Both of our dogs wear Ruffwear harnesses. One of our dogs tends to be a bit more 'adventurous' on walks. Maya still has puppy energy and she loves to be outside. She won't hesitate to dart through wooded areas, jump over puddles, launch herself into leaf piles, etc. Given the adventurous nature of her walks, this brush guard is perfect for keeping Maya's underbelly/chest area protected. We are big fans of Ruffwear products and to this day we remain impressed by the high quality of the harnessess. Purchasing this add-on to the harness (which was awesome to begin with) was a no-brainer. It was a sinch to attach the guard to the harness - took all of 5 mins. It fits perfectly and provides even MORE support and control during walks. Maya doesn't seem to have any complaints and she looks comfortable and happy whenever she wears her harness (see photos). As a matter of fact, I believe she likes the harness even more than she did before we added the brush guard. It seems as though she appreciates the added support and protection. This dog goes absolutely bonkers anytime I show her the harness or suggest a walk. She even dips her head for me to slip the harness on and lifts her paw through the leg loop so I can clip her in. (level of cuteness: 10). Not to mention the added support and weight distribution when utilizing the grab handle at the top of the harness to carry our dogs. The grab handle feature is one of the reasons for buying the harness in the first place. It is super helpful and never seems to cause any discomfort when carrying our doggos from the grab handle. In fact, both our dogs seem to enjoy being carried by the handle on the top of the harness. (our other dog, Cosmo, is an OG at 14 years of age. The grab handle is the BEST for carrying him when his legs get tired or doesn't want to get his paws wet when it rains. He will even walk up to us and position himself at our feet, nudging for us to grab the handle and carry him like a briefcase. He's actually starting to become spolied and doesn't feel the need to walk as he would rather be carried - lol). Now, with the brush guard attached to the harness, the added protection and coverage on the underside allows for even weight distribution when utilizing the grab handle. This proved useful on Day 1 and continues to provide value to this day (this is especially handy for scaling massive piles of icey snow, hiking and running in the woods, and picking them up over large puddles or avoiding excess calcium chloride on the sidewalks - which is obv terrible for any doggo's paws) Overall this is a great product. Ruffwear is one of the VERY few brands that I trust enough to purchase from without hesitation. I recommend their products to anyone whenever the opportunity to presents itself. Our neighbors just purchased 2 Ruffwear harnesses for their dogs after seeing the quality of the product. Ruffwear has yet to disappoint. The harness was already a phenomenal product before the brush guard, so the additional support and protection is the icing on the cake. If you're using a harness that isn't a Ruffwear harness, you're doing your doggos a disservice. I highly recommend this harness and the brush guard addition to ANY dog owner. The added comfort for our doggos, as well as the convenience and peace of mind as their owners makes this an easy call - don't hesitate..buy it.
