Most success I have had to date is with a very cheap pair of guillotine clippers from amazon. They are sharp and very quick. I thought they would be really hard, but so far so good.
We still have to use excessive clicking and treats, but I get waaaaaaay more success than I do with force
I've done dremel, normal clippers and these have deffo been the best.
Dremel takes forever, and Fred now associates peanut butter and the noise with NO NO NO. So that's out.
The other clippers just didn't have the force for his big black nails.
The guillotine, I can slot the tip in and snip a sliver off fairly easy.. Although our nail escapades mean I can't use any direct force, or hold his foot to do it yet, and I am only allowed to do a couple at a time!! Although he let me do his front feet the other day! Just the ends, but hey, it's better than nothing! His back feet look like talons.....
I never do bodhi's. ever.
