I feel your pain, I too had to put my beautiful, lovable wheaten terrier (Taz) of only 4 years down this past thursday night. He was so wonderful, and well trained to. I just can't comprehend what happened. He too bit my girlfriends son on the cheek and had to be rushed to the hospital. luckily it didn't hit a nerve or muscle, however he will need some plastic surgery in about a year or so. Immediately after the incident we went to the vet to have Taz checked out. She informed us that when a dog bites he will eventually repeat it. This was not good news. She gave us different options, one is to have him trained for aggressive behaviour and two is to put him down. I called the two doctors that do this behavioural therapy and unfortunately one of them was on maternity leave and the second and a huge waiting list. My husband was so concerned about our two kids as well as all of our friends and families kids. Our house is a revolving door of kids. He really didn't want to take a chance. His mind was pretty much made up when the doctor advised him on the second choice. Our kids were very upset by his decision and so was I. I tried so hard to save him. I called everywhere and unfortunately no one wanted to adopt a dog that bites. It's been unbearably painful. Almost feels like loosing my dad all over again. I can't stop crying. My husband and kids had a chance to say good-bye to Taz. I didn't want to be part of it, nor did I want to know when it was scheduled for. I just couldn't say good-bye, and know I feel that I am the only one mourning for Taz. I just adored my dog. The pain is so intense that at times I feel that I am gasping for air. How do you say good-bye?
