Start by clicking and treating for any interaction with the bed. After 3-4 clicks and treats for looking/sniffing, wait for more (a paw or 2 on the bed). Making small attainable steps for your dog to make. Let your dog try different things (like my dog nudged the bed with his nose) don’t click just be patient.. it’s okay for your dog to guess.
Note: Toss treat away from bed to reset your dog, UNTIL they finally lay down, THEN place a few treats in between their paws.
Note: If your dog doesn’t have a go to your mat behavior, try laying a towel or another blanket on the elevated bed (some dogs are unsure about the above the ground beds).
