Love the harness! Fits perfectly& the personalisation adds the extra touch
Best non pull harness. The only one that actually works for my bull breed
Absolutely love our recent harnesses from Bully Billows! 🐾 We got personalised ones for our two Staffies and the quality is honestly amazing — you can tell straight away they’re really well made. The clasps are super robust, everything feels secure, and they just look great too. I also picked up a training lead for our younger rescue pup who’s working on her lead manners (aka learning not to pull! 😅). The front D-ring on the harness paired with the training lead has been a game changer — it’s made a real difference already. For our older girl (in the video), we use the back clip which is perfect for our usual walks and makes it really easy to unclip when we’re out and about. Genuinely so impressed with the quality and design — practical, sturdy, and clearly made with real dogs in mind. Would highly recommend! 🐶💛
best product for my staff 🥰❤️
Harness is premium quality which feels safe and secure. Callie seems to be very comfortable in this (just to clarify Callie is my dog 😂) This has 100% improved our walks and my wife is impressed how this has reduced pulling on the lead.
She walks so much better with the harness! No more pull / trying to escape out of it!

This product is wonderful! Next time, I want to order one with a name on it! Everything is so cute 😍
Absolutely incredible harness! Wouldn’t go to another place, this is the only brand I feel confident to walk my 30kg puppy on especially in crowds! Will be a constant customer!
Brilliant, walks great and doesn't pull !
Great service and product. Remy loves her new harness and lead
Amazing! This is our 3rd bully harness and this one is my favourite! Is so sturdy and strong! I Love all the clips for different walks 10/10!
This harness is amazing it's completely changed the way our puppy walks, she used to pull like a train now she can easily be corrected and it makes her pay more attention to us. Even my kids can walk her now!
So I’m on my 3rd harness within a month as Maddie the Baddie got hold of the first 2 and chewed the clasp. These harnesses are brilliant though and worth every penny. Maddie pulls like a train and despite lots of training, doesn’t give a monkeys when she sees another dog she wants to play with, squirrels, foxes, birds, cats or any object she decides she wants to play with. Wearing her harness, means I actually can control her and helping the supposed loose lead walking. I say supposed as it depends on her mood. This harness is a total godsend and I am praying that she doesn’t get hold of it again. Bully billows customer service has been fantastic and I highly recommend this to anyone with a strong, stubborn dog who thinks training is for the weak! Brilliant must have for any cheeky dogs.
My staffie loves her new Bully Burrows Tri harness and will actually come to us to put it on. It seems extremely comfortable for her and that is the most important element. She continues to do the roll in it and any mud or dirt can be sponges off. We also love the front and top D ring to make walks and our little girl happy.
It fits lovely nows shes matching with her son
Love this harness! Super easy to use, good fit and definitely helps her not to pull!
Amazing bit of kit!! She was a puller, instantly the strain and tension was almost gone. We're both so much happier walkies is fun again. Totally recommend to family and friends
Loving the new lead and harness I bought for Ruby makes walking her so much easier. Ruby tends to pull when walking and can be hard to control but with her new items walking has become more enjoyable again
Excellent harness, no pulling what so ever.
Fantastic harness and by far exceeds the quality of any other harness we have purchased. Bully Billows will now be the brand for our girl going forwards! ⭐️⭐️⭐️⭐️⭐️
Great harness, I use with the training lead and Ella does well with not pulling. Looks great and get lots of compliments.
Love the equipment and my dog seems happier in it on walks
amazing
The Bully-Billows Anti Pull Harness is amazing! Not only is it strong it’s also pretty! Maya loves her new harness and as she’s a large dog it makes me happy to know that she is safe and secure in her new harness!
I have 2 dogs as you will see on image however, I bought the harness for my Doberman, Rue. She is a bit of a puller to say the least and when you have over 40kg pulling on one arm, its not good. The harness along with the trainning lead has made so much of a difference and I can now enjoy a walk with them.as Rue does. Just need to get one for my Cocker Spaniel now. The Bully Billows products are so well made as we also have collar and a combat lead aswell as a rope. THANK YOU TO THE BULLY BILLOWS TEAM
We had been through every type of collar, slip leads, no pull harnesses from other companies and these are by far the best!! I wouldn’t say they are completely no pull but they do help to control the pulling! They are quite heavy so wouldn’t have got them when they were smaller puppies but they are perfect now! The quality is really worth the money and I know they will last for years! Really heavy duty for strong dogs and gives us confidence they are safe and secure at all times! Would definitely recommend the collars with the handles too for holding onto if needed, as our boy puppy is a little reactive so is perfect if we need to hold him still quickly!
After only using the harness for a couple of weeks, I have found that my dog is easier to control when she wants to pull. So hopefully another few weeks using the harness should see more progress. Much better than the 2 previous ones bought locally.
Best harness you can get when your dog pulls on walks really good looking too fits perfectly and the material is really good recommended
Brilliant quality harness, beautiful colour.
I have tried a view harness this Bullybillows is the best no pulling , i have full control of my dog , I would only buy from this make , they have trainning videos on hiw to use thete products also. 100%happy
Feel like I’ve got a brand new dog! My puppy pulled like a train I dreaded walking her on the lead to the point where I would do off lead walks as my back couldn’t take the constant dragging and pulling 😅 The tri harness has transformed our walks no more pulling and walks by my side. I didn’t know what to expect as honestly I didn’t think a simple loop at the front of the harness would have such a massive impact but I couldn’t have been more wrong! If you’re in doubt just buy it because it truly works miracles! I recommend BullyBillows to everyone 🫶🏼
When I first ordered the harness from bullybillows the wrong colour was sent. But upon speaking to Emma she quickly sorted the replacement harness and sent it next day delivery. So my girl didn't go without her walks. Thankyou Emma and the team, Bullybillows is the only harness and lead etc that I will ever use.
This harness is lovely!! Such a beautiful colour and has really helped with my staffie X American bulldog Mylas’ pulling. My only suggestion is the size range, my Myla was in between sizes, however the small on the chest was 2inch too small but the medium on the neck was 10inchs too big🙈we opted for the small and while it fits her snuggly, if she grows or puts on any weight we would have to buy another size for her. Overall lovely harness in a stunning colour! Would highly recommend☺️
Perfect fitting quality harness and padded comfort for my bully wouldn’t shop anywhere else I have many products from bullybillows and never been disappointed!
Lovely harness with personalised writing for my blind dog. Fits really well and it's amazing quality.
Easy to put on, my dog looks very comfortable. I like the front D ring, she’s still a pup so bit big but adjusts really easy. Always happy with BB.
So much easier to walk her with it!
This harness is amazing! Our girl is very strong and can be reactive causing her to pull. This harness has made all the difference in her pulling and has made it so much easier to navigate her whilst on her walks. It’s also a bonus that she loves her harness, her tail is wagging from the start of the walk to the end with her new attire! 😍
Best harnesses ever! My Old English bulldog needed a harness that can handle her strength and pulling. We put it on and almost instantly the pulling stopped and she was much easier to navigate. Same goes for my husky, she loves to take detours and will yank your arm off going a different direction, she quite literally has the “squirrel!!” Mentality. But this harness, along with their leashes, helped immediately with navigating her back on our path and prevents her from pulling in a ton of different directions. Great investment ever!
