How to Brush a Dog’s Teeth (Successfully)

Just like people, dogs need regular dental care to stay healthy, but they need our help! Brushing is the single most effective way to prevent plaque buildup, gum disease and painful tooth loss and decay, yet many pet parents overlook it.

By learning how to brush your dog’s teeth the right way, you can help protect their smile and overall health. Petco not only offers expert veterinary guidance but also stocks the tools you need in store and online, making dental care easier to start and stick with.

Do I really need to brush my dog's teeth?

Yes! As dedicated pet parents, we make it a point to take excellent care of our dogs. We spend time researching what to feed them with options like fresh, organic and human-grade dog food. We take them to top-notch groomers. We buy them all the toys and treats they could ever want. But when it comes to brushing a dog’s teeth—well, that may be a different story for most people.

According to Petco research, a sizable 61 percent of dog parents say they never brush their dog’s teeth. But routine dental care at home is critical to maintaining your dog’s health. In fact, dental disease affects approximately 80% of dogs (Source: Packaged Facts: "Pet Oral Care Services and Products in the U.S." 3rd Edition, 2018.).

Dog toothbrushes & toothpaste

Start with the right supplies: a soft-bristled toothbrush designed for dogs and pet-safe toothpaste. Never use human toothpaste—they often contain fluoride and xylitol, which are toxic to pets. Plus, the pet-safe ones come in more appealing flavors, such as poultry and peanut butter. For beginners, Petco offers dental starter kits that include both brushes and toothpaste, giving you everything you need in one package. There are also different toothbrush types. The ones with a long handle mirror what we use, while others resemble a thimble with bristles and slide directly over your fingertip. If your dog, well, bristles at one type, try the other. You may want to get one of each so you have options right away, but stick with one for a few days to help your dog get used to it.

Step-by-step teeth brushing

If your canine has never had their canines (or any teeth, of course) brushed, here are five easy-to-follow steps for how to brush your dog’s teeth safely:

1) If your pet is not used to you touching their teeth and gums, start there by gently lifting their lips and quickly looking at their teeth. Reward their patience and good behavior with a treat!

2) If your dog already sits calmly while you examine their mouth and teeth, you can start the introduction of a toothbrush by wrapping a piece of gauze around your finger and gently rubbing it over their teeth and gums. This gets them used to the sensation before you introduce a brush.

3) When ready, hold their muzzle gently and lift their lips to expose the teeth.

4) Position the brush at a 45-degree angle toward the gumline.

5) Use small, circular motions, focusing on the outer surfaces where plaque tends to build up most. Start with just a few teeth at a time—there’s no need to cover the entire mouth in one session.

6) Over time, work up to brushing all areas of your dog's teeth. Aim for about 2 minutes total.

Keep sessions short and upbeat. Praise your dog, offer a dental treat or play afterward so brushing becomes associated with something fun. If you notice persistent bad breath, bleeding, loose teeth, swelling or a painful reaction, contact your veterinarian as these can be signs of dental disease. Petco veterinarians can help diagnose and treat oral health issues before they worsen. They can also recommend products tailored to your dog’s needs.

How to handle reluctance

Not every dog will immediately welcome a toothbrush, and that’s OK. If you’ve ever struggled to brush a dog’s teeth, you’re not alone. Many pets need extra patience and positive reinforcement before they accept regular dental care. Start with finger brushing using gauze or a rubber finger brush. Gradually work toward a full-size dog toothbrush once your pet is comfortable. Those pup-focused toothpaste flavors, available at Petco, can also help.

Short sessions are key. Even brushing for 15 to 20 seconds is progress, and consistency matters more than perfection. End on a positive note with praise or play. You can also reward cooperation with a Petco dental chew or a small healthy dental treat so your dog sees brushing as worthwhile while continuing to aid in good dental hygiene.

Patience and persistence are the secret ingredients. Dogs learn best through repetition and positive reinforcement. Over time most will grow to accept brushing as part of their routine.

Start young and frequently

The earlier you start teeth-brushing, the easier it will likely be since puppies tend to accept new routines more quickly. It’s helpful to get young pups used to having your fingers in their mouth, just like getting them used to you handling their paws helps get them prepared for nail trims down the road.

That said, you CAN teach an old dog new tricks. Older dogs can adapt with gradual training and encouragement. They just need a little more patience. Petco offers puppy-specific dental kits that are gentle for young mouths and helpful for establishing habits early.

Consistency is what matters most. Daily brushing is ideal, but even three times a week can make a big difference. Think of it like your own oral care. Skipping once in a while is fine, but regular brushing is what protects gum and dental health long term.

Why brushing matters

In case you don’t think cleaning your dog’s teeth is a big deal, here’s a brush-up on some medical facts. According to the American Veterinary Medical Association, 80% of dogs show signs of dental disease by 3 years old. Plaque hardens into tartar, which can irritate the gums, cause infection and eventually lead to tooth loss. Worse, oral bacteria can travel through the bloodstream, affecting the heart, liver and kidneys. Brushing won’t eliminate the need for professional dental cleaning from a veterinarian, but it can greatly reduce the severity of dental disease and the frequency in which cleanings are needed.

Brushing helps stop this cycle before it starts by providing regular care and maintenance. With Petco’s wide selection of dental products and expert veterinary teams, you have support every step of the way. Oral care isn’t just about fresh breath but also about keeping your dog happy and healthy.

Supplemental dog dental care

While brushing is best, dental chews, wipes, water additives and special diets can also help reduce plaque and freshen breath. Look for products approved by the Veterinary Oral Health Council (VOHC), which means they meet high standards for effectiveness.

Petco stocks VOHC-approved options both in store and online so you can find the right fit for your dog’s preferences. Whether it’s a chew for after dinner or a dental rinse added to water, these tools can reinforce your brushing routine and provide extra protection.

Ongoing & professional veterinary care

Even with consistent at-home brushing, professional veterinary care is essential. Annual dental exams and cleanings under anesthesia allow veterinarians to remove plaque and tartar from areas you can’t reach, helping to protect your dog’s long-term health.

Visit your local Petco or shop online for dental tools and chews, and schedule a veterinary dental exam today to help keep your dog’s teeth strong for years to come. Our veterinary teams provide comprehensive dental services along with guidance for at-home care.

Combine regular brushing with yearly checkups because good oral care isn’t just fresh breath but also a key way to protect your pup’s overall health. Now that’s something to sink your teeth into!
