To cut a dog’s nails, start by selecting proper clippers. Hold the dog’s paw firmly but gently, and carefully trim the tip of each nail, avoiding the quick (the pink part with blood vessels). If uncertain, opt for small cuts. Use a flashlight to identify the quick if needed. Reward your dog with treats and praise to associate nail trimming with positivity. Regular trimming prevents discomfort and potential injury. Seek guidance from a veterinarian or groomer if unsure.
