Dog to good home (Bridge City)

Approximately 8-10 month old dog free to good home.
We adopted this puppy when he was about 12 weeks.
It was unknown what type of breed he was.
He has gotten too big and it is hard to care for him due to having small children.
He knocks them over and scratches them trying to play.
He knows a few commands.
Is kennel trained and house trained.
I feel bad he ends up on a lead in our back yard separated from family just because he is too rough for our small kids.
He is a sweet dog who needs someone who would love him give him a yard to run in.
He would also do well with some hunting training he loves water.
Just needs a home without small kids.
