Just for the sake of learning more about breeds, has anyone seen any crosses like this? Pictures would be helpful as well. I think if my boy passes his hip/elbow/eye/thryoid/heart plus att cert plus weight pull title I want to get his sperm collected and preserved with aims to keep his memory alive. I might sound very ignorant so please be easy on me lol I think given the frame of my dog, temperament and weight I think he could be complimented well by combining with mastiff blood. I hit one in a million because he is not really dog agressive yet extremely gentile and patient with our house pets 3 cats and a chiwawa. I know he is not done maturing yet and this can all change but these are just my observations right now. Now please do not get me wrong before all those tests and certifications it is not going to be a few years and again this is only an idea. I don't care about making money or becoming a breeder, I just think it would be neat to hook up with someone that could help out with the other 50% of the blood with the traits to compliment him. I think Bernie is extremely gentile and caring with the family but I see a change in him at night and specially around our yard he becomes extremely protective, he ressembles mastiff dogs with his body and head type. I know I have ways to go and please do not take this so serious for all I know he has horrible hips and it's over. I am just here to state my thoughts and everyone is welcome to join in, maybe this is a terrible idea to begin with and someone can prove me wrong. This is my boy I started cutting the feed a little bit, and we started doing more road work. I ordered a pro weight pull harness that should be here by thanksgiving, I still have half a year to get him xrayed before I decide to try on the heavy weights and hopefully compete.
