I too, love to go boating, swimming, hiking in the Adirondacks, frisbee and sniffing! I have lots of friends who I bark with daily. But, the thing I love most is meeting new friends at the Scotia Glenville Dental Center (especially if they take time to massage my ears). You can find me back in the administrative area (I am not allowed to play where the Doctors work), so come say hello!

I tell everyone to brush three times a day and floss, also be sure to come back and see me and the Doctors at Scotia Glenville Dental Center AT LEAST twice a year!! Arf! Arf!
