Tie down

When Moped is on tie down he barks, whines, scratches the furniture, tries to get attention from me, pulls on the tie down sometiems getting his collar off and he jumps up on the couch (he's tied down to the couch leg). Once he quieted down, I made him a Kong treat and gave it to him. He was quiet while he had his Kong treat He then started to bark and whine.. When let off tie down, he ran around the house grabbing stuff and playing keep away. He whined when I put him in his kennel until I put the blanket over him.
When Skooter is on tie down he whines to get Moped's treats, but otherwise he is usually quiet on tie down. He started barking because he wanted Moped's treats. He woldn't get in his kennel even though he had a raw bone and treats in the kennel. Eventually I was able to kennel him.
