Walking is enough for some dogs to wear down the dogs nails as long as they are walking on hard surfaces like concrete.
For the walking to wear down the dog's nails they would need to walk around 1 to 2 hours a day on the hard surface.
If you can ear your dog's nails "click" on the floor when walking they need to be trimmed.
When a dog walks or runs on hard or rough surfaces like concrete, pavement or asphalt it creates friction, which files down a dog's nails naturally.
If you never trim your dog's nails the dog can have difficulty walking, suffer from problems like broken nails, ingrown nails, joint problems and even experience pain.
A dog's overgrown nails can also cause the dog's posture to change and stress the dog's ligaments and joints and lead to possible conditions like arthritis, especially in older dogs.
Long dog nails can also affect the dog's joints and ligaments.
When trimming or cutting your dog's nails you have to be careful to not cut into the "quick" as it can cause bleeding and pain.
The vein in a dog's nail is in the "quick" which is a pinkish-red area that is located in the center of the dog's nail.
The "quick" of a dog's nail contains nerves and blood vessels which can be cut and bleed if you cut the dog's nails too short or are not careful.
For a dog with light colored nails, the "quick" is also easy to see as a pink area, and for dark colored dog nails, the "quick" is more difficult to location, so you have to cut the dog's nails with caution.
The dog's "quick" also extends from the dog's nail bed into the nail itself, and cutting into the "quick" will cause bleeding and pain.
If a dog's nail quick is exposed you should clean the dog's nail "quick" and also wrap it so that you prevent infection.
If the dog's nail "quick" is bleeding you can apply some cornstarch or flour to it to stop bleeding and apply pressure and if it continues bleeding contain the vet or take the dog to the vet.
You can also apply some Neosporin and wrap the dog's foot in some gauze for a few days.
