If you have a small or medium sized dog with a fine coat, you can absolutely use the Arco for shaving its body. If you have a large dog with a thick coat (looking at you, Doodle owners), the Arco is perfect for clipping sensitive areas such as paws, faces, ears, and sanitary areas, but may not be strong enough to clip its body down. The Arco is also a great solution for shaving cats to keep them tangle and flea free. The Arco kit comes with 2 removable batteries that each of a run time of 80 minutes. With a 75-minute full charge time, keep one battery on the charger and the other in the clipper for non-stop clipping. Your Arco will come equipped with Wahl's signature 5-in-1 blade - a preferred option of professional groomers around the world. Our 5-in-1 blade features 5 different blade sizes - #9, #10, #15, #30, and #40 - in one convenient blade.
