I am excited about a nursing career but am concerned about my pets during long shifts. :imbar I have several cats (which I am not too concerned about) and a poodlex. My poodle gets pretty antsy after I'm gone for say 5 hrs. Putting him outside is not an option. I've been thinking about a pet door or even a pet sitter . The pet door is my best bet but it still makes me nervous. Any advice ?
