Try to start when your pet is young, or after a visit to your vet for an exam/cleaning. There may be painful areas in older (over 2 years) pets, and we do not want to make the experience unpleasant.
Use any type of brush that is comfortable to you and your pet, but make sure the bristles are soft. Human interdental brushes (the little tree types) are great for cats and small dogs.
Remember to use a gentle touch, brushing too hard is often why pets don’t cooperate. Use circular motions and angle the brush about 45 degrees to the gum line. concentrate on the gum-tooth interface.
Be patient, keep the sessions short, make it fun and don’t forget to reward!!!
This video shows how patience and praise can can make brushing rewarding.
I use an electric toothbrush too. Introduce slowly to not frighten your pet.
Great video, stresses the most important points. You can use any brush, even electric, just make sure the bristles are soft and dampen with warm water before applying toothpaste.
