I have ordered these in XS for my 13 pound Pug/Pekingese mix. I have them in several colors as I love them so much. Have laundered them too as my guy is VERY low to the ground and gets things dirty. Pretty durable but most importantly they are comfortable on him and keep him safe! Beautifully made!Amazon Customer
This is the only harness that has fit my 3lb chihuahua. It is very well made and comfortable on my pup. Definitely worth the money. I wish I'd ponied up for this one from the start, instead of trying a handful of other cheaper ones that were too big or uncomfortable.Amazon Customer
