The right fit of your Gunner kennel is a key part of its 5 Star Crash Tested safety. Seth Bynum, DVM, weighs in from a vet's perspective on how to think about choosing the best crate size.

When it comes to maximizing your dog’s safety, the proper fit of your Gunner kennel is as important as its rugged, rotomolded construction. As a veterinarian, here is my TL;DR on choosing the best crate size for your dog:

  1. A good rule of thumb for estimating kennel fit is to choose a size that allows your dog to sit up and turn around with minimal effort. Anything larger than that would seem excessive from a dog’s perspective and a potentially dangerous one from a safety standpoint.

  2. A more snug fit between your pup and the kennel works much in the same way seatbelts and airbags do at helping slow down the dog before the stop.

Below I break down my reasons behind these recommendations:

The Physics Behind A Tight Fit

Without boring you with the underlying equation, the idea behind the physics at play in an accident is best summarized by a quote from writer Douglas Adams:

“It’s not the fall that kills you, it’s the sudden stop at the end.” – Douglas Adams

Scientists refer to this concept as the impulse, or the forces exerted on an object at impact. Naturally, the higher the impulse, the greater the risk of serious injury in an accident. 

The role of a kennel involves not only its ability to withstand the impact of a collision but also its utility in bringing your canine passenger from a high velocity to a stop as slowly as possible, thus minimizing the impulse forces imparted on your dog’s body. 

Perhaps more relatably, think of the walls of your Gunner kennel as your truck’s bumper and the interior space as the seatbelt and airbags. As rock-solid as they feel to the touch, the dynamic, flexible properties of the rotomolded plastic allows the kennel to slow down gradually, a quality best appreciated in slow-motion footage of crash tests. The kennel frame absorbs the impact of the collision, flexing and spreading the energy over a larger surface area while maintaining its structural integrity.

Additionally, the science suggests that the space between your dog and the interior wall of the kennel plays an equally important role in mitigating impulse. It’s worth pointing out that when a vehicle is traveling at highway speeds, so are all the objects within the vehicle, including your dog. In a sudden stop or accident, the vehicle slows rapidly, but the dog continues moving at the same velocity until other forces act on the dog to reduce its speed. 

“Double-wall construction essentially means double the impact protection (if not more) for the animal, as the exterior layer would absorb the majority of an initial impact, with the interior wall providing another layer of protection.” – Dr. Alvin Spence

By the same lengthy formula, the farther the distance the dog has to travel before coming into contact with the kennel wall, the greater the impulse generated in the pup’s collision with the kennel itself.  Simply, a more snug fit between your pup and the kennel works much in the same way seatbelts and airbags do at helping slow down the dog before the stop.

What A Veterinarian Thinks About Kennel Fit

I’m a veterinarian – definitely not a physicist – so I’m more comfortable relying on my understanding of canine behavior as it supports achieving a proper kennel fit as a biologically appropriate requirement in addition to a safety issue. 

As denning animals, our dogs come pre-programmed to embrace the sensation of tight quarters while resting or traveling. This natural inclination explains why my bird dogs feel more comfortable tucked in tightly in the space between my chair and ottoman as I write this instead of sprawled out in the open expanse of my office floor. 

It would be an error rooted in anthropomorphism to select the largest kennel for your dog based on your own personal preference for more elbow room. As much as I love to spread out in my king-sized bed, dogs neither crave nor benefit from the extra real estate found in an over-sized kennel.  

A good rule of thumb for estimating kennel fit is to choose a size that allows your dog to sit up and turn around with minimal effort. Anything larger than that would seem excessive from a dog’s perspective and a potentially dangerous one from a safety standpoint.

Be sure to take advantage of the numerous virtual tools Gunner has developed to assist you in finding the proper fit for your dog as well as your travel vehicle.  

Additionally, achieving a proper kennel fit doesn’t mean having to make compromises in comfort. If cush quarters are a priority in addition to safety – as is the case for me with my own dogs -– Gunner offers custom-fitted kennel mat and extra-thick orthopedic bed options, both of which I utilize on our multi-day hunting trips across the West.

It’s like an insurance plan….

This is by far the best kennel made. I use mine daily and they take lots of abuse. They never even seem to wear at all. Hose them off with soap and water and they look brand new. I encourage all of my puppy buyers to get them as well. It’s like an insurance plan for your best friend!

Wow, Just Wow

Wow, this kennel is the Yeti of dog kennels! everything about this kennel is first rate. Yes, there are cheaper, but none can compare to a Gunner kennel.

Amazing travel kennel

This thing is built like a tank. I have no doubt this will protect our little guy if we are ever involved in an accident. We recently completed an 800 mile road trip with him in the crate. It was well worth the money. This was the first time he was calm in the car and not whining. He slept easily during the drive. We felt calm know he was secure and comfortable. Cannot recommend this crate enough!!

Unlike any other crate I have seen

I purchased two Gunner kennels, a medium and a small, for my pups. Immediately, you understand this is a different level of product compared to what you’ve used before. The construction is fantastic and legitimately heavy duty. I feel so much better knowing I’ve done everything I can to keep my dogs safe in case of a worst case scenario.

Best purchase for my best friends

I’ve been buying cheap kennels for the four years I’ve owned my dogs, none of them seemed to hold up. I’ve wanted a Gunner for a year now, and the more I read stories of how they have saved dogs lives, it made me think of how losing my best friends would damn near **** me. So I made the purchase and will never look back. It is one solid kennel and I will not let the kennel hold me back from traveling farther to hunt anymore. It’s well worth the investment. I’m a firm believer in you get what you pay for, and this will not let anyone down.
