Glen of Imaal Terriers, like many Terriers, are not always exactly welcoming to other dogs. When this extends over to housemates some owners are shocked, and indeed frightened, by such behaviour. This is an American piece so read quickly through the female dog and male dog terms and have a think about the rest. Would it work for Glens?
