The reason why the dog’s nails are bent and stuck into the flesh is because the dog’s nails have not been trimmed for too long, causing the dog’s nails to grow abnormally, become deformed and become stuck into the flesh. The owner should help the dog deal with it in time. If it is not dealt with, it will cause inflammation of the dog's paws. In severe cases, it can also cause metatarsal deformation and joint damage.

Solutions to the dog’s bent nails that are stuck in the flesh:

1. First, cut off the dog’s bent nails. The dog may suffer from pain. If you don't cooperate, you can go to the pet hospital for specialized treatment.

2. After removing the nail that has been pierced into the flesh, clean the wound with physiological saline, then use iodophor, etc. to disinfect it, and finally apply anti-inflammatory drugs and bandage it.

3. Be careful not to let the dog’s paws get wet to avoid wound infection. You can wear an Elizabethan ring on your dog to prevent it from licking and biting the affected area.
