Dogs are a little different. One, you have thousands of years of breeding by humans to get desirable traits in their dogs. Two, even the largest of dog breeds tops out around 150 pounds, maybe a little bigger in extreme exceptions. This bear was 7 and 1/2 feet and weighed 700 pounds. Let me write that again - 700 pounds. I don’t see how anyone could be sympathetic to this guy.
700 pounds is a small grizzly. They usually top out around 1,100 pounds. From what I’ve heard from others who know animals, the last thing you want to do with a bear is use pepper spray. A 20,000 volt hot-stick would work better. It leaves them dazed and confused long enough to find your egress.
I have sympathy for him, even though it's a silly occupation. Occasionally an elephant or tiger will go go on a rampage and kill their trainer/owner. These people know the inherent risks they take by getting so close to these animals. Life is a risk: it's even deadly, to us all.
A typical male can weigh 45.4-90.8+ kilograms (100-200+ pounds), a typical female would weigh 45.4-72.6+ kilograms (100-160+ pounds).
Guinness Book of World Records recognizes a mastiff from England named Zorba as the heaviest dog in the world, at over 315lb (142.8 kg).[1] Zorba stood 37 inches (94 cm) at the shoulder and was 8 feet 3 inches (251 cm) from the tip of his nose to the tip of his tail. Zorba set this record in November 1989, when he was 8 years old, and about the size of a small donkey.
