Dinah firstname.lastname@example.org, CA 4/6/2010 1:36:48 PM I have been getting my dog's teeth cleaned every month. Canine care has a monthly maintenance program. A friend told me that this would wear away the tooth's enamel. Does anyone know if this is true? I figure that for $20 a month I can keep my dog's teeth from ever getting tartar, but maybe the risks outweigh the benefits?
