I thought I would let you guys know that we are up 15 now. We inherited Jessie, a toy American Eskimo, who we think is about 3 years old and is she a spit-fire. She takes on Jazzy, the Great Dane. The other one is an older Cocker Spaniel who we named Butterscotch. The vet says he's probably between 6-10 years old. His teeth are so bad, that it's almost impossible to determine how old he is. The tartar is so thick on what's left of his teeth that they are dark brown (although, they are getting better because of the food we are feeding him). The other part of the teeth are grey and about ready to fall out. He is definitely a growler, but he's getting better...it's just a matter of trust.
