One thing you hear a lot about with greyhounds that are retired racers is "Separation Anxiety." For those of you who aren't familiar with that, it's basically when a dog gets attached to their owners and then freak out when they are left alone. Typically, owners try to start with just leaving for a few minutes at a time and work up to being gone longer and longer so that the dog knows that the people are always coming back.
Trust me, guys, they always do... And they always wake you up. You should be enjoying your alone time.
I never really had a problem with the people leaving. At first, I would always hope that they would take me with them, but over time I've gotten to the point where I'm not too concerned when my people leave me. In fact, yesterday the people were going out to do some shopping and run some errands. They tucked me in under a blanket because either a) they thought it would be comfy for me and I'd enjoy it or b) they think I'm their little puppet and they can do whatever they want to me.
It was nice to get some alone time. You can tell I wasn't so concerned with them leaving. When they came back, nearly an hour later and walked upstairs, here's all the greeting I cared to muster.
Yeah, I'm very mobile.
