ive got an 8 month old plummer bitch, shes coming on well bushing and with rabbits, cought 3 herself, tried to shake them dead but abit big for her, and had abowt 10 more with other dogs. Shes had a dead rat to rag on so knows the scent and also seen a few live ones running and was dying to get at them. Im quite confident she would catch 1 with a half a chance and i dnt think it would take her long to click on to shake. I had her out on sat whilst i was checking the smoker and she just stayed close to me and watched. Ive got abit of ratting to do and i will be taking my pup, 2 experienced ratt
