Went out long netting this morning and my 2year old deer grey was doing fine on the odd bolter then mates best or favourite ferret how ever you look at it ? pops his head out of hole as my dog is just caught a rab !! Dog drops rab then rags f@&k out of ferret . Now mates mortified , I'm gutted gave mate £10 and will buy him another Jill as I don't keep ferrets is there a way to stop dog killing them in future or just don't take dog again ?????
