You can never trust any dog 100 percent with a small child.
*any* dog?
I see your dachshund likes to sleep in the bed too. Ours would if she could and lived for 17 years. Alis still misses her, they are a very particular dog. We now have a young pincher, in similar colours, who will get into the bed if she thinks she can get away with it.
You know it makes sense!
