all dogs need at LEAST basic obidence training and working breeds do need LOTS more mental and physical stimulation than other breeds.
a cage is a good tool to have to get them through the puppy stage, to help with toilet training and to stop them distroying things when your not arround to watch them ie. at night or when you're out.
luckily we never needed one with our st bernard, shes never been into chewing things.
when she was a pup it was during the summer and we kept her in the garden. she had a bed in the wee outbuilding and the door was always open for her to go in and out. we spend much of our time in the garden in the summer enjoying the weather so there was usually allways someone with her. she just naturally went to pee and poo at the back of the garden far away from the main house and her wee house. i think she only peed on the floor inside our house 2 times maybe, and thats when we first got her and we were keeping her in the kitchen at night. thats also why we made her up a bed in the outbuilding instead. but she never peed in her bed outside because the door was allways open with full accsess to outside. shes never toileted inside our house after that. and now we keep her in the hall at night, or in the living room by the fire in the winter, and she just lays down and sleeps all night till we get up and let her back out in the morning.
shes never distroyed anything, luckily, but i allways keep shoes and the kids toys and stuff out her way just incase.
she is terrible arround food though. i have to put her out the room or outside when theres food in the kitchen. she'd steal everything she could get a hold of when you're not looking. and if i tell her to go away she'll move back then sit staring at me slevering all over the floor. plus i wouldn't trust her with food arround the kids. so i find it safer to just stick her outside or in the other room.
st bernard dont need too much stimulation which is grate for me because i dont have much time running arround after 2 kids. she knows basic obidience: sit, down, say, leave ect. and i take her out with me walking on the lead as much as possible when im going to the park or for a walk round the town with the kids, or to visit relatives or whatever. plus we take her in the car up to the lake or to the mountain to let her off lead for a run arround. people are scared of dogs in macedonia because there are so many street dogs they think of them like vermin. because she is so big people scream when they see her then she ends up barking at them so i dont let her off lead anywhere where there is people arround. its good though out where our wee small holding is, a few miles from our house in the center. we are the last property on the 'illegal' road, off the beaten track!, and if you continue up the lane it goes through a forest and comes out at the lake and theres never anyone arround up there so she can run arround until her hearts content, although she usually just plods allong looking for nasty stuff to roll in
