The vet finally sent the bill for Luba's treatment today. It was pretty decent of them to wait 6 weeks before sending it.
I went over and dropped it off in person because I thought it might help me with closure. I'm glad that I went because the vet who looked after her took some time to meet with me and chat about how I am doing. It was very decent of him to do that.
I feel better now. It is time to put my full attention onto Falkor, my surviving dog. His health isn't great - he is going in for tests later in the week. I want to enjoy every day that I have with him.
