I'm curious what breed you do consider the "toughest"?
That question is most often asked by people whom only know thaye want the most bad ass MoFo known to tie on the end of a leash... People for whom goldfish ownership would be much more appropriate.
What does toughest mean to you?
Many breeds have representatives one would consider tough... Patterdale Terriers (Fells, for those in the UK) will routinely go to ground and engage quarry twice their size. They are often very game, meaning they will go against grave injury, exhaustion, overwelming odds... without blinking.
Of couse... Ranging around 9 to 12 pounds, their ability to stop a man is not a strong point, but one look at a good, WORKING Patt will tell you these dogs are tough as rust.
"Tough" dogs in my eye, are the dogs that have historically been given tremendous tasking, and, as either a type, or breed, have remained true to working form.
CO's are very capable animals, gifted with a STRONG aversion to strangers (This is one of the only two breeds NOT to be touched by judges at FCI meets, the other being the Fila. How do you think this translates to a strange vet grabbing a 140 pound adolescent Ovcharka during an examination, or being dropped off for a week at the knl. while the family is away?), Large size, and immense drive given the right, or wrong, set of circumstances.
THe dogs are known for lightning quick defensive responses... There is a saying in Russia: "A Rottweiler will keep you safe from a punk, and an Ovcharka will keep you safe from a punk with a Rottweiler."
THe same could be said for many dogs within their working context.
Nice looking AB,my wife and I are looking to get a dog,we have a 3 year old child,do you consider an AB a good choice?
AB's are a breed very much in trouble. THere are good working examples of the breed out there, but they are few and far between.
Oversized, sloppy, fear-aggresive dogs with no drive and no heart are pretty much the hallmark of the AB presently, along with the GSD, Presa...
Popularity doest these dogs no good at all, and people looking for a pet should buy a pet.
Working dogs need work and need a working env. to thrive and be proven worthy of the work our ancestors did with these animals.
I'm not familiar with what you care to do with this dog at all... But unless it includes serious work, either in protection, sport, hunting, weight pulling... I would much rather advise you to addopt a dog in need from a good adoption group or shelter.
