Nala got a wee cut on her paw last week and is now terrified to go in the back garden. We have decking and stones - she has always peed on the stones until now and basically just sits at the back door trying to get back in whining or trying to jump up at me if I go with her. I've tried putting her on the lead to walk around but she just refuses to walk. I've also tried chicken to tempt her but nothing works. She'll go on the stones in the front garden and at my mums house so it's obviously a mental thing but don't know how to get her passed it. Any ideas?
