all dogs chase deer , i'd love to hear all the deer stories , I seen a doe with 2 babies kick the s==t out of a 150lb dog ....... unless there's something wrong with the deer they don't catch them , a deer can clear an 8 foot fence , can go up an almost vertical cliff ....stray dogs eat garbage and die young . if you got a mastiff that can hit 30mph , that is one special dog ............. my dogs are smaller lighter mastiffs , I've run them my entire life , it's what I selected them on , had some amazingly fit agile mastiffs and hounds .......
as far as fighting dogs , your misinformed on that ...... that'd be firsthand info from me .......you seem to have accentuated that ?? all these dogs were selected on fighting ability , what do think is the number #1 predator a farm owner has to worry about is ? it's not deer ............ they're bred for exactly the same purpose American bulldogs are and bordeauxs were , they all were all at one time selected on their ability to fight ......... those folks knew the attributes to be an exceptional fighting dog translated to a lot of working endeavors ........ I've seen fighting dogs as sweet as the day is long , and others that would bite you without question , just for being within range ........the only need I've ever seen for those sharp distrustful defensive aggressive tempers is for folks who just want a dangerous dog as protection , little to no training necessary , there are folks in a position to where that dog works , most dog owners I know are not capable of that responsibility , and that temperament in the majority of dog households is one that will create more bsl laws for me to deal with .......
Mike Sottile knows those dogs got neo in them , you see a farmer in Italy with some unregistered dogs that resemble neos ????? a lost breed ? lots of pics have popped up of that lost breed , how lost could it have been ........ i'm not knocking the breed , they're awesome dogs , a good job has been done in homogenizing the breed , which is where a standard can be helpful ....... better than a standard , you stay within the gene pool , and pick impressive pups that turn into impressive dogs ......... my guess is those farmers didn't have a standard to go by ....... the guy that decided it would be a breed is the guy who had the standard , look at the modern neo and how great that works ............
I've had some fast fit dogs , I don't think the sighthound folks have anything to worry about ...........
and some fast fit dogs to compare them too
