Humping or mounting is a behaviour that many dog owners find frustrating or embarrassing, but it is rarely sexual in nature. The key to stopping it is understanding why your dog is doing it.

Why Dogs Hump

Dogs may hump objects, other animals, or even people for several reasons. Common triggers include:

• Anxiety or arousal

• Self-soothing or displacement behaviour

• Attention-seeking

• Play

• Sexual behaviour (less common)

• Dominance (rarely)

If humping is left unchecked, it can become habitual, and in some dogs a compulsive behaviour. Puppies that are encouraged to hump may continue the habit into adulthood.

Anxiety or Arousal

The most common reason dogs hump is anxiety or emotional arousal. Think of it as a self-soothing behaviour, similar to how a child might suck their thumb. It helps dogs relieve tension and reset when they are feeling overwhelmed.

For example, imagine a dog at a busy backyard BBQ. If they have never seen so many guests before, they may feel overstimulated and hump the nearest person’s leg. If this gets laughs or pats, the dog may see it as a reward and repeat the behaviour.

Attention-Seeking

Humping can also be an attention-seeking behaviour. Puppies often start humping during play with toys, other pets, or humans. If they get laughter or engagement from people, they may see humping as a fun game that earns attention.

Play

For puppies, humping can be a normal part of play and learning. Just like children mimic adult behaviours in play, puppies use behaviours like stalking, pouncing, chasing, and humping to develop coordination, strength, and social skills.

Sexual Behaviour

Sexual mounting is less common but can occur in dogs over 9 months of age. Even desexed males may attempt to mount a female in heat. Sexual motivation is usually not the main driver of everyday humping behaviour.

Dominance

The idea that humping is about dominance is often misunderstood. Most humping is not about asserting control. In cases where a dog humps a specific dog repeatedly, it may reflect a social hierarchy. Ignoring the behaviour is usually sufficient.

How to Stop Humping

Here are practical ways to discourage humping in your dog:

1. Ignore it – If your puppy humps you, turn away and walk off. Pushing them down can reinforce the behaviour because they get attention.

2. Rule out medical issues – Sudden humping may be due to irritation around the genital or anal areas. A vet check can identify underlying problems, such as skin inflammation, infections, or parasites.

3. Redirect attention – If your dog humps visitors, redirect them to calm behaviour, for example, ask them to sit for a treat before greeting people. This helps reset their excitement.

4. Watch for anxiety signs – Dogs who hump under stress may also:

   • Be hyper-vigilant or constantly scanning their environment

   • Jump or startle easily

   • Avoid direct eye contact

   • Show pinned-back ears, tucked tail, lip licking, or exaggerated yawns

   • Pant, drool, whine, or shake excessively

   • Hide or retreat from situations

Addressing the underlying anxiety is often essential to reducing humping in the long term.
