I went to the greenies web site and it says that the greenies LITE are highly soluble and digestible. It also says that dogs need to be supervised while eating them to make sure they are actaully chewing them, and not just gulping them down. Im sure they are fine as long at you do not feed them greenies allll the time and watch them to make sure they are chewing them and not just swallowing them cause i could see how that would pose a problem |
