As painful as it was to do, I agree that you did the right thing. You made a very mature and difficult decision and I applaud you. I am sure that Theresa will find a wonderful 4-ever home. Sometimes unexpected things just come our way and force us to make decisions that are so painful, but you are young and have a whole lot on your plate. You sound like a very responsible and caring person too. I too, have a Yorkie who was rehomed to me. She was in a home with a single mom and worked and went to school and although it was very hard for her to do, she knew that giving up Gia to someone old and boring like myself
was the best thing. And Gia had little or no stress with the whole situation. She adjusted quite quickly (as the bossy little Princess) and is a wonderful little girl that I just love with all my heart.
Good Luck to you with school too!
