We often think that by neutering our pets we’re doing away with their sexual behaviour once and for all. And to a great extent, that is true. However, there are quite a lot of dogs who still seem “up for it” even long after their surgery… In this blog, we’re going to explore how and why!
Have you ever wondered if your furry friend can still “get busy” after that trip to the vet? It’s a common question many dog owners ask themselves, especially if they notice their neutered male dog still showing interest in females. Let’s dive deep into what happens after neutering and whether your dog can still tie.
What Does “Tying” Mean in Dogs?
Before we jump into the answer, let’s clarify what “tying” actually means. When dogs mate, the male’s penis swells inside the female’s vagina, causing them to become temporarily locked together—or “tied.” This natural phenomenon helps ensure successful fertilization by keeping the male’s sperm deep inside the female’s reproductive tract.
The Short Answer: Yes, They Can!
Yes a neutered male dog can still tie with a female dog.
This might surprise some pet parents, but neutering doesn’t remove your dog’s ability to physically tie with a female. The procedure removes the testicles but leaves the penis and its associated structures intact This means your neutered buddy still has the equipment needed to lock with a female dog
Why Can Neutered Dogs Still Tie?
When a male dog undergoes neutering (also called castration), the vet removes his testicles, which are the main source of testosterone and sperm production. However:
- The penis and its suspensory ligaments remain intact
- The physical mechanisms that cause the penis to swell during mating are still present
- The ejaculatory reflex remains functional, even though there’s no sperm in the ejaculate
Think of it like unplugging the printer but leaving the computer and its software intact—the hardware is still there, but it’s not producing the same output.
Will a Neutered Dog Still Try to Mate?
This is where things get interesting. Some neutered dogs still show interest in mating, while others lose interest completely. It depends on several factors:
1. When Your Dog Was Neutered
Age matters tremendously. Dogs neutered before reaching sexual maturity (around 6 months) are less likely to develop sexual behaviors or maintain interest in females. Their brains never fully develop those sexual pathways.
Dogs neutered after sexual maturity have already established those brain patterns and learned behaviors related to mating. They’re more likely to:
- Be attracted to females in heat
- Attempt to mount and mate
- Continue marking territory
2. Residual Hormones
Even after neutering, your dog still produces small amounts of testosterone from his adrenal glands. For some dogs, this residual hormone is enough to maintain some sexual behaviors.
3. Established Behaviors
Dogs are creatures of habit. If your dog regularly mated before neutering, he might continue the behavior afterward simply because it’s what he’s used to doing—even without the hormonal drive behind it.
Can a Neutered Dog Still Get a Female Pregnant?
Here’s the good news: while a neutered dog can still physically tie with a female, he cannot impregnate her—with one important exception.
Important warning: Sperm can remain viable in your dog’s reproductive tract for up to 30 days after neutering! Some experts believe this window might be even longer—up to 8 weeks.
So if you’ve just had your dog neutered, keep him away from females in heat for at least 8 weeks to be absolutely safe.
Why Does My Neutered Dog Still Try to Mate?
If your neutered dog is still attempting to mount females (or other dogs, people, or objects), there are several possible explanations:
- Recent neutering: His hormone levels haven’t fully dropped yet
- Habit: He’s continuing a behavior he learned before neutering
- Dominance display: Mounting can be about showing dominance, not just mating
- Play behavior: Some dogs mount during play
- Excitement or stress: Some dogs mount when overly excited or anxious
Will a Neutered Male Dog Still Be Attracted to a Female in Heat?
Yes, some neutered males will still be attracted to females in heat. Female dogs release powerful pheromones when in heat that can be detected from great distances. Your neutered dog might:
- Become restless
- Try to escape to find the female
- Whine or howl
- Lose interest in food
- Become fixated on the scent
This attraction is typically stronger in dogs neutered after sexual maturity and can vary greatly depending on the individual dog’s personality and history.
Can a Neutered Dog Lock with a Spayed Female?
Yes, a neutered dog can still lock with a spayed female. The physical mechanism for locking remains intact in both animals, even though neither can reproduce. However, this is less common since spayed females don’t go into heat and therefore don’t produce the hormones that typically trigger mating behavior.
How to Prevent Your Neutered Dog from Tying
If you’re concerned about your neutered dog trying to mate or tie, here are some practical solutions:
- Keep him away from females in heat: This is the most effective approach
- Use a belly band: These are like diapers for male dogs and can prevent mounting
- Try calming pheromone products: Products designed to reduce mounting behaviors
- Training: Consistent commands to interrupt mounting behavior
- Supervision: Don’t leave your dog unsupervised with females
Common Myths About Neutering and Sexual Behavior
Let’s clear up some misconceptions:
| Myth | Reality |
|---|---|
| Neutering immediately stops all sexual behavior | Hormones take time to leave the system, and learned behaviors may continue |
| Neutered dogs can’t physically mate | They can still mount and tie, just without fertile sperm |
| Neutering will fix all behavioral problems | While it helps with some issues, training is still necessary |
| Neutering is painful for dogs | Modern procedures include pain management to keep pets comfortable |
Benefits of Neutering Beyond Preventing Reproduction
While we’re on the topic, let’s remember the many benefits of neutering your male dog:
- Prevents testicular cancer
- Reduces risk of prostate problems
- May reduce aggression in some dogs
- Decreases roaming behavior
- Reduces marking territory with urine
- Helps control pet overpopulation
When to Consult Your Vet
If your neutered dog’s mating behaviors are concerning or problematic, consider talking with your veterinarian, especially if:
- The behavior started suddenly after a period of not showing interest
- The behavior seems compulsive or obsessive
- Your dog is injuring himself or others with mounting attempts
- The behavior is disrupting your household
Final Thoughts
A neutered dog can definitely still tie with a female, but he cannot father puppies (after that initial post-surgery period). Whether he’ll want to mate depends largely on when he was neutered and his individual personality.
Understanding this aspect of your dog’s behavior helps you manage expectations and prepare for any situations that might arise. With proper training, supervision, and patience, you can help your neutered dog lead a happy, healthy life—with or without his romantic inclinations.

The male however is different
The drive to mount and thrust, or hump, seems to be triggered by hormones at puberty (although see below!). But once triggered, it may become a self-reinforcing behaviour. Essentially, once dogs learn how to do it, they want to carry on doing it. Presumably, because it’s “fun” or otherwise rewarding, even in the absence of high testosterone levels.
Can neutered dogs have puppies?
In order for puppies to be produced, two dogs would have to mate, neither of whom had been neutered. If one has been neutered but not the other, a puppy will not be produced. They are however still capable of spreading sexually transmitted infections. If you are worried your female may be pregnant or have a sexually transmitted infection, please contact your local veterinary practice as soon as possible. A pregnancy scan can be used to detect puppies if you are suspicious. Bear in mind that an entire female dog kept only with a castrated male can still get pregnant – just by a visitor, not by her housemate.

What does it mean if a dog is neutered?
Firstly, let’s define what we mean by “neutered.” Neutering refers to the surgical procedure where a male dog’s testicles are removed in order to prevent them from producing sperm and reduce testosterone levels. This results in an inability to impregnate females and usually leads to reduced sexual behaviors like mounting.

Can a neutered dog still mount a female?
A neutered male dog typically cannot impregnate a female as sperm production ceases after neutering. However, mounting and even copulatory tie can still occur due to residual hormones or learned behavior. The risk of pregnancy is extremely low but not impossible if neutering was recent or incomplete.
