Excellent well made product, stopped my dog pulling on his lead. I suggest measuring your dogs as i didnt and just made an assumption on size, so a little big on my boy, but adjusted to the smallest size and fits him well. I cannot recommend this product enough.
It's stoped my dog from pulling on the lead and it's keeping people aware of his needs
I bought the XL harness for my Kelpie x. It was very effective and other dog owners paid attention and kept their dogs away from my reactive girl.
