My husband and I are the owners of 5 boxers: 10, 8 and 3 year olds, from our litter, Mom now 8. Three boys (2 fully intact) and 2 girls (1 fully intact). Why intact? Show dogs. After Harley, 3 yr old show dog, started to go off with a handler, he started to become aggressive with the oldest boy, then all of them started to fight. It got so bad I called Joanne Rice. That was early October 2007. It is now early February 2008. After much hard work, I now have a balanced pack of 5 dogs. My husband gave up on them, but as a handler of show dogs and a stubborn mind, we now co-habitate together. They now know who is really the head bitch in charge. Thank you, Joanne. I couldn't have done it without you!!
