actually freezing them may cause more damage to their teeth. my gaia broke a tooth and we had to go to the doggie dentist. the doggie dentist said greenies are one of the top offenders in broken teeth and that ice cubes (even tho they tell us to use them for teething) are some of the worst things to give them. i was shocked too! when i thought about it tho -- it made sense because human dentists tell you not to crunch ice. doggie teeth have a thinner enamel than we do.

the doggie dentist said if you must give greenies pop them in the micro for 5-10 seconds to soften them or feed the lil bits.
