About personalisation

Important - Creating your unique look with our bespoke stitching/engraving quality could take us up to 5 working days to complete, it's well worth the wait though.

When customising the Combat Range, the adjuster may cover part of the text. The best way to help avoid this is to choose the smallest size which will fit your dog; the adjuster will then be located at the end of the collar away from the name.

Preview images are for illustration only, text and Icons will always be centered neatly on the product. Colours and fonts may change very slightly during production.

We offer personalisation option on almost all of our Collars, Leads and Harnesses. What are the key benefits of adding personalisation to your BullyBillows gear?

1. They're unique to you and your dog.

2. If you have multiple dogs, adding your dogs name can help to distinguish which collar is for which dog.

3. Adding a phone number and Social handle in the unfortunate event of your dog getting lost, this is a very powerful way to ensure your dog can be tracked back to you.

4. If you have a working dog, nervous dog or one who just loves to jump, you can enter names such as POLICE DOG, WARNING, DO NOT PET, NERVOUS etc.

The chest measurement of your dog, or the girth, is the first measurement you’ll need to take. This can be taken by placing the measuring tape around the widest part of your dog’s torso, usually just behind the front legs.

The next measurement should be taken around the lower part of your dog’s neck, simply measure the widest part at the base of the neck as this is where the harness is going to sit. This size chart is based on min-max measurements.

Overall rating: 4.9 / 5 from 130 reviews.

Have tried numerous harnesses on both my current and previous dogs and all being bull breeds it can be hard to find good quality harnesses that fit. Having seen dogs out in the bully billows harnesses I decided to have a look at their website. There are quite a few to choose from along with a good colour choice. I opted for the tri harness as I wanted one to use with a long line aswel as every day use. It is perfect for my boy. I would also like to mention customer services especially Melody who was quick to reply, knowledgeable and very friendly.

I have a large adult male Labrador that pulls me quite a lot whilst on walks and this harness has been the best one iv ever used. I wish I’d gotten one sooner it fits lovely doesn’t constrict the dog at all or stop natural movement I love it plus the colours are awesome would defiantly recommend to anyone thinking of purchasing!

Bought this for my Shar-Pei. He's recently been rehomed with me and I've found he's quite strong on the lead when it comes to walks and more importantly when he sees another dog! I therefore needed something a bit sturdier and that didn't rotate completely around his body. This works so much better than the previous harness I had, plus it looks very smart!

Customer photo review of TRI-Harness® | Anti-Pull, Adjustable & Durable - Dog Trainers Choice - Light Blue v2.0

Very well made! The metal D rings are sturdy. There's two layers of nylon and a neoprene like padding on the interior for comfort and control. Very adjustable and versatile! The adjustable sliding parts are metal instead of plastic. You definitely get the best with this! 20/10 would buy again! .. and probably will!

I was recommended by a friend who suggested a tri harness would help with my Bentley's pulling on his lead. I have realised she was right! I love the tri harness, it's exceptionally good quality, I love the colour and the way I was able to have Bentley's name put on it. Several other dog walkers have admired it and so I have been able to recommend your website. I will definitely be using your website again and expect to see other local dogs wearing the harnesses anytime soon.

FAQs

How to put on a dog harness

Start by unbuckling the harness and having your dog sit or stand still next to you. Slip the harness over their head and pull the straps underneath their tummy. Or, if you have a step-in harness, place it on the floor and help your dog place their feet correctly, before pulling it up over their back. Fasten it up securely, making sure it’s not too tight or too loose, and adjust accordingly.

What is the best dog harness?

The best dog harness really depends on the breed, size, and activity level of your dog. The comfortable Hurricane Harness features a useful handle and is super lightweight, while the Premium Harness is a great all-rounder for any dog. The traditional slip-on harnesses offer quick and easy fitting, while step-in harnesses might be better for dogs that dislike harnesses going over their head. And if your dog pulls, the TRI-Harness helps with training to prevent excessive pulling on the lead. You can read more in our Dog Harness Buying Guide. All of our harnesses are lined with Neoprene which is soft and helps avoid harsh burns unlike other brands.

How to measure a harness for a dog

To measure your dog for a harness, grab a measuring tape and wrap it around the widest part of their ribcage, then measure their neck at the base (where the collar sits and not in the middle of the neck). Make sure that the measurements aren’t too tight, but are secure enough that the harness won’t slip off if your dog pulls. 

If you have the harness already, try it on your dog and make sure you can fit two fingers between the harness and their body. Finally, monitor your dog’s behaviour - if they’re showing signs of discomfort or walking awkwardly, it may need adjusting more to suit your dog.

How to use a dog harness correctly

To ensure you’re using your dog harness correctly, you need to make sure it’s properly fitted. This means that it’s tight enough to prevent the harness moving, but loose enough to allow your pooch to move comfortably. Attach your lead to your chosen D-ring, whether that’s on their back or their chest, and get ready for your adventure!
