After research I have to agree with some that Rotties are not bred to attack and I had a kneejerk reaction to that vid....I'll still give them their space.
However, I stand by my opinion that the local judge needs to slap the owner hard with some punishment.
I also believe any dog mistreated can be aggressive and that dog is a tad too aggressive. If you own an animal it should be treated with respect, otherwise you don't deserve that friend.
