50 is a lot more than you seem to think. This fight wouldn't even be remotely close.
How would the bobcats hurt the grizzly? Their claws are way too short and their strength way too weak to scratch the bear as well as their teeth. They could not reach a major artery or cut any tendons to cripple.
A jaguar is not that much bigger than a bobcat and relies on stealth and ambush to hunt, a grizzly relies on power and speed to run down and kill what it wants. Now 50 dogs would be different as dogs have powerful jaws and could hamstring and cripple the bear and then go for the kill.
