For instance, I notify her when Bowser the hedgehog is hungry. I stand next to his habitat and whine and whine AND WHINE until Mom feeds him.
I can also let her know when she needs to water the plants (or tell someone else to do it since she can't climb the ladder). I stand at her side and ever so gently stand on one of her surgeried feet until she realizes I am trying to direct her attention to the plants.
The best thing I do is fetch things. I love to fetch books because the paper feels so good in my teeth! Lately mom has been reading many things on her kindle. Carrying her electronic book is not quite as satisfying when she almost hyperventilates until it is in her hands.
Mom had a couple of weeks off of work after surgery and I'm not looking forward to her going back. But maybe since I am such a great service dog I can go with her! My customer service skills are amazing although my typing could use some work...
