I think Summer has some very mild separation problems. She's fine at home, where there are other dogs when she's left alone but here she's not. She's good when I leave. I lock her in my room, which is puppy proof with some toys/chews, her kennel open, food and water, and the tv on. I'm only gone a couple hours at a time. Monday, though I changed my schedule and will be gone from 8:40 to nearly 3:00. That's the only time she's alone very long at all and my roomie can let her out about noon anyways, so she's really only alone from 8:40-12:00. When I get home, and open the door, however, she goes nuts. Doesn't matter if I've been gone 5 minutes or 5 hours, the reaction is the same. She cries and barks and yaps from my bedroom until I open the door to let her out. When I let her out, she zooms around the house and jumps all over everything, jumps all over me for about 5 minutes and then she calms down fine. I have been trying to get a treat and make her sit and behave right after I let her out but I don't know if I'm handling this well. Anyone have any advice on how to get her to calm down when I return home? And also how to be calm if she's locked in her crate/room while other people are home?
