Hi, some advice please!

I have a house on a corner plot with a 7-8ftwide tatty strip of
grass/weeds running up the side which is attractive only to dogs and the
neighbours kids who keep playing football up against the wall!

I'm looking to fill it with something that is spikey/sharp enough to
deter dogs/kids (rather than disembowel them!) and was thinking along
the lines of 'anti-burglar' type plants such as pyracantha, berberis,
and quince.

Is there anything else I should be looking at? The wall is facing SW
and the soil is a heavy clay which does get hard & dry in the summer.
Ideally, suggestions should thrive on negelct if possible, though I'm
not adverse to a bit of work if needed :-)

Thanks...
