Why Choose OneTigris FIRE WATCHER 2.0?

The FIRE WATCHER is a 1TG classic but it has gone through many upgrades in fit and structure so it wouldn’t look like the pup’s “wearing a t-shirt after losing too much weight”. A lot of our users also asked for metal buckles while some didn’t want the extra weight from heavy duty hardware. We took 99% of the feedback over the years into account, and came up with the FIRE WATCHER 2.0 that now has a heavy duty double metal buckle version.

The FIRE WATCHER 2.0 comes in an upgraded structure with improvements on hardware and stitchwork, thanks to the feedback from our fans and users, and now offers a double metal buckle version for those who prefer the feel and extra strength. Featuring a front chest piece that’s ergonomic and doesn’t hinder movement, rows of looped webbing for you to attach morale patches and MOLLE pouches, and a handy top grab handle with stainless steel D-rings to effectively control your dog. Show K9 power to the max with this awesome piece of kit.

  1. Always measure your dog before making a purchase!
  2. Adjust the straps for dogs with narrow neck/mid sections so they don’t easily slip out of the harness when pulling backwards.
  3. OneTigris harnesses are NOT designed to bear heavy weights and we advise against relying solely on the grab handles to carry your dog.
  4. When loading up pouches for a dog harness or pack, for most dogs, 10% to 12% of their body weight is a good starting point for loading up dog packs. This would be 5-6lb for a 50lb dog, or 2.5-3kg for a 25kg dog. Of course, the right amount depends on a number of factors, such as your dog's breed, physical fitness, and energy level.
  5. Take heed that it is against the law to misrepresent your pet as a service dog and violators are subject to prosecution.
