Top 6 Reasons to Neuter Your Jack Russell Terrier

I’m a dedicated Jack Russell lover who’s trained, hand-raised, bred and bought Jack Russells.


There’s a lot of controversy when it comes to the subject of neutering animals. Many dog owners think that they should have a right to breed their pets if they so desire, or that neutering pets is somehow going against nature. In fact, neutering is good for both your pet and society in general.

Neutered Jack Russells are generally less aggressive and show less behavioral problems, they are less likely to escape from your home to go roaming, and they are less likely to develop certain cancers. So there are a few good reasons to have your dog neutered as soon as physically possible.

1. Neutering Helps Prevent Dog Overpopulation

In some parts of the world, Jack Russells are put down almost immediately when they come into pounds because there are simply too many Jack Russell strays. Millions of dogs are put down every year. There are simply too many dogs in the world, and breeding dogs without professional know-how is only going to add to this problem. This is closely related to the next benefit of neutering a Jack Russell.

2. Neutered Dogs Are Less Likely to Stray . . .

Jack Russells are notorious for escaping from even the most dog-tight backyards. Usually, this is because they are searching for a mate. Male dogs can pick up the smell of a female in heat from over a mile away. When a dog picks up that scent, it doesn’t make a difference how happy he is at home or how well you treat him—he will be out of there as soon as he gets a chance.

Ever noticed that your male Jack Russell has been particularly hyper for no apparent reason? This may be why. The situation is the same for females. When they come into heat, they become possessed. All they can think about is finding a mate, and they will also try to escape to find one.

3. . . . Which Makes Them Less Likely to Get Hit by a Car

Consider this statistic: 80 percent of dogs killed in car accidents are unneutered males. Combine this with another fact: The leading cause of death for Jack Russells is being hit by a car. When you consider these facts, I’m sure you can see why having your Jack Russell neutered is a great idea.

4. Neutered Dogs Are Less Likely to Die of Cancer

In males, castration can greatly reduce the risk of prostate and testicular cancer. In females, the risk of uterine and ovarian cancer is virtually eliminated. On average, dogs that are neutered live longer than dogs that aren’t.

5. Neutering Can Reduce Aggression Problems

This is particularly noticeable in male Jack Russells. Neutering significantly lowers the hormones that cause aggression in dogs, so having your Jack Russell neutered can get rid of or reduce problems such as biting and protectiveness over food and toys.

6. You Won’t Have to Deal With the Annoying Heat Cycle

For a female dog, when she is going through heat she will be showing her vulva to anyone and everyone who will take a look. If you’re not careful, you may end up with an unwanted litter of Pug Jack Russells on your hands! In many places, it’s illegal to take your dog into public places when she’s in heat. A Jack Russell that can’t go for a walk for three weeks while she’s in heat becomes one very hyperactive dog.

Not Comfortable With Surgical Neutering?

There is another option these days if you don’t want to have your dog irreversibly neutered. Chemical castration is a temporary solution that doesn’t alter the dog’s physicality permanently. It can be reversed if needed. This is ideal if you have a dog that you may want to show at some point in the future, but be aware that there are risks involved with chemical castration. Please seek more information from a veterinarian if you want to consider this option.

I had my JRT neutered as soon as he was old enough to have to done and he still got hit by a car. Because of his playful nature, he wanted to escape constantly and play with other dogs. He survived though and lives a full life.
