Unbreakable Collar - LARGE (1.5" wide): 17"-22" / Black This collar is durable, well-made and functional. It lasted an entire year withstanding adventurous outings and constant “ruff” housing from my pup. I highly recommend this collar.
Unbreakable Collar - LARGE (1.5" wide): 17"-22" / Purple Love the collar! Wish it had more velcro to put a patch in it but great quality product!
Unbreakable Collar - MEDIUM (1.5" wide): 15"-18" / Tan Camo Great fit. Strong hold exactly what I was looking for
Unbreakable Collar - SMALL (1.2" wide): 13"-16" / Pink Camo Great Quality
Unbreakable Collar - MEDIUM (1.5" wide): 15"-18" / Yellow We have a 65 pound Chow Chow that has pulled other collars and leads stretching the fabric. This collar and lead have been able to withstand his pulling against it with no stretch at all. We’re looking at getting a harness to go with it now, only problem is there is no yellow harness and that’s what we got for his lead and collar
I just made another great purchase! We have a Dogo Argentino who has always had Boss Dog collars and leashes. Currently, she has sets in pink camo, red, and now hot pink. I truly trust Boss Dog, and considering how strong my dog is, I wouldn’t trust any other brand to provide the quality and strength needed to keep her secure. I will continue to advocate for boss dog products as the oldest collar we have is 4 years old and still holds up.
Tactical Collar - XLARGE (2" wide): 20"-28" / Pink Camo The collar is perfect fit for my girl
Tactical Collar - MEDIUM (1.5" wide): 15"-18" / Red White & Blue Feb 26, 2025 at 5:43 PM 5 STARS
Awesome Collar. Lasted about a year with our energetic German Sheppard but this will be our 3rd collar with Boss Dog. First Collar the stitching around the ring ripped causing the ring to fall off. Second one the adjuster ring that loops around the collar broke causing the collar to completely fall apart. Would definitely buy again but would like to see maybe a thicker rod for the adjuster.
Awesome collars! I got my pup a red camo one and he used it forever!!!
