that this was a condition caused by bitches. I have been told that
giving the dog tomato ketchup may cure the problem. We try washing away
with water but its difficult to be around every time he piddles. Does
anyone have any experience of this. We love him to bits so if it comes
to it we may have to astroturf..... Thanks

Most products that "fix" this in dogs do so because they contain
sodium, which makes the dog drink more water, so the dog self-dilutes
his own pee.

However, then you're aiding your lawn at the long-term expense of your
dog's kidneys and cardiovascular health.

You could try training the dog to go in one place, & plant something
hardy there, or surround it with shrubs. You could designate the front
lawn as the show lawn, & the back lawn as the "dog pee" lawn, & just
accept that one will never be as nice as the other.

Curiously enough, I just got a lab last December, and that's when I
really noticed the problem. I don't know if labs are more potent, or
just have larger tanks.
