Barking

Please help
We have a 2 year old Rotti Lola and a 2 and s half year old Doberman Bailey, we have always had complaints about them barking but we recently moved house and is now worse than ever, Lola barks if anyone walked past the garden and jumps up at the fence ( trying to save up money to higher the fence)
I live with my 3 children and we are now getting threats from our neighbour.. My 12 year old has been told by him that if they carry on barking he will hit them over the head with a shovel.. He also threatened me with s brick a few weeks ago … The dogs only ever go in the garden for a wee and we take them out most days for hours on walks… We are really upset as we don’t want it to come to the point where the council destroy our fur babies as I’m struggling to save up for the fencing too… Any advice would be very much appreciated xx
