Some dogs will develop scabs as their wounds heal, while others will not. This may be related to the dog's breed, age, health, nutritional status, skin condition and the healing aids used. If your dog doesn't develop scabs, it may be because his skin is healthier and heals faster, so no scabs form.
If your dog has a wound or wound, it should be cleaned and treated in time, and Use healing aids under your doctor's guidance. If your dog's skin is unhealthy, he may need to adjust his diet, change his bath detergent, use skin moisturizers or skin beauty products to improve his skin condition.
