Ok, many of you know that Beulah sometimes stays in a kennel in my back yard. I have a privacy fence so no one can see her. The kennel is 10x10 chain link, and it is sitting on a concrete slab. She even has a dog house inside the kennel with a blanket and hay. Here's the problem...She was out there last night, and she hates being out there. Well, she started whining and crying, and howling, so I brought her back in. She jumped on the couch beside me and laid down, and I just happened to look at her feet. Her nails looked horrible. I guess she had been scratching on the concrete trying to dig out, but she had like filed her nails down on the concrete. Is this bad for her? I mean, I know it can't be good, but I don't know what to do. She has to stay in that kennel because if not, she will jump the fence...I mean her nails looked like they hurt, but I could touch them and everything and that didn't bother her....
