You can first let the golden retriever sit down, lift one foot, hold the toe, so that the toenails leak out, and then trim it with a pet-specific nail clipper. When trimming, be careful not to cut the blood line, otherwise it will bleed. Dogs need to trim their nails regularly. If the nails are too long, they can easily break during exercise and affect the dog's walking. If you can't trim them yourself, you can go to a pet store to find a beautician to trim them.
