Piff the Magic Dragon also had his dog Mr. Piffles cloned before he passed. From what I understand, he tried finding another dog but they never really fit in his act the same way so as Mr. Piffles started to get older, he cloned him and now has Mr. Piffles 2.0.

It's not cheap but I don't think Tom Brady cares about how much it costs.
