Had 6 rat terriers. Love the breed. All were house dogs but were great dogs. 1 did like squirrels and 1 was a ball fetching machine.A Fiest, or any of the terrier mixes that mimic the “old farm dog” is one heck of an all around house dog.
They can be had in almost any mix to fit almost any situation and they aim to please.
We have two, one a small lap dog for the wife, and the other is a squirrel hunting machine.
Ours are loosely “Rat Terriers” but that breed has only been recognized for a few years so it’s more a type than actual breed.
Always noticed they look a lot like the "fiests" everyone talks about.
