My mum lives alone and recently has had a spate of attempted break ins. She has wanted a dog for some time and ideally would like an Irish setter like she has had in the past. I don't think however a setter would be much of a deterrent to any potential burglars and am therefore looking for breed suggestions. She prefers larger breeds but her house and garden are fairly small, however the dog would get plenty of walks. It would also more than likely be in the garden with a kennel for shelter for a portion of the day while my mum is out to act as a deterant to burglars. It must be a kind, gentle breed as will have contact with my children. Any suggestions much appreciated.
