Ok so Bella is just about 4months old and and her breath is starting to smell. When our boxer was her age his breath did not smell at all. Is this a common thing with yorkies? My other yorkie Lucky has fish breath, I don't know why? I brush his teeth about 5 times a week, I've changed his food, and even tried the greenies. Is there something minty out there that works, or a pill, or something? I love getting kisses from Bella, but I don't like the stinky smell. As for my Lucky, I feel bad cuz I don't even let him lick me anymore. Any suggestions will be greatly appreciated!
