I have two Yorkies and a Westie. The yorkies act awful when I leave, the Westie just sleeps. Anyhow, my husband has been left with them and they won't eat, sleep or anything until I get back. They pace the floor, run to the doors etc. My little Rowdy is the worst. He is 11 months and very attached to me. Here is what has helped mine with the Sep. anxiety. When you are home, go outside several times a day and don't invite the pups. Tell them to stay and that you will be back. Wait awhile and then go back in. Do this several times letting them know that you will come back. Always tell them to stay and reassure them. When you come back and they are wild and crazy to see you, don't make a big deal, let them calm down. Hope this works for you, anything is worth a try right?
