I don't know how it would work for Neiko's hair but with the Goldens, when they get a mat down there and they do (cuz, yes, they are very hairy down under), I just cut it out rather than trying to wrestle with the mat and have it hurt them for the sake of saving some hair. Nobody looks under there but us, so if it has a small chop out of there it's fine. I recommend shears with a rounded edge, so the skin does not get nicked. I should also mention that they fully trust me with the scissors and don't squirm. And, sometimes I just cut out a part and then work the rest with my fingers. They always look bootiful!
