Callie loves soda and water bottels after they are empty altho sometimes she steals a half full one lol but I got a petco giftcard for my birthday and was just walking through the store with my mom and we were about to leave and there it was a two pack of squeaky bottles lol they look like a beer bottle and of course I got them because Callies obsession with bottels and oh my gosh she loves them they are really kinda big next to her but she drags them around by the top and with these they are for dogs so I dont have to watch her the hole time making sure she dosent pull the top off.
