant dogs, but pregnancy can heighten these feelings, leading to increased mounting as a coping mechanism for physical discomfort, anxiety about the upcoming birth, or pent-up energy. Changes in body chemistry and increased nesting instincts can make her restless or overstimulated, causing her to hump objects, people, or other pets to relieve tension, seek attention, or express excitement.
Pregnant Dog Humping Behavior: What It Means Pregnant dogs may show unusual behaviors like increased restlessness or nesting instincts. Humping in pregnant dogs is often a behavioral response unrelated to fertility status. It can indicate excitement, stress, or a way to relieve discomfort.
That being said, I wouldn't let her hump freely. If the pup is doing something directly to the other dog, like adult dog is laying down, and here comes pup trying to deebo her out of her spot. In that case I would let the adult dog put her in her place. If she does that by humping, fine.
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.
A red flag dog behavior signals deep fear, stress, or potential aggression, going beyond normal misbehavior, and includes intense growling/snapping without cause, sudden aggression in a calm dog, persistent hiding, resource guarding (food aggression), freezing, destructive behavior linked to separation anxiety, or signs of extreme anxiety like trembling, lip-licking, and tail-tucking, indicating underlying problems needing professional intervention.
Humping is frequently seen as a response to stress, anxiety, frustration, excitement, over-arousal and/or a lack of social skills. Humping is seen in both males and females, altered and unaltered dogs, and at different ages.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, representing 3 days (overwhelmed/hiding), 3 weeks (settling in/testing boundaries), and 3 months (feeling at home/bonding) to help owners manage expectations and provide patience, routine, and a calm environment, understanding that anxiety is normal as they decompress from a stressful past. It's a framework for recognizing stress and fostering trust, not a rigid timeline, but it helps owners understand why a new dog might seem timid or act out initially.
By now you know that dogs lick people's crotches or smell crotches for a variety of reasons. Our genitals, like our feet, armpits, mouths, etc. hold the most scents, bacteria, and pheromones.
When a dog mounts another animal, it typically is caused by either arousal, anxiety, or play. Intact males and intact, “in-heat” females often display inappropriate mounting, reaffirming the potential role of sex hormones in this behavior.
Nesting Behavior
As the pregnancy progresses, many dogs may seek quiet, secluded areas to create a comfortable space for their upcoming puppies. This instinctive behavior can include rearranging bedding or attempting to gather items like blankets or toys to create a nesting area.
Five key warning signs during pregnancy needing immediate medical attention include vaginal bleeding, severe headaches with vision changes, decreased baby movement, severe abdominal pain/cramping, and signs of preterm labor like regular contractions or fluid leakage, as these can signal serious issues like miscarriage, preeclampsia, placental problems, or infection. Always contact your healthcare provider or seek emergency care for these symptoms.
Excitement – if a dog is over excited, or very energetic, mounting and humping can help get rid of excess energy. Stress – some dogs mount or hump to relieve stress and anxiety. Medical problems – a dog may mount and rub against an object if they have itchy skin, which can sometimes lead to humping.
Once an animal is neutered, it loses its ability to reproduce due to the removal of reproductive organs. However, this doesn't mean all sexual behaviors stop right away. It takes some time for their hormone levels to decrease after surgery, which means they might still try to mate soon after being neutered.
You might ask yourself, Why does a female dog hump after being spayed? It can take as many as three months for a female dog's hormones to leave her body after being spayed. Remaining hormones may be the culprit for continued humping from your female pup after being spayed or neutered.
A dog's humping behavior can begin in puppies 3–6 week of age, most commonly during play. Both male and female puppies may mount each other. Mounting can also occur when adult dogs play with another dog or person.
Dogs may sniff at crotches if you recently have had sexual intercourse, gave birth, or are menstruating, which can cause you to give off a higher level of pheromones. Even if a dog is familiar with a person, if that person is menstruating or just had a baby, they are letting off a different smell.
If more air passes through their nose they have more chance to pick up smells. How far dogs can smell depends on many things, such as the wind and the type of scent. Under perfect conditions, they have been reported to smell objects or people as far as 20km away.
Pheromones and Communication
They are crucial in communication and social interaction among animals, including dogs. It is believed that menstrual blood may contain pheromones or other chemical cues that dogs find intriguing or stimulating.
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles. Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
The 777 Puppy Rule (or Rule of 7s) is a guideline for puppy socialization, suggesting that by seven weeks old, a puppy should experience seven different Surfaces, seven different Sounds, seven different Objects, seven different People, seven different Locations, seven different Containers, and seven different Challenges, all in positive, short, and safe ways to build confidence and resilience. It helps prevent fear and reactivity by creating positive associations with novel experiences during the critical socialization window (around 4-16 weeks).
Keep introductions short by following the “three second rule”; count to three as the dogs sniff each other, say thanks or nice to meet you to the owner, and then excitedly call your dog away and continue your walk.
Subtle signs your dog might be stressed include:
This can be the case whether the dog is humping another dog, a person, or even a toy. But dominance isn't the only explanation—sometimes, dogs hump when they're overstimulated, excited, stressed, or unsure of how to cope with their energy in the moment.
Once he's ejaculated, the two dogs may temporarily become physically locked together in a 'breeding tie'. If you haven't seen this before then it may seem strange, but it's perfectly natural and is a part of how dogs mate, so it's nothing to be worried about.
Offspring from a mother-son mating would, therefore, have a 25% chance of inheriting two bad copies of the mutations that have been passed down to the son. This is a greater than 100-fold risk compared to an outbred dog! Inbreeding in dogs has real consequences.
