Thanks much for the nice comments, everybody!
I've seen them, haven't tried them. Mine get constipated with raw hide, so I usually avoid anything which looks like that. The duck tenders are made by Vitalife (you can google that) and I bought them at PetsMart. I think PetCo also carries them.
I think of frog dog the same way I think of humans doing a split: youngsters can do it, but as we age our joints just don't have the flexibility. As Marlin is now 10, it amazed me to see him in that pose!
