I'm very sorry about the loss of your husband....
On your yorkie - give him time maybe ? I was away for a week and my girls were the opposite - When I got back - they wouldn't leave my side and practically screamed when I left the house for the week following my return - and they were WITH their dad. He said they stayed by the front door waiting for me for 5 days ...leaving their post only to eat. THAT was depressing for me while I was gone - I felt so guilty.
I bet in a few days things get back to normal - and maybe just kind of stay away from the "man" for a little while ?
