I'm going crazy finding a toy for Elton that will replace his "Rupert". Tried several non stuffed animals, kongs, rope toys and I'm sure more. Today I thought he liked this ball with a rope (I tried another one before) in the store so I bought it. He will not touch it. I bought him bully sticks and he won't touch them. He WILL chase a ball but only if no other dogs around.

Ideas?
