This nail trimmer features 2 adjustable speeds and a rotating heads that gently trim the nails without giving any discomfort to the pet, the safety guard holds pet’s nail firmly in place to prevent accidental hair winding. Instead of scratches on the floor, you’ll be getting smooth rounded nails in the end.The sound of motor is quiet while on low speed, but on fast speed mode, it can be bit louder. We recommend you to use the low speed at first, to help using it on your dog without scaring him, then when you feel your dog relaxes, you can switch to high speed. Just in case this is your first time trimming your pet’s nails, you need to trim a bit and check the tip of the nail, because if you don’t do this, there’s possibility you could make your pet bleed by nicking the tip of the nail blood vessel. Just for your information, the vein grows longer with an untrimmed nail and naturally recedes with shortened nail. Therefore, never try to cut long nails to short with a single trim, just do a bit every week. Battery not included. Measures 7" long.
