If your dog's nails are not trimmed for a long time, the nails will become too long and pierce into the flesh, causing tissue infection. At this time, you need to cut off the nails, pull out the nails, disinfect the wound, apply medicine, bandage the wound, and change the dressing every day. Severe cases require oral or injected anti-inflammatory drugs to control secondary infections. Dog nails that are too long may also cause toe bone deformation and joint damage. In order to avoid the occurrence of such diseases, your dog’s nails must be trimmed regularly.
