Quick answer

The best dog toothbrush for dogs under 20 lbs is the Burt’s Bees for Dogs Toothbrush with its ultra-soft bristles and angled head designed for small mouths. If your dog is extra sensitive, the Paws & Pals Dual-Headed Toothbrush offers two brush sizes in one. For a budget-friendly option, the Pet Republique Toothbrush Kit includes a finger brush for gentle cleaning.

What to consider for Dog Toothbrush For Dogs Under 20 Lbs

Small dogs have tiny mouths and delicate gums, so the toothbrush head must be small (under 1 inch) with extra-soft bristles to avoid irritation. A long, angled handle helps reach back teeth, while a non-slip grip gives you control. Look for a brush that is gentle on enamel and safe if your dog chews on it. Also consider whether your dog prefers a traditional brush or a finger brush for easier acceptance.

What to look for in a grooming product (shampoo, brush, clipper or wipe)

When choosing a grooming product for your small dog, match the tool to their coat type. For toothbrushes, ensure the bristles are soft and the head is small. For shampoos, look for dog-safe ingredients with a pH between 6.5 and 7.5 to protect sensitive skin. Clippers should have quiet motors and sharp blades to avoid pulling. Brushes should be gentle on the skin and effective at removing loose fur. Ease of use is key for nervous dogs.

How we chose these picks

  • Evaluated bristle softness and head size for small mouths
  • Checked handle design for ergonomic grip and reach
  • Reviewed material safety (BPA-free, non-toxic)
  • Considered customer feedback on durability and dog acceptance
  • Prioritized products from reputable pet brands
  • Compared price to value for budget-conscious owners
  • Ensured each pick is widely available on Amazon
  • Never ranked a product higher just because it pays a commission

What to avoid

  • Human toothbrushes: bristles are too hard and can damage dog gums
  • Harsh flavors like mint that may deter dogs
  • Brushes with detachable heads that pose a choking hazard
  • Using human toothpaste (contains xylitol, toxic to dogs)

Top 5 Picks

Burt's Bees for Dogs Toothbrush with Ultra Soft Bristles
Best Overall

Burt's Bees for Dogs Toothbrush with Ultra Soft Bristles

View on Amazon

This toothbrush features ultra-soft bristles and a small, angled head perfect for dogs under 20 lbs. The long handle provides good reach for back teeth. It is made from recycled materials and is BPA-free. One limitation is that the bristles may wear out faster than firmer brushes, requiring replacement every few months.

Paws & Pals Dual-Headed Dog Toothbrush
Best for Sensitive Gums

Paws & Pals Dual-Headed Dog Toothbrush

View on Amazon

The dual-headed design includes a small brush for front teeth and a larger one for back teeth, both with extra-soft bristles. The ergonomic handle offers a comfortable grip. However, the dual heads can make the brush slightly bulky for very tiny mouths, and some dogs may find the two heads confusing.

#3
Pet Republique Dog Toothbrush Kit with Finger Brush
Best Budget

Pet Republique Dog Toothbrush Kit with Finger Brush

View on Amazon

This kit includes a traditional toothbrush and a silicone finger brush, giving you two options for cleaning. The bristles are soft and the finger brush is gentle for nervous dogs. The downside is that the finger brush may not clean as thoroughly as a traditional brush, and the kit lacks a travel case.

#4
Vet's Best Dog Toothbrush with Enzymatic Toothpaste
Best Value Set

Vet's Best Dog Toothbrush with Enzymatic Toothpaste

View on Amazon

Comes with a small-headed toothbrush and a tube of enzymatic toothpaste that helps reduce plaque. The brush has soft bristles and a non-slip handle. A trade-off is that the toothpaste flavor (poultry) may not appeal to all dogs, and the brush head is slightly larger than some competitors.

Best for Chewers

Nylabone Advanced Oral Care Dog Toothbrush

View on Amazon

This toothbrush has a durable, chew-resistant handle and extra-soft bristles. The angled head reaches back teeth easily. It is designed for small breeds. One limitation is that the bristles are not replaceable, so the entire brush must be replaced when worn, and it may be too firm for very sensitive gums.

