Originally bought a size A but my staffy is just a bit small for it also given that its got a bit of stretch to it. Swapped for a smaller size which was super simple and quick. Its really helping enforce our no pulling training and she seems very happy on walks.

We struggled to find a harness big enough for our Cane Corso Martha. But manage to find one no bother on Bully Billows. Also really like the collector colours . Jodi x
Anti-Pull TRI-Harness® | Training Dog Harness for All Breeds - Purple
The quality of this harness is superb! Although a little stiff, my boy seems comfortable and I'm sure over time it will soften. The colour is beautiful, and it works like a dream. My boy has responded so well to it. I'm attaching my lead to the D ring at the base of his neck, and the difference is night and day. I could not recommend this harness enough! I added the personalisation and had "Do not feed" put on the harness. This is really good quality stitching and stands out clearly. I'll definitely be back for more!!!
Great harness and excellent delivery time, only thing i would change is to have a little bit of material under the back loop as it cant be used this other bullybillows leads as the clasp digs into the back of my dog
Very sturdy and good! It would be even better if the hardware parts were made of metal instead of plastic.
The front ring immediately made a difference and stopped pulling straight away. You can feel and see the quality of the harness
We were absolutely in love with everything, esoecially when it came in the mail and we seen that the color we picked looked even more beautiful in person! However I unfortunately didn’t even get to take My babygirl for even a long distance walk before she had accidentily got ahold of the leash and chewed it in a soot right in half where we cannot walk her with it. I really would love to have a new leash because that kinda is a key factor not only for her to be riding in style and matching but Also for the walks to be as effective because it was truly an amazing leash i could tell when i first put my hand on it it was unlike any other one and I am sad we do not have the leash now
Amazing 🤩
At first we weren’t sure how to get it on, but we learned quickly and easily. It’s very adjustable and our dog looks comfortable and happy in it.
The quality of this harness is excellent, it is clearly well made. The only issue I have is that because my dogs head is small in comparison to her torso, it was a bit tricky to find the right sizing. But this is not a reflection of the harness, which is brilliant! Very sturdy, which I need as my dog is strong!
This is by far the best purchase I have made, we use to use a slip lead and with having a large breed dog and a shoulder injury she just didnt want to listen, well as soon as this harness went on and the front clip was attached it was like she had been perfectly trained to walk to heel. An absolutely massive difference, love having 3 different attachment points as depending on what we are doing I will use a different point. Quality harness by a quality brand, all our dog accessories are bully billows, trust the make and the technology that goes into making the products is outstanding. We have the collar, the harness, name tags and we are already eyeing up our next purchase
Lovely harness! My Doberman, Cooper, tends to pull a lot on the lead — especially when we’re just leaving the house — but I find walking him much easier with this harness. It’s made from high-quality material and seems very comfortable for him. And never mind the colour choice — he looks absolutely adorable in it!
This is much sturdier than the typical harnesses , it’s more comfortable for my bulldog Freya. Shes a strong puller and I can control her much better with this harness. It’s of better quality than others in the same price range, Im confident this one will last much longer than usual two months. I love the shade of purple and it looks more attractive too. Never having used Bully billows before im extremely impressed so is my dog trainer! I won’t be looking elsewhere . I will recommend bully billows to everyone I know. Thankyou for the confidence I now have walking Freya, she’s not perfect but it’s an extreme improvement and less stressful than before.
We really liked the color of breastband. It has high quality. When she tried it on she was confortable with that and it is sturdy, which is important to us because out dog is realky energetic. We are really happy with our order.
Good sturdy harness good for 30kg German shepherd American bulldog cross. Helps to stop pulling on lead
This harness, collar and lead is perfect for Paddy. I have tried several but they just weren’t right until this one from BullyBillows. I also think he looks very handsome!! Thank you
I have four harnesses from various places now and this is the only one that fits my dog without rubbing. It's very strong, extremely well made and worth every penny
Extremely happy with the harness
Brilliant harness. We always struggle to get a harness to sit comfortable on our staffy but this is amazing sits so well on her. Definitely be ordering her harnesses from here now on.
Best company I buy my girl staff
This harness has made a huge difference in being able to manage the pulling when out on walks with our strong big 13 month old pooch. Excellent quality, very well made and love that there are 3 rings on the harness to attach the lead at different points ☺️
Perfect for my furry companion, much better than all those generic harnesses.

This is our second harness. The first one is still fine (had it 2years) but we wanted a new colour for the birthday girl! They are worth the price and fit my bully’s shape well.

Groot is a very strong boy who likes to be ahead! I have used a halti and other harnesses but never really got the result I wanted. I spoke with a trainer friend who also has an EBT and she suggested this harness. It’s absolutely amazing! I can walk Groot comfortably and confidently! Thank you!

After adding our female boxer it was clear that she had never been walked with a harness and was terrible on a collar only so we started with a slip on BB harness. I wanted something to be able to control any pulling so switched them both to the tri harnesses. With the BB harnesses I can walk them with more control. I added the traffic lead for him as he is nervous so allows full control when he feels nervous. Would have got matching for them both but the purple is out of stock!

Great quality and has definitely helped with the pulling. I should have gone a size up but was too impatient and wore it. Now swapping with someone else to get the size C instead.

A good quality harness as per usual from BB. The three attachment points offer a variety of control points which are useful not only to stop pulling, but also for teaching tricks.
