my fiests are a line that my family started about 5 years ago. we picked out different males and females from different lines and have started to cross them together to get our own line. I'm glad to hear that your fiest is doing well:up:Feist seems to be used as a catch all term for small dogs. Add treeing to feist and it ups the value. There are actual feists that are really good dogs, then there are a bunch of small mutts that people try to brand as treeing feists. As to the schipperke ramill mentioned, definitely not a treeing feist. I've had 2 of them and don't wish to make it a third. They can be good squirrel dogs and tree there share of squirrels. Boy do they have a temper and an attitude. Your rat/feist mix can be called a feist, if it trees squirrels, call it a treeing feist and have fun with it. A good feist can really hunt. I got mine from squirrel hunter on here. I don't know what his stock is out of and really don't care. All I know is her hunting skills are better than mine and she is a ball to take in the woods. Good tempered and good natured, unlike my schipperke.
