The Question
“Dear Dr. Paola,
How often should I brush my dog’s teeth? Penny is a medium-sized rescue dog,
breed unknown but likely some Labrador/Pit Bull/Staffy, and she really doesn’t
like us touching her mouth.” – Cass
Quick Info about Penny
Hi Cass,
It’s great that you’re thinking about Penny’s dental care. Veterinary dental specialists recommend brushing your dog’s teeth once a day, as plaque starts to harden into tartar within 24 to 48 hours. Daily brushing helps prevent gingivitis, periodontal disease, and the discomfort and long-term health issues that can come from oral bacteria entering the bloodstream. That said, if Penny resists having her mouth touched, it is important to approach this slowly and gently, always using positive reinforcement to build her comfort and trust.
For dogs who are uncomfortable with oral handling, the process can be similar to teaching tolerance for grooming or nail trims. Begin with brief sessions where you simply touch her chin or lips and pair it with a reward. Over time, work up to lifting her lips and touching the teeth, always keeping the experience positive and pressure-free. In the meantime, you can use supportive tools like veterinary-approved dental wipes, enzymatic water additives, or dental chews to help manage plaque. While these options do not replace the mechanical benefit of brushing, they offer some protection while you gradually help Penny become more comfortable. You might also need to consider a professional cleaning.
Good luck!
