Buddy was the same way only his didn't start until 1yr. I made sure
he was well socialized and was shocked out of the blue at 1yr old
he went for a neighbor's dog. Down hill after that. Every large dog
he saw he wanted a piece of. Over the years and with patience
he has turned himself around. Now he gives, most dogs a chance.
If one barks first tho all is lost. He will go right into attack mode.
Only large dogs set him off.
Today at the vet's he tried to made friends with a very large
Irish setter and Lab. Go figure
