I forgot to ask something about Mack. I noticed he is a boxer mastiff mix and I wonder how old he is and how much he weighs. When we got Bower they said he would be a big dog but we thought he was boxer and lab mix and didn't expect him to get too large. Well he is now 7 months and is definately boxer-shepard mix-at three months he weighed 20ish lbs and at six months he weighed 55lbs. It'll be interesting to see if he holds true as a boxer and grows for a couple years instead of just one. I also wanted to note that I think Mack is a gorgeous boy!
