I now know more of what I m looking for. Thank you all the answered my ad before. I am looking for a Male English Mastiff/ Boxer cross or similar breed. I am need of a guy that is on the taller heavier side as he will be trained to wear a harness with a bar for me to hold onto so that I may walk instead of always using assitive devieces. Of course no guy will be allowed to have any weight on him until his growth plates are completely healed. This happens most often at about 2 years of age. I do want a mix as I find them at times much easier to work with. I would like a puppy, but would consider a dog that is up to two yers of age if he is house broke, kenal trained and has had at the minimum of basic trianing. I slso want him to have had his shots so that he is ready to take out and to learn what I need for him to do. On the puppy side of things I would like one that is up to date on his shots and has been worked with as far as kids, other dogs, cats and is on his way to potty training. I know that this seems a lot but if you start them out as young a three days you would be surprised as to how they just soak up the information that you give them. Plus they seem to show more of how they wish to learn which is very important for me as I will be continueing his training to become my second in command service dog as my gal still is able to do some things for me.
