Things to note during the teeth changing period for dogs:

1. Sufficient calcium needs to be supplemented during the teeth changing period, because the demand for calcium is relatively high for growing teeth.

2. During the period of tooth replacement, you need to avoid feeding relatively hard foods, such as molar sticks.

3. You need to pay attention to the oral condition of your puppy. If you find red gums, bad breath, etc., you generally need to take good oral care.

4. Owners should take precautions against items at home to prevent dogs from biting things during the teething period.

5. It is recommended to tie a knot with a wet towel and freeze it, and then bite it on the dog to relieve the pain of tooth replacement.
