After our new rescue pup was thiiiiiiis close to wiggling out of his regular harness, we began the search for an “escape proof” harness for him. We tried a few generic ones, but being a chihuahua mix, he’s an odd shape and none of them fit correctly. We decided to make the investment in this awesome harness. It took a bit to find the right fit for him, and had to make adjustments frequently, but now it fits him nicely and he can’t wiggle himself out of it. The quality is top notch, really durable, and the color is nice too. Beyond happy with our purchase!
