Dog guilt

I was trying to find a way to clip my poor old dog's hideously long nails tonight. The clipper Shawn bought dented on the first try and cracked Paisley's nail. Great. I tried regular nail clippers and couldn't even fit her nail into them. Then I tried just crazy filing and she looked at me with her sad eyes and I gave up. So, as I sat there, petting her tummy and feeling like the worst pet owner, I found a biggish lump, a little bigger than an egg. My heart just sunk. Who knows what that could be? Nothing good, I'm sure. Poor grandma dog. It could be totally hurting and she wouldn't even complain.
