:D I have only ever had 3 boxers, two of which are still with me. The first one I got was when my daughter was 7 weeks old, and funnily enough so was the dog. I can honestly say that from day dot, I had complete trust in my dog with my child. They would go everwhere together, including the pram. I have recently adopted a beautiful girl whom we knew nothing about, she was dumped and has bought joy to our family. I have only had her for 5 months, but I once again have trust in her. She is loyal and loving. with my daughter she is a best friend to her. I reckon as a family dog, boxers are perfect. Yes they can be hyper, crazy, run around like a chook with it's head cut off, but when it comes to kids, my 2 girls are the bestest friends any kid could have. I know people say you should never trust a dog completly, call me mad but I do. It isnt the dog, it is how we humans train them and lead them in life.:p
