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.

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

We used to buy a “strong” harness that cost 4-5 times more than Bullybillows but the stitching came undone and the fabric split. We have had Bullybillows for a few years now and love how well made they are. We love the choice of design and colours. We buy the tri-harness as like the option of the front lead attachment but don’t need to use as much these say as Woody no longer pulls so much. The tri-harness is also great as Woody can be a bit of an escapologist and never had any issues with these. As you can see we walk through woods, fields etc and get covered in mud but no worries as our Bullybillows harnesses wash so easily. We have so many colour - just need an olive green and would love a tartan one!

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

We have bred our dogs and kept pick of the litter and all bar one of the puppies has these harness’s. The turquoise harness pup is the first to get his adult harness otherwise the others are just growing out of the mini range. I couldn’t recommend them enough. Perfectly secure for a strong puller, look great, and better to train our dogs with. Each dog usually has a traffic lead and long lead if we need to pull them closer to us when crossing roads or passing dogs/scared humans it’s quick and easy to grab the traffic one rather then pulling in different longer leads. We regularly travel with the dogs and would also recommend this armed for travelling. We just connect the harness to their seatbelts and they feel safe and we know they are comfortable and we don’t need to gaff changing them from the previous dog harness seats belt to prior to walking. These harness’s come in a great range of colours and sizes for all dogs. Our male has had his for five years and we’ve only just started to notice the colour starting to fade. It’s still a great colour just not as bright as it was. But from the constant machine washing that is expected. Finally from all the washing the harness has not lost its sturdiness etc. The harnesses seem like an expensive purchase but it’s an investment as ours have followed our dogs from puppy to adult hood and we’ve had more then our monies worth.

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!
