There are few things you can do to help your dog feel better about your departure:
(1) Make sure your dog is well exercised prior to your departure
This will help your dog get rid of physical energy (very important) and have a new, fun, way to bond with you and explore her new area.
(2) Introduce work to eat bowls and toys
Making your dog work for her food is a great way for her to expend mental and physical energy. By giving your dog a work to eat toy before you leave for work, or feeding your dog their dinner in a work to eat bowl, you'll keep your dog occupied for a bit and also help them associate your leaving for work with something awesome – delicious food!
