As I have written in the health forum, my 10 year old chi Mimi is losing her sight due to inoperable cataracts. As a result, we're going to start training some new commands to help her in her everyday life. With the help of a book I have got on how to help a sight impaired dog, I'm writing a list of new commands and what they mean. However a couple have got me rather stuck! I have decided that for curbs or single steps (in town for example) I should say 'step up' for going up a curb, and 'down' for going down one. I also need a command to let her know when there will be flights of stairs, and I'm not sure if 'stairs up' and 'stairs down' are different enough phrases from 'step up' for her to learn. I'm also wondering about another command - we have for a long time been using 'wait' to get her to stop at a curb with mixed success! Should I carry on saying 'wait' when she needs to stop moving, or introduce 'stop' as a brand new command? Any advice would be appreciated! She has learned her basics (sit, turn round, stand up) quite well as long as there are treats around.
