BAUMUTT is a company co-founded by a dog named Prince, Eamonn (a professional dog trainer), and Sara (an industrial designer). Eamonn’s experience with Prince’s fearfulness and reactivity toward other dogs led him to become a dog trainer. He noticed that dog owners struggled with getting their dogs to walk beside them without pulling, so they developed a no-pull harness system that doesn’t restrict their natural gait (walk).
BAUMUTT aims to identify training issues and design dog training tools to improve the lives of dogs and their owners.
About the BAUMUTT IN . LINE Non-Pull Dog Harness
The BAUMUTT IN . LINE NON-PULL harness system is developed to help stop dogs from pulling on their leash while not restricting their natural movement. We talked about the problems with gait interference with most no-pull harnesses in the article “Why using a no-pull harness is NOT a magic solution?”.
The IN . LINE harness system features a unique limited slip neck strap section that prevents the harness from rotating and dragging the dog’s leg out to the side when they pull on the leash attached to the front ring.
This innovative design ensures the turning point stays on the front of the dog’s chest and reduces the risk of choking, provided the harness is adjusted correctly. When the leash is pulled, the neck-straps tighten, pulling the back panel forward and causing the chest strap to sit in the armpits, providing stability and effectiveness to the harness. Conversely, when the leash is loose, the neck-straps extend, allowing the back plate and chest straps to sit farther back, avoiding interference with the dog’s leg movement.
The top panel and the piece under the chest are heavily padded to avoid chafing, provide stability to the harness, and distribute any pressure evenly. The back connection point provides more freedom for dogs to explore and is ideal for trail walking, or long-line training. The reflective trim around the edges of the back plate increases visibility in low-light conditions. The harness comes in two colors and five sizes with the webbing width ranging from 20mm (0.8") to 40mm (1.6").
BAUMUTT IN . LINE Non-Pull Dog Harness Review
The IN . LINE Harness was the first no-pull harness Zulu tried, and the leash pressure was a clear and easy way to communicate the concept to her.
Zulu’s awkward proportions placed her between the small and medium harness sizes, so we received both. In the photos, the medium harness is a stone (blue) color, while the small harness is a dusk (burgundy) color. The small harness worked better as a no-pull harness because the neck section fit her narrow neck perfectly, making the sliding section work smoothly. Although the medium harness fit her well as a Y-harness, the neck section was a bit too big, even on the tightest setting, making the no-pull feature less effective.
The adjustable section between the front legs is great to adjust the fit for most dogs between sizes or for deep-chested breeds.
The design of the harness includes a webbing strap between the front legs for adjustable sizing, but this may cause the harness to shift to the side on narrow dogs, particularly when the leash is attached to the back panel. It is suggested to “break in” the back panel by manually turning down the sides after receiving it.
With use, the harness will gradually conform to the dog’s back, improving its stability. However, the sliding issue may still be more noticeable for narrow dogs compared to those with wider backs.
Overall, I was impressed with the high-quality materials used for the harness and its modern, elegant design, which received many compliments from both dog owners and non-dog owners alike.
BAUMUTT LAXO Leah Review
BAUMUTT just came out with their leash called Laxo while we tested their harness, so we wanted to take a moment to talk about that as well.
It is a very neat leash with cool features:
It has flat webbing on the wrist and on the stitch points, but tubular webbing everywhere else for ‘in hand feel’, great look, and tension absorption,
Its colors perfectly match their harnesses,
The Handle Stopper System lets you tighten the handle around your wrist with a slider for extra safety,
Black hardware for an elegant look,
Max Weight: 60Kg/ 130lbs
It is a heavy-duty leash that still feels elegant and light - perfectly matching their harness!
Functionality Review of the BAUMUTT IN . LINE Non-Pull Dog Harness
No-pull correction: This is a harness designed specifically for no-pull training and it is great for that!
Running/Biking: This is not a pulling harness, it doesn’t have padding on the chest straps so not ideal if the dog pulls into it while using the back attachment. It can work if the dog runs next to you without pulling but don’t use it if it rotates fully to the slide because it can interfere with their natural stride and rub against the inside of the front legs.
Hiking: It’s a durable harness that could be great for hikes. The lack of a handle minimizes the chance of the dog getting stuck on something in the woods, while you can still use the back strap to grab the dog when needed.
City walk: Works well, the two attachment points let you switch control points for different situations (walking in a busy area vs sniffing time in a park).
Easy to put on/adjust: It has two buckles on the chest straps, so it needs to go over the dog’s head. Adjusting is easy, and the sliders stay in place well after adjustment. It has 5 adjustment points but the neck strap has limited adjustment due to the limited slip design.
Visibility: It has reflective elements on the back but the harness itself doesn’t come in hi-visibility colors.
The IN . LINE Non-Pull harness and the LAXO leash make a great set for no-pull training. The IN . LINE harness was designed to be used for no-pull training - it’s not a Y-harness where they added a front ring as an afterthought without considering the design of the whole harness.
When using the no-pull ring, the harness stays in place well and keeps the pressure point at the middle of the chest which makes it a lot more effective in turning the dog towards you than most of the no-pull harnesses on the market.
We had some issues with the back panel sliding to the side completely when used off-leash or with a back attachment point but this is a hard challenge to solve for a narrow and skinny dog like Zulu without adding a wider and rigid chest plate between the front legs which would eliminate the ability to adjust the length of that section.
Despite this challenge, the harness is well-made, great-looking, and an ideal solution for anyone in need of a no-pull harness for training or an attachment to prevent their dog from slipping the harness and running away.
