Hmmm, I feel your pain!! Is he allergic to Bison as well? Phelan can chew through just about anything but I have learned some tricks to slow him down....Kongs are only good stuffed, but frozen stuffing at least takes time to get through...If you want to buy those dentabone treats, buy the very largest one and freeze it, i wouldn't recommend allowing him to eat it all in one go though, half and then back in the freezer...froz
en Bison shank bones available at a good pet store, i think ours comes in lamb as well but too small for Phelan
...the big tire, it starts to get destroyed immediately but lasts a couple days until total annihilation occurs...This one use at your own discretion--new toy I found, designed to be used as a fetch toy, not recommended by manufacturer for chewing--best chew toy I've found so far!! It's a solid rubber hammer. It comes in a softer wrench and paintbrush shape but the hammer lasts a couple of months and is well loved
Coconuts are also great, just be careful if your guy swallows stuff as the hair on it is fairly long.
