I always get my puppy ham bones from tractor supply to chew on while I'm cleaning and doing chores, and he never does anything weird. He just lays down and quietly chews on the bone. Today I got him a beef trachea (I know, ew), and when I gave it to him he held it in his mouth and started whining. He wouldn't settle. He walked around and steady whined. Then he started digging in the comforter and it looked like he was hiding it. He finally took it into his kennel, set it down, and came back out to chew on his other bone. What the heck is his problem? He doesn't growl or get protective over treats or anything, and he would put it right in my hand. I just don't get why he seemed so uneasy.
