We have a new puppy & don't know what it is for sure. He came from the animal shelter. He's 13 wks old, 20 lbs & a beautiful brindel color. He's suppose to be boxer & ???. I've done some researched & his nose, muzzle, brindel markings, build, loose skin & size @ 13 weeks are nothing like a Boxer & more like the brindel Mastiff I've seen here. See pictures included. Thanks for your help & any suggestions or thoughts on our Maxie!
