I usually clip Echo's nails with my fingernail clipper. I've probably done it two or three times since I've had her because she really doesn't care to have it done. She squirms and bites me and really just would prefer I didn't do it.
The other day I got out my clippers to trim my own nails and she immediately put her ears back and proceeded to hide in my bed. I was like.. "aww, it's ok, I'm not trimming your nails today." She doesn't believe a word of it until I actually put the clippers away.
But then I realized she's way smarter than I thought. She recognized the pattern. I get my clippers out, trim my nails, then realize she probably needs it too. Good doggy.. too smart for her own good!
