If the dog's toenails are too long, it will bring discomfort to the dog, and it can easily hurt people or damage indoor wooden furniture. Sometimes the toenails are too long and can split, causing local infection.
Therefore, you should regularly trim the toenails for the dog with scissors or nail clippings, and then grind them with a small file or sandpaper to smooth them. After trimming, if the dog is abnormal in its movements, the toes should be carefully checked. If there is any injury, you can apply iodine.
Usually, adult dogs should trim their toenails once a month, and breastfeeding puppies should also be trimmed frequently, which can prevent scratching the breasts or other puppies during breastfeeding. The dog's big toe has degenerated, with only four toes on the soles of the feet, but the degenerated big toe will grow into unnecessary and useless wolf claws above the hind limbs, which will hinder walking, and may easily hook plants and trees, and even damage yourself. Therefore, when the young dog is 3 weeks old, you can ask a veterinarian to remove the wolf claws.
