I recently ordered the PerfectFit harness for my Bernese Mountain dog, and I'll admit, I was a bit skeptical at first. I've tried other harnesses in the past, only to be disappointed when they didn't fit quite right. However, after measuring my dog as per the Size Calculator advice and purchasing the recommended size, I was pleasantly surprised – it fits perfectly! Not only does the harness fit like a glove, but it also seems to be well-made and sturdy. Putting it on my dog was a breeze, no fuss or hassle involved. And the best part? I can tell it's built to last. If I ever need another harness in the future, I'll definitely be coming back for another PerfectFit. Highly recommended!
