TM, as Aaron has said, its not having another dog in the house, its the fact that his missus doesn't want another dog period. As my wife once said, "why do you want another one?", its not there "thing" so they don't understand. As for the ultimatums, family comes before dogs even if at times its frustrating, annoying and infuriating...........
P.S. Aaron you told me you cut a old biddy up on the M1 and she chased you for six junctions and battered you with an umbrella, tahts what caused the injuries??? Looks sore mate
