I'm really bad. I like to hear where he is or I freak out. I find myself calling for him and then I realise I had no reason to call him to me. I guess it's because he gets out so often but yeah, I do it like 3 times a year. I read a APBT book once that said you don't ever have to clip them if they play and run on concrete/sement a lot because they'll just file them down far enough, and I think that is partially what happens with Niņo.
