I have one adult yorkie and two puppies. My adult yorkie sleeps with us and the 20 week old puppies sleep in their crates. I have seperate crates for them both downstairs in our family room as well as upstairs in our bedroom. I didn't want to keep lugging the crates around.
We plan to keep the puppies in the crates until we're prety confident they are solid with their pee pad training and can hold it longer. Depending on what type of cover you had on their bed, they could misinterpret for an Extra Large pee pad before their fully trained.
I have a white down comforter on my bed and I made the mistake of setting down on the puppies on it a week after we got her and she immediately decided to relieve herself. Totally my fault as i should have known better. LOL.
