Every night at 8:30 my dog goes in the kitchen and waits there. He waits and waits, and if 20 minutes go by he peeks his head out of the kitchen and stares at me. He does this because everynight at 8:30 he get's his "dessert". He absolutely loves Greenies, and even if I forget to give him anything else that day, he would not allow me to forget to give him his greenies.
I, although for different reasons, also loves these "treats" as not only does my dog eat them MORE than willingly, but it is a simple way to make sure his teeth are always clean and his breath is always fresh. Every visit to the vet and groomers continues to re-assure me that his teeth are in good health, and the only time I have ever heard otherwise was when he was staying with someone else for 2 months who thought it would be a good idea not to give them to him (even though I clearly told them one a day,everyday). He has since gone back on them and his dental health is once again healthy.
