I suppose no where s safe........burglars can break in to anything.........we are looking at properties and not many have secluded areas for dogs so at least they cannot be viewed from the road, I even worry about people feeding bones or worse............When it's not hot I do take them with me and I actually rely go out unless some one is here, I go for dog walks then pop in the shopping, in the evening the dogs are in our house with guests who have stayed with use for ages and know us well, so......the risks re fewer e...I even took our tiny pups to a forest, put hem in a cage in the back of the car and unlocked the firest get, drive in and let the others have a run while mum and I stayed around the pups.......not something I will do too often but at least they were with me......
