Make 2013 the year to finally tend to your pet's dental hygiene. Just like your own pearly whites, his teeth need to be brushed too. Not only does poor dental hygiene cause bad breath (what is that, a biscuit from 1982?), but it could also cause more serious problems like oral bacteria and gum disease. In the new year, get him a pet toothbrush and toothpaste (never human products), and make brushing part of his daily routine or at least two to three times a week. And make an appointment for a checkup with the pet dentist while you're at it!
