Suddenly Aggressive Bulldog
We have a 2.5 year old English Bulldog we have had since he was a puppy. All of sudden (for no reason we can figure out) he has become aggressive toward me when I approach him while he is sitting on my wife's lap. He never did this before. Now he snarls & growls & warns me to stay away. Obviously, we want this behavior to stop and we are afraid he might also try to bite.
We have said 'no' and put him in time-out, but it doesn't seem to have helped.
Again, this is out of the blue & we are at a loss of how to proceed.
