I have dog nail cutters, and I'm trying to trim Buster's nails rather than take him in to have them done at a groomer's or vet. I can't get him to sit still. The only time I've been able to get any of them cut is when he's asleep! I will get one or two cut and then he wakes up, sees me right there and thinks it's time to play. He thinks the clippers are one of his toys. They are the ones that look almost like pliers - not the guillotine style ones. Knock on wood, I haven't cut the quick (he has white nails), and he doesn't seem scared of them at all. He lets me rub his paw pads, play with his feet just fine, but when I have the clippers, it's like they are a chew toy LOL. I don't want to get a stand, but is there a trick to getting them to calm down at least enough to get this done?! He does have dew claws (front only), but they don't seem more sensitive or anything than his regular ones...
Slow and steady is the answer. Get him to calm down, cut one nail, then give him a treat and let him run around and repeat, only do one or 2 nails to start, and build to doing more at a time. Once he is used to getting them all done, work to doing a whole paw before letting him run around, until you can get him to stay still for all his nails, it will take time, but it is well worth it, having to fight with a 50lb dog to cut its nails is not fun.
I also highly recommend getting a Dremel tool and using it rather than clippers.
At first, yes the sound is a factor with the dremel, but they get used to it. If I were you, I would begin now, turning it on for a few seconds, and progress to lightly touching it to one toenail. The key to success with the dremel, in my breed anyway, is early exposure. Good luck.
