My Aunt had two Dobes on the farm when my cousin was born. The dogs slept in one of the tobacco barns (it was heated), but were very gentle with Laurie whenever she was outside. In fact, if she would head toward the front of the house one of the dogs would grab the back of her shirt and kept her from running off. (BTW - in no way were the dogs left to supervise her.)
You wouldn't leave two toddlers unsupervised (one might hit the other over the head with a toy truck), so nor should you leave a dog (any dog) with a toddler unsupervised. Toddlers can learn that your dog's crate is his special bed and when he goes there he needs to be left alone. Let's face it, some toddlers are little terrors and hitting a dog one too many times, especially if the dog has arthritis is going to result in a snap or a bite.
If you are raising a well-socialized dog then you probably don't have a lot to worry about.
