Beagle? It would not matter, what else, try hide and seek in the house. Or tracking stuff. Hide and seek, could be where am I? Once, I hid behind the door of the bathroom and called Rex, my GSD. He came in and looked in the toilet for me, didn't see me and left the room. I again, called him in, and he again, looked in the toilet, so of course, I busted out laughing. And he found me. At other times, he does like to sniff, so we would put treats in a tracking line and have him on leash, and track them. Or you could put 2 to 4 bowls or buckets on the floor, and ask him to find the one treat underneath. I will try to remember more, but our Rex is very nose oriented, and tracking works, look it up with google, you will get more ideas!!!
