To use dog nail clippers properly, follow these key steps:

1. Familiarize the dog with the clippers by holding the clippers and handling the dog's paws without clipping at first, rewarding with treats to create a positive association.
2. Identify the "quick," which is the sensitive part inside the nail containing nerves and blood vessels. In light-colored nails, the quick is visible as a pink area; for dark nails, cut cautiously in small increments to avoid hitting the quick.
3. Hold the dog's paw gently but firmly. Position the clippers at a 45-degree angle to the nail, following the curve of the nail, and clip just before the quick. For guillotine-style clippers, insert the nail into the stationary hole and squeeze the handle to trim.
4. If the quick is accidentally cut and bleeding occurs, apply styptic powder or pressure to stop the bleeding.
5. After clipping each nail, reward the dog with praise and treats to keep the process positive.
6. Use a nail file or grinder to smooth any rough edges after clipping.

This method ensures safe and comfortable nail trimming for the dog while minimizing the risk of injury or discomfort.
