I totally feel for you. At first, when I walked out the door to go to work, Wall-E would bark at me and it made me sooo sad
. Now, right before I leave I give him his Kong filled with treats and it keeps him pretty happy
I felt sooo guilty leaving my pup alone while I'm working so I bought a pheromone plug-in that simulates the same pheromone that their mothers give off. I can't really notice a HUGE difference in his behavior, but I bought it just in case it would sooth him while he's alone. I also notice that he rarely cries, so again, I don't know if thats because of the pheromone plug-in or not but it might help. I also leave the radio on for company.
It's good to train your pup now in small increments. She'll get used to it in time. Good luck!
