Customer photo review of Bullyion Trinity® Dog Harness Anti Pull Military Grade Tactical Training Adjustable

A few teething problems with an exchange but a reassuring courtesy call made a real difference to me. It's rare these days to get a personalised feeling when shopping online but Bullyion went above and beyond for me. The only things I'd suggest is maybe having more adjustment on the neck to go a little smaller and maybe look into the weight of the fastening on the back which can make the harness lean when the dog is off lead. Other than that it still fits well and is secure. I've bought previously from here and will continue to do so. Definitely recommended for quality and durability.

Bullyion Trinity® Dog Harness Anti Pull Military Grade Tactical Training Adjustable

Fantastic harness I would definitely recommend for any dog that needs a tough secure harness. My dog is an in-between fit. Unfortunately to big for his neck, the smaller size would be to small for his chest. It is not this company's fault it is the type of bread we have - Prezzy!!! I can honestly still definitely recommend. 😊

The quality of the collar and harness is superb . So pleased with them . They are for a rescue dog that I am adopting that I get next week , hence why I have not been able to include a photo or video . I would most definitely order from you again . Prompt delivery too . One very happy customer , thank you .

Bullyion Trinity® Dog Harness Anti Pull Military Grade Tactical Training Adjustable

It's a really well made, sturdy harness, and can't fault the quality. My dog is a bull breed cross with doberman and greyhound in the mix, so she has a very deep chest but skinny neck and shoulders, so the harness is only just big enough on her chest and is too loose on her chest/neck. I bought the harness to use the front ring as she pulls like a train, but due to the poor fit it isn't giving me the control I'd hoped for while training her. She also almost got out of it when she reversed. Lesson learned, if the measurements don't fit perfectly, don't buy.

Great fit. Sturdy enough to stop pulling and soft enough so my dog Ollie doesn't feel it on.
