Although it is designed to offer all-around protection, the muzzle is loose around the JRT’s mouth, allowing them to drink and pant normally. However, the straps are too short when using the muzzle with bigger JRTs.

Features to Consider in the Best Muzzle for Jack Russell 

Jack Russell’s muzzles from different manufacturers vary in build quality, size, breathability, and weight. Keeping in mind that the level of aggression and size of JRTs varies across the breed, you should consider the following things when choosing a muzzle that will suit your dog.

The following table further breaks down these features for easier digestion.

Jack Russells are energetic and playful dogs that love running around, and a muzzle is unlikely to stop this behavior. If the muzzle is not well padded, these activities make the muzzle rub against the dog’s skin, causing irritation. Some of the signs that the muzzle is causing discomfort in your dog include:

  • Rubbing or hitting on different objects such as furniture using the muzzle to try and take it off
  • The dog rubbing or hitting its face against the ground when you wear the muzzle
  • Itchiness that makes the dog paw its face after wearing the muzzle

Therefore, it is advisable to go for a comfortable and well-padded muzzle such as the neoprene-padded The Company of Animals Baskerville Ultra Dog Muzzle. However, remember that JRTs are intelligent dogs and have a strong prey drive, and will want to chase and catch other pets.

That means a JRT can understand that the muzzle will prevent it from catching and biting other pets and be unwilling to wear it. Before discrediting the muzzle, you should consider whether the dog refuses to wear it due to discomfort or lack of proper training. 


JRTs can be aggressive and might end up biting on the muzzle itself. You will need to ensure the muzzle is constructed of food-grade materials that pose no health risks to your dog.

The material should also be sturdy enough to withstand the biting while not so hard to damage the dog’s teeth. Therefore, it is advisable to go for a muzzle constructed of a malleable food-grade material such as the thermoplastic rubber construction of The Company of Animals Baskerville Ultra Dog Muzzle.


Although many people overlook the breathability of a dog muzzle, it is one of the most critical features to consider, especially due to the hyper nature of JRTs. These dogs are energetic and tend to engage in rigorous exercises that help them burn calories and use up excessive energy.

JRTs are also double-coated dogs and might not be able to lose heat effectively through their bodies like their single-coated counterparts. Typically, lack of good airflow can be an issue during summer or warm weather when there is high humidity and low oxygen level.

Therefore, it is advisable to go for a muzzle constructed of a breathable material such as the Oxford fabric construction in the CooZero Anti-Biting Dog Muzzle. This material has good airflow and will allow your dog to breathe and pant normally.

Mouth Movement

Different dog muzzles have different abilities to restrict mouth movement. In most cases, the extent to which the muzzle should restrict the dog’s mouth movement will depend on individual preferences.

For instance, if you have small children in your home or your dog is excessively aggressive, you can go for a muzzle such as the BronzeDog Wire Basket that only prevents biting yet allows the dog to do everything else freely and normally.

On the other hand, you can go for a more restrictive muzzle such as the PetSafe Muzzle if you are carrying the dog in a car and you don’t want it to vomit in the car, or you are with your dog in a park or place where barking is not allowed.


Keeping in mind that JRTs are relatively small dogs, it is important to consider the weight of the muzzle. Since the dog’s nose will mainly hold the muzzle, you don’t want a muzzle that will exhaust your dog and prevent it from engaging in regular play and fun.

In most cases, the muzzle that weighs more than 5 ounces might be heavy for a JRT, and weight might make the dog unwilling to wear the muzzle in the future. Therefore, it is advisable to go for a lightweight muzzle such as the Nylon constructed PetSafe Muzzle.

Although it is advisable to measure the snout of a JRT before deciding on the right muzzle size, the snout size might change, especially if the dog is still growing. There can also be snout size and weight changes even for adult JRTs due to changes in diet, exercise levels, or health conditions.

That means you will need to get another muzzle if you’re dealing with fixed-size muzzles. The best way to avoid this problem is to get a versatile muzzle with adjustable straps, such as the BronzeDog Wire Basket.

The adjustable straps allow the muzzle to fit comfortably without exerting excessive pressure or slipping out. If you want a muzzle that can serve your JRT from puppyhood to adulthood, you can go for the CooZero Anti-Biting Dog Muzzle, as it comes in several pieces that can fit dogs of varying ages.

Frequently Asked Questions

Can My JRT Swim With Its Muzzle On?

Technically a JRT can swim with its muzzle on if the muzzle design is more of a wire or rubber basket like the Company of Animals Baskerville Ultra Dog Muzzle, as it will allow sufficient airflow.

However, considering that most muzzles will limit the airflow, letting your dog swim with a muzzle on is not advisable.

Can I Leave My JRT With a Muzzle All Day?

Yes, you can leave your JRT with a muzzle all day if the muzzle has good airflow and allows the dog to breathe and pant freely. However, even the most lightweight muzzle can exhaust a small dog like a JRT, so leaving it with a muzzle for more than 8 hours is not advisable.

Can a Muzzle Stop My JRT From Being Aggressive?

A muzzle cannot stop a JRT from being aggressive, as aggression in JRTs is more of a natural behavioral issue. The introduction of muzzles might even make them more aggressive.

However, muzzles help eliminate the risks associated with aggression, such as biting other people or pets.

Final Thoughts

The best muzzle for Jack Russell should allow sufficient airflow so the dog can breathe and pant freely. The material should be sturdy enough to withstand biting even from the most aggressive JRT. The above muzzles are high-quality and versatile and can fit dogs of varying ages.
