I started off with a single russell and he did well to find and bolt rabbits but catching them was a different story lol if you really want a terrier id get a ferret to work it with , as said the dog will let you know if there is anything at home then its just net up and enter the ferret , if you do decide to go down this road make sure your terrier knows ferrets are off limits and ALLWAYS make sure your dog doesnt have the opportunity to grab the ferret cause if the ferret bites your dog will kill it no questions asked trust me ive had it happen
Atb whatever you decide
