Nancy, I wonder if Tarzan was grieving for you. Just recently, my daughter boarded her three dogs and went on a five day vacation. On her return she found out from the vet that one of her dogs quit eating or drinking and was even vomiting. He could not find anything medically wrong with him. After she got him home he still was not eating or drinking much. It took over a week for him to get to feeling himself again. I am so sorry that you lost your beloved pet.
