He is just lying around the kitchen and I am hearing this crunching sound. The first time I heard it, back in August, I thought he got into something he shouldn't have. On closer inspection, the truth became apparent! He bites his toe nails!! 



My cocker spaniel does this when his need clipped. (ironically, that is what me, my DH and son just did- YES, it takes 3 people to clip a 35 lbs dogs nails, he is such a baby) I would take him to a groomer to handle it, but he is a very emotionally sensitive dog and also 13, doesn't handle trauma very well.
I got him from a shelter years ago and assumed it was due to neglect and anxiety, but who knows...
And he loves every minute of it.My cocker spaniel does this when his need clipped
Our polydactl cat does this, too. At least, she does on 26 of her claws, the 27th grows at at a weird angle and we have to take care of that one for her. DH is joking about wanting to ask the vet to declaw just that one..it tends to get ingrown on her, poor fuzzball.
I would always have to clip it out for her.
One of my cats that has since passed away used to have two toenails that would curl around and become ingrown. It was odd, it looked like it just grew back into where it grew out ofI would always have to clip it out for her.
One of the cats that we have now will chew her nails.

my basenji's have always done this...but then, they're weird.![]()

OT, when I was a child we had a pair of Basenjis, a brother and sister (hence the name boy and girl, nothing else would stick ). Our dogs were absolutely whacko. Do yours climb fences and pick open gates? Ours would repeatedly climb the chain link fence and go around the corner to our old neighbor's house to visit with their Boxer. Same thing with picking open the weird, convoluted gate latch, not your typical horseshoe type, this one was a combination. Nutty dogs. I especially remember the childlike whimper that they made instead of barking.![]()

. They also climbed my sliding board and slid down it (old steel kind, not plastic). They would sleep piled together in a wicker cat bed we had (looked like a cave, pillow inside the wicker hooded basket. I wish my kids coul,d have seen those two. HArd headed,too. THe only dog I have ever had that came close in the stubborn gene is our current demon, Scruffy.
My dog does this every night as part of his before bed grooming.
