Holding the paw firmly, trip the tip of the nail with a single stroke. Be careful to stop short of the quick, the blood vessel inside the nail. If the dog's nails are very long, trim a small amount. Repeat every 7 - 10 days until nails are at desired length. Monthly trimming should be sufficient thereafter.
Be sure to accustom your dog to having its nails trimmed at an early age to make the experience an enjoyable one and increase the bond between you and you dog. It is important to your dog's well-being to keep the nails properly trimmed.
