Many dogs don’t like their feet being touched, let alone their nails being cut. If your dog isn’t used to nail trimming you may need to spend time just getting your dog used to you holding their feet, having your vet or groomer cut their nails. When you start, you may find you can only cut one or two nails at a time. As your dog gets used to the experience you increase the number until you can cut them all in one session.
Before starting, you will need clippers, styptic powder or silver nitrate sticks, and a nail file. Have your dog sit or lie down, whichever is more comfortable for them. If using guillotine style clippers, slide the ring over nail with screws facing towards the dog. Hold the clipper so the moving blade is perpendicular to the nail, and will cut from the bottom to the top. With scissor type clippers hold them so they also cut from the top to the bottom of the nail.
For dogs with light colored nails, cut close to where you see the pink vein. For black nails you should cut only small amounts at a time, looking at the cut edge as you go. When you see the color change from a gray/black to translucent, stop; this is the quick and the nail is as short as you can get it without causing bleeding.
If you do cut the nail too short and it bleeds, use either a silver nitrite stick (cauterises the vessel) or styptic powder (a clotting agent) placed on the end of the nail to stop the bleeding. If you have neither at home can use corn starch, however it will take longer for the bleeding to stop.
After cutting, use the nail file to round and smooth roughened edges.
Some dogs prefer having their nails sanded rather than clipped. You can use a tool specifically made for sanding dog nails, or you can use a grinding attachment on any hand held rotary tool. As with clipping, you may need to start gradually until your dog becomes accustomed to the sound and feel of the grinder.
Nails should be trimmed regularly as long nails can be uncomfortable for your dog and can increase the risk of toe injuries. A good guide is when you hear them tapping as your dog walks. With regular trimming, you should find that nails can be trimmed shorter as the quick recedes.
