My neighbours at the bottom of the garden have put a hedge about 5 feet
from the end to hide the hawthorn hedge which has now grown into trees
covered in ivy. I have two sets of neighbours at the bottom as their
boundary comes halfway cross the garden end.
The others also chuck their rubbish at the end. By now both sides are
about 4 foot higher than my side.
We have hawthorn hedges (not allowed fences thank goodness) but my point
is that with dogs I need the hedges to be trimmed regularly, just back
to 7 foot high, or else once they've grown into trees it makes it easy
for the dogs to escape into their gardens.

I have been trying for about 2 years to come up with a solution to this
problem which wouldn't look too tidy, even chain link and then grow
hawthorn through it.

Maybe you could also have dogs which could get under or over fences but
not actually get through thick hawthorn? Think of the damage which
'might' be done to their perfect garden then!
I agree with others you were commendably restrained and I would have
immediately planted a hedge behind the fence which, with a bit of luck
would have pushed the fence over in a couple of years!
