I am very sorry to read about the loss of your husband. I will pray for upcoming days of strength and peace for you.
How is you new baby doing now? I do so hope he is starting to settle in some as you get to know one another. My pup is 6 months old and was having a few off days last week. Nothing I fed him he would eat. Then I remembered reading a post on here about sprinkling parmasean cheese on their food. So that's what I did and added a few drops of warm water. He lapped it up. I did this for 3 meals straight and now he is back to eating his normal food. Just thought I would share that with you. It's worth a try if nothing else has worked yet.
Welcome to YT! I do hope you will stick around. It is a great community so full of great people who have at least thing in common...all things yorkie!
