Nail Clipping (The correct term for nail, as applied to dogs, is claw. Nail is used throughout the text of this website as it is the favored word in the grooming trade)
Dogs that regularly exercise, or play, on abrasive surfaces will generally require less frequent nail clipping than those kept mainly in the house or on soft ground.
Nail trimming is essential for maintaining good health. If a dog's nails are allowed to grow it puts pressure on their toes. It's a bit like us walking in shoes that are too small.
Nails that are too long and left uncut may curl so far under that they pierce the paw pad, leading to infection and debilitating pain.
