I normally use stella and chewy's, Primal and all the common manufactures of raw treats. However, due to being raw treats all of them are freeze dried and they have a soft flaky consistency. Normally this is fine but I recently picked up a Petcube to toss the dog treats to keep him distracted as we've recently moved and he's still adjusting. The petcube works best with hard treats, as it struggles to launch the flaky treats which either fail to launch or just break into crumbs. Does anyone have any recommendations on a hard raw treat that's less an inch or less in size?
