Last Updated on June, 2024

English Mastiffs are Giant dog breeds known for their supreme strength. The average weight of a fully grown Mastiff usually exceeds 120 pounds, so it is not easy to find crates strong enough to keep your Mastiff safe effectively.

Although not aggressive, their bulky build requires you to get them the best crates that money can buy. 

In this Best Dog Crate for Mastiff article, I have reviewed five crates suitable for an English Mastiff and a buyer’s guide to help you compare and decide.

6 Best Dog Crates for a Mastiff

1. Impact Collapsible Dog Crate

All Mastiff owners out there, make a note when I say the Impact Collapsible dog crate is one of the highly rated dog crates for Mastiffs and the best for your Mastiff.

Based on what you read in this review, I bet you’ll agree with me. 

So you must wonder how a collapsible crate can hold a massive dog like a Mastiff. Uhm…but it can.

The Impact Collapsible is nothing like any of the regular collapsible crates you are considering. And here’s why it’s the best choice for your Mastiff…

This feature will impress you greatly: you can assemble or fold the crate in just under 60 seconds. I mean, like, is that even possible? Well, with Impact, IT IS. The crate is designed in such a way as to ensure hassle-free use by pet owners.

Oh, BTW, the setting up doesn’t require any tools, just a few twists and turns to secure joints, again proving it’s hassle-free.

Answering that lingering doubt of yours, No, the collapsible nature of the crate does not in any way compromise the strength and sturdiness of it. 

To achieve outstanding quality, the crate is made of solid aluminum sheets to hold even the toughest dogs, but at the same time, it is lightweight to allow convenient portability during your travels. Airline travel too.

The airline bars add strength and hold the crate structure strong. 

These mastiff crates have a ventilation system on all four wallsallowing maximum air circulation to ensure your dog is happy and safe.

These ventilation holes give you good visibility to keep an eye on your dog, and your dog also can watch the surroundings.

The featured slam latch allows single-handed opening and closure for convenience, while the lock and key system on top of the slam latch make it an escape-proof crate.

It also comes in handy for extra protection if your pooch has to leave your sight, like during air travel. 

These crates for mastiffs have stackable corners that allow you to stack them upon others, like cages, without any stability issues to save ground space.

They have three spring-loaded, ergonomic handles that are military grade to move even a large dog like a Mastiff easily.

Ideally, a 48″ size will work just fine for your big dog.

Doesn’t this crate have all the features you expect from the best Mastiff crates?

Key Features:

  • It takes less than a minute to expand or fold and doesn’t require any tools. 
  • The airline rails add structural support to improve stability to prevent possible collapse. Also, the rails make it IATA-approved.

Buyer’s Guide: Choosing the Best Crate for Your Mastiff

Picking a dog crate is not something you do just once in your dog’s lifetime. It has to be upgraded a few times as your dog grows up to ensure the crate is just the perfect size for your dog.

And to choose the right crate for your dog, you have to compare and contrast it with other crates you are interested in. Below are important factors that should be included in your evaluation.

Dog Crate Types Against Dog Nature

Dog crates come in many different types. You have to explore your options and decide if the crate can withstand your dog’s nature. Crate types include;

You must evaluate if your dog will chew into the wooden crates or easily destroy a plastic crate. For an English Mastiff Adult dog, a heavy-duty metal crate like the Impact Collapsible crate will be suitable to contain the dog effectively. 

See our overall best cages here.

The Crate Model Should Align the Purchase Intent

You have options in crate models like high anxiety, collapsible and stationary crates.

You have to choose a crate model that suits your lifestyle and, at the same time, accommodates your dog’s nature.

So for that, you have to figure out your primary purchase intent; is the crate for daily use or for vet visits or for long-distance travel, etc.

For example, if you travel often, the Impact collapsible crate is ideal as it is IATA approved. And it is excellent for daily use too.

But if you go for a stationary crate, you need something else to suit your travel needs.

Size of the Crate

Picking the right dog crate can be challenging because the crate size has to be upgraded a few times throughout your dog’s lifetime to fit your dog’s size during its different growth phases.

The general rule for crate sizing goes as follows: a dog should be comfortable enough to lie down, stand up, and turn around without hitting the roof or the side walls.

Going by that, an Adult mastiff will comfortably fit into a 47″- 50″ length size dog crate. But I recommend you check your dog’s correct crate size using our crate sizing guide.

Other Factors

Look for the features below to ensure improved overall functionality with minimal hassle.

Ventilation & Visibility

The ventilation system of any crate contributes to the visibility. Ventilation is important to ensure a continuous supply of fresh air to keep your dog comfortable and disturb visibility.

Durable Quality

Despite the crate type you choose, the materials used to build the crate should be high quality to ensure a strong and sturdy substructure.

At the same time, look for finishing details like riveted or welded joints, weather-resistant coatings, etc., to ensure reliable use over a long time.

What matters is that the crate you choose should be able to effectively withstand the hard and rugged use you expect out of a large and bulky dog like a Mastiff. 

Ease of Use

For feasible storage, portability, and transportation, go for a crate with ergonomic handles, casters, or wheels and easy to assemble or fold.

Ensure the crate has a removable slide-in tray for easy cleaning and maintenance. Also, a double-door dog crate will be great to ensure easy access in and out.

Crate Training Tips for a Mastiff

Following the do’s and don’ts below will optimize your as well as your dog’s experience with the crate;

  1. Never use the crate as a ‘time out option
  2. Use positive reinforcement when crate training
  3. Be mindful of leaving mastiff puppies unsupervised for more than 2 hours
  4. When your Mastiff is crate trained, give it the freedom to choose when it wants to go in the crate, and you can gradually introduce the dog bowl into the crate,
  5. Place the kennel preferably in an area where you and your family spend the most time
  6. Keep your Mastiff happy and comfy with pillows and a blanket.

Frequently Asked Questions

It is not recommended to leave a Mastiff puppy in a crate unsupervised for more than 2 hours. For an adult Mastiff, it is safe to leave them in the crate for up to 4-6 hours with periodic supervision.

You should start crate training your Mastiff puppy when it comes home for the first time. This is an opportune time to introduce physical boundaries and establish rules in the new environment.

Crate training your Mastiff can help with potty training, manage bad behavior, and ensure house rules are followed, providing benefits to both pet and owner.

In Conclusion

My choice for the best Mastiff crates is the Impact Collapsible crates that cover almost all that you would expect from an excellent quality crate. Not many crates can fall on par with this crate. 

It offers much versatility from the collapsing nature to thin yet strong aluminum sheet construction that keeps it lightweight but strong at the same time to air travel-friendly features and everything in between.

This crate will check off all the boxes on your checklist.

Overall, I hope this review helped you make the best choice for your Mastiff.
