I am sorry. I definitely know your pain as it happened to me this week as well. My best friend. I have a new puppy that is quite demanding (and cute) at the moment because I have to train him. He's already bonded to me pretty well in one day. Follows me to different rooms and sleeps by me. :) I keep taking him on the walk I did with my dog Diesel and he is tiny but learning. This is helping some but I still have broken up a couple of times when thinking of, or seeing my dog. I get it. I feel for you. So far having a puppy is helping. Perhaps something to consider in your case as well?
