Oscar chews his nails. He recently got groomed and would not let them trim his nails for love nor money. The groomer said she didn't want to distress him further and make him see grooming as a negative experience and I agreed with her. I used to do it myself but once, I cut too far and it bled like mad. I've traumatised him because since then, he's fought like mad when anyone's tried. Oscar gets plenty of pavement walking but they're bothering him and I don't know what to do.
