Check the condition of the gree dog's hooves. If it is just cracked and not red, swollen or inflamed, it is not a problem. It should be caused by dry skin. The owner can use Vaseline and moisturizing lotion to apply to the dog 3-4 times a day. It will get better in a few days; if the Greyhound's hooves are dry, cracked, red and swollen, the owner should first use disinfectants to clean the meat pads, and then apply anti-inflammatory drugs.
