Ive posted this before... but Im always on the hunt as well for super durable doggy toys.. as our three destroy just about everything. Rhino bones seem to hold up well in our house. They are more expensive than the run-of-the-mill dog toy.. but they actually last. We also have Kongs.. but as you said, they arent of interest. Racket balls seem to be holding up as well. Eli loves squeaky balls but they get eaten quickly. So we've bought two containers of racket balls.. seems that they get lost quicker than destroyed. Theres the regular blue ones.. and then theres a high-durability one.. thats purple. We havent had any get destroyed yet. =) And they seem to be cheap.. $3 or so for a container of 3.. Sports dept in Walmart is where ours have came from.

We too buy stuffed animals.. or give them the happy meal stuffies.. but Im always vacuuming 5 minutes after Ive given them one.. because it looks like it snowed in our living room. So its not really worth it when your dog is a super-chewer.
