I like this collar as my dog likes to get wet every time she sees water ( and it's often ). This collar doesn't get stretched as the other ones she has had before ( leather ones get stretched a lot ). What I don't like is the measurement. I measured as they said and a collar is still a little too big. I was concerned it can be too small , but it's opposite > they need to explain it better. I use it but it's not in the right spot on the neck, I need to buy a smaller one , hoping her neck will get bigger and the one she has now will fit correctly, as i really like it !