Before You Buy

Key Buying Factors

01

Bristle Softness

Small dogs have delicate gums, so extra-soft bristles are essential to prevent irritation and bleeding. Hard bristles can damage enamel and cause pain.

02

Head Size

The brush head should be small enough to fit comfortably in your dog's mouth, ideally under 1 inch. A smaller head allows better maneuverability around teeth.

03

Handle Design

A long, angled handle helps you reach back molars without straining. A non-slip grip provides better control, especially when your dog moves.

04

Material Safety

Look for BPA-free, non-toxic materials. Some dogs may chew on the brush, so durability and safety are important to avoid choking hazards.

05

Dog Acceptance

Some dogs prefer finger brushes over traditional ones. Consider your dog's temperament and past reactions to oral care to choose a brush they will tolerate.

Living With It

Care, Cost and Maintenance

Brushing Technique

Use gentle circular motions at a 45-degree angle to the gum line. Focus on the outer surfaces of teeth, as inner surfaces are cleaned by the tongue. Aim for 30 seconds per side.

Frequency

Brush your dog's teeth at least 2 to 3 times per week. Daily brushing is ideal for preventing plaque buildup. Start slowly to build your dog's tolerance.

Replacement

Replace the toothbrush every 3 to 4 months or sooner if bristles become frayed. A worn brush is less effective and can harbor bacteria.

Pro tip

To make brushing easier, try using a finger brush first to get your dog accustomed to the sensation, then transition to a traditional toothbrush with a small head and soft bristles.

Frequently asked questions

How often should I brush my small dog's teeth?
Ideally, brush your dog's teeth daily. At a minimum, aim for 2 to 3 times per week to prevent plaque and tartar buildup. Consistency is key for dental health. Start with short sessions and gradually increase as your dog gets used to it.
Can I use a human toothbrush on my dog?
No, human toothbrushes are not recommended. They have harder bristles that can damage your dog's gums and enamel. Additionally, the head size is often too large for small mouths. Always use a toothbrush specifically designed for dogs, with extra-soft bristles and a small head.
What toothpaste is safe for dogs?
Only use toothpaste formulated for dogs. Human toothpaste contains xylitol, which is toxic to dogs, and foaming agents that can cause stomach upset. Dog toothpaste comes in flavors like poultry or peanut butter and is safe to swallow. Look for enzymatic formulas that help break down plaque.
My dog hates having his teeth brushed. What can I do?
Start by letting your dog taste the toothpaste from your finger. Then gently lift his lip and rub the toothpaste on his teeth with your finger. Gradually introduce a finger brush, then a toothbrush. Use positive reinforcement with treats and praise. Keep sessions short and end on a positive note.
How do I choose the right toothbrush size for my small dog?
The brush head should be small enough to fit comfortably in your dog's mouth, ideally less than 1 inch wide. For dogs under 20 lbs, look for brushes labeled for small breeds or toy breeds. The handle should be long and angled for easy reach to back teeth.
Can I use baking soda to brush my dog's teeth?
Baking soda is not recommended. It can be abrasive and damage enamel, and it may cause stomach upset if swallowed. Stick to dog-specific toothpaste that is safe and effective. If you need a temporary alternative, plain water on a soft brush is better than baking soda.
What are signs of dental disease in small dogs?
Common signs include bad breath, yellow or brown tartar on teeth, red or bleeding gums, difficulty eating, pawing at the mouth, and drooling. Small breeds are prone to dental issues due to crowded teeth. Regular brushing and veterinary checkups are essential for prevention.
Is it necessary to brush my dog's back teeth?
Yes, back teeth (molars) are where plaque and tartar accumulate most. They are also harder to clean. Use an angled toothbrush to reach these areas. Neglecting back teeth can lead to periodontal disease, pain, and tooth loss.
Can dental chews replace brushing?
Dental chews can help reduce plaque but are not a substitute for brushing. They work on chewing surfaces but miss the gum line and inner teeth. Brushing is the most effective way to prevent dental disease. Use chews as a supplement, not a replacement.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your pet's diet or care routine, especially if your pet has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
