both owner was a little bewildered why their kids were losing their control, these are two bull dogs with addiction to fighting, and alway forgeting everything once fighting eachother.

suddenly a old but strong man came up to one dog and lift up his rear legs, who seemingly lost his supporting and stopped their biting immediately.
