Thank you Ginger for your reply. I appreciate all the information I can get on this subject. mary
I can't actually recommend a Rat Terrier breeder or trainer.... apologies. Also because I live in UK I couldn't help with specific details like that anyway.
Rat Terriers do a good job, sure.
But you could keep your options open here, because Jack Russells do very well as rat catchers too. They also kill quite humanely, one shake and the rat is dead. I have seen them in action.
Usually with a rat infestation, you need more than one dog. A small team work better (and very very swiftly!)
