Did you know we have 8 designs currently with very small harness sizing of XXS? These are for new puppies or very small toy breeds (Chihuahuas, Pomeranians, Yorkies, teacup breeds, etc) and some kittens and small cats and other animals may fit these small harnesses as well just use the same way of measuring as you would for a dog to get the animal's sizing. Finding products in small sizes like this is a little difficult, as the smaller the items the harder it is to make and
