Nail trimming is probably the easiest task to do at home. It only takes a couple of minutes every other week and can quickly save you money on vet bills.
Nail trimmers come in a variety of sizes and shapes.
Most are made specifically for the size of dog that you have. Make sure the nail trimmer you choose is appropiate for your dog. I recommend buying a pair of nail trimmers that cuts sideways like a pair of scissors. This style of nail trimmer is easier to use and allows for a quick, clean cuts. I find the traditional guillotine-style trimmers difficult to control especially if your dog likes to move.
