My two girls act quite differently with treats. Stevie likes to 'play' with hers. Throwing it up in the air, rolling on top of it, throwing it under furniture etc. She also likes to place it in a certain spot and then 'attack' it
After playing with it, she does eventually settle down to chew it.
Marley just carries hers around the house or to her bed. She just places it in front of her but if she catches me looking at it, she snatches it up in her mouth again.
She only starts to chew her treat when Stevie has finished hers and takes great delight in winding her sister up over the fact that she has still got hers.
