I now have two boars. Both of them are about 2 and a half months old. Their toenails are like little needles. I want to get them accustomed to me handling their feet so that I can make toenail clipping go smoothly, but I have no idea when it's safe to start actually cutting them.
Can anyone answer to that?
If they have clear nails you will be able to see the quick in the nail. Try to avoid cutting this if you can. It's easier to see if you have some sort of light under the nail. At some point you will accidently cut the quick. No one likes to do this but it will probably happen at some point. Stay calm and don't panic. There will be some bleeding. You can hold a clean cloth or paper towel on the nail until it stops bleeding or use some powder available at animal supply stores just for that purpose. The pig will forget about it very quickly and will not hold a grudge.
If it really scares you to trim them, you can have a vet do it the first few times and you can watch how it's done. But you will have to pay for this service.
I have noticed that if you bathe your pigs, nail clipping is way easier right after a bath. But you shouldn't bathe them as often as they need nail trimming.
One of mine has dark nails, and I just routinely (around every 2-3 weeks) cut off a tiny bit, rather than playing the "Where's the quick?" guessing game. She's pretty calm about it, so I can do it in ten minutes or less, and she knows it means she gets apple (aka piggy anxiety relief, at least for my piggies).
