This is a cartoon movie, probably from the late 80's early 90's starring a young fox whose family is killed by a man with a "boom stick" he grows up being raised by his 'uncle.'

Would really appreciate any help :)

The Little Fox (81)

A little adventurous fox wanders away from home, and into the woods. He returns and finds his family missing. He's all alone. His experienced and wily uncle takes him under his wing and he learns about the hunter.
