But what is it?
Is it urea, or nitrogen? I have no idea. Are there any gardeners with a
bit of knowledge of chemistry that can answer this one?

Please sir! me! I know this one!

It is nitrogen being applied in the form of urea. Urea breaks down in
the soil very quickly and provides TOO MUCH nitrogen which causes
'scorching' of the grass. When too much becomes diluted to just LOTS
(excuse the scientific jargon) the grass grows back like a
freshly-fertilised lawn (which it is).

I notice you say 'he'. Once he reaches puberty and starts cocking his
leg your problem will disappear. My two bitches will continue to
create havoc for the rest of their lives!

We reduced/eliminated this problem by training the dog to pee/defecate
on command (as RNIB dogs are trained) and keeping a gallon or two of
water in the watering can. As soon as the bitch urinates, water the area
well with at least a gallon of water; this dilutes the urine and your
problem is solved unless/until she develops a fondness for one
particular patch. In that case we used upturned plastic plant pots to
deter her, which worked until she discovered they were great toys...
