OK.....now the neighbours actually traced the original owners of this dog......after I said I would take photos and ask LOL.
After a few phone calls.....here is what hooch is
His mum is a neopolitan mastiff and his dad a lab X Pitbull.
He is only about 7-8 months old, so has alot of growing to still do.....he is a really nice dog, super smoochy and intelligent.
But my girls still give him a hard time through the fence when they get a chance LOL
