I know it's very hard but it does take time.
Try putting on a radio so there is sound in the house.
There are several different products on the market today that
may or maynot help.
I tried them all. The best I can say is he's still a puppy and wants
company. It will take time for him to feel confident being by himself.
Buddy will be 4 soon and he still wimpers when I leave in the morning and
will not touch a treat I leave for him until I arrive home.
He also is in front of the door when I open it. Sometime I wonder if he
sleeps there all day
It's very important to take time, I set aside
1/2 hr every morning and sit and play with him before I get ready for work. I have been doing this since the day I brought him home.Might
sound alittle extreme but they are alone all day so what's 1/2hr?
Try tiring him out before you leave. Give him something to cuddle,
a soft toy perhaps, put the radio on. Make sure he can not get to the
cord. good luck
