Get your dog used to having their mouth touched, and help them hold their mouth open for a few seconds. 2. Gradually apply the brush to their teeth and brush horizontally. If your dog dislikes this, don't force it; let them get used to the sensation over several days. 3. As they get used to it, start brushing from the canine teeth, molars, and incisors, moving the toothbrush gradually to different areas of the mouth where they are comfortable.
