Euthanasia is always a terribly rough decision to make. The cat I let go when I was 13 and the two old dogs I had euth. 5yrs ago (they left 8m apart from each other) still cause tears out of the blue.
How cool that she was able to have all that experience and now start a great career! I once thought I was going to show dogs and started training for it, but the "tutoring" I was getting I felt was leading nowhere so I moved on. I enjoyed 6yrs working as veterinary assistant instead. Loved the type of work (minus assisting with euthanasias), hated the varying and long hours!
Love all the above mentioned breeds, especially Newfies!!! I also have a Cocker. She is a brown and tan and is the friendliest little thing!
