My husband and I adopted a retired racer 6 days ago. He's 3 years old and we just love him. He's such a good dog. My husband was the one who picked him up and brought him home last week and he is VERY attached to him. If my husband goes into a room and closes the door, he begins to whine. Our biggest concern is when we both leave for work. Luckily we are both gone at the same time only 3 days per week. I set up a pet cam and check on him while we're gone. By the afternoon he has calmed down but the mornings are rough. He paces through the house, pants, jumps on the couch, stares through the window and won't play with any of his toys (he will when we're home). We close off most of the house but he has the living room, kitchen and our bedroom to roam around in. He also has a doggy door so he can go in and out as he pleases. We bought a crate just like the one he was in at the rescue and leave it open for him in case he wants to go inside to feel safe. He also has a bed on the floor in our bedroom but seems to spend the afternoons on the couch once he calms down. We leave the radio on and a kong with peanut butter and treats inside. Today I tried closing the curtains so he's not so fixated on staring outside but he just peeks through them. We walk him before we leave for work and again when we get home.
Maybe I'm worrying too much and he will calm down as he gets used to the routine. Any possible advice would be greatly appreciated.
