Sorry, my english is not good, I come from Germany.
On the topic.
So the Kangal is definitely not the strongest. But not even the Prasa or Boerboel. A Boerboel is as strong as a Bullmastiff. He also has not a hard bite, as some people think. I've never seen a fight, who won the Boerboel. No matter what race against. General Molossian as English Mastiff, French Mastiff or Rottweiler dogs are not suitable for Dogfight. The only strong of this breed are Cane Corso and Neapolitan Nopoletano. A Neapolitan is similar to a tibetmastiff. A Cane Corso is about as strong as a CAO or alabai. A Sarplaninacs I find rather weak to the other shepherd dogs.
The only strong Shepherd Dogs are Sivas Kangal and Kaukasin Owtcharka. But I have seen video with a Presa or Dogo Argentino has destroy Kangals in 4 Minuts.. I think these races are about equally: Bully Kutta, Kangal, Kaukasin Owtcharka.
A Cane Corso or Boerboel would have no chance against a Presa.
an American Bulldog is also very strong. An American Bulldog, or a Bullterreir wins 8 out of 10 s fight against a CAO, Kangal and CO.
In the top 5 are clearly Dogo Argentino and the Presa Canario. But a Dogo ist verry stronger than a Presa. I once saw a video where a Dogo has a Neapolitan Mastiff killed in 1 minute. This Dog fight in Argentinien with Pumas! and winn
But the strongest dog is the American Pit Bull terrier. Only the Tosa Inu has a chance against a true game pit. No Cane Corso or Boerboel or Presa or Kangal cann beat a real pitbull. I have a Turkish friend, who told me that the Russians brought Pitbulls in Turkey. The Pit Bull has won all the battles. But pit bulls are the best in Russia, Poland, Hungary, Ireland or USA. The Pitbulls in Turkey or Pakistan are bad, sorry!
Pitbull and Tosa Inu are the strongest, that's a fact! Then there are dogs like Dogo Argentino, Presa, Kangal, Bull Terrier, etc. CAO alabai, Boerboel, Cane Corso, Rottweiler or tibetmastiff are nothing special.
Her watch that video:
