I had the same issue with my retriever after hunting and I would put her up in the Casita
to rest. I would come back and find her stretched out on my bed and propped up on the pillows, even though she had her own comfy bed with a pillow on the floor(I guess the old girl preferred the memory foam). Not a big deal if she was clean, but after retrieving birds out of stock tanks and muddy creeks, I didn't want that on my bed. My answer was cheap and simple. Went to the dollar store and bought the cheapest inflatable raft they had. Paid $1.99 for it and once aired up, laid it across the front of the bed and it created a tall barrier across the bed that she did not want to hurdle. Problem solved cheaply and easily and once deflated,it took up very little space in an upper cabinet and of course weighs very little. Hope this helps.
