Yes, bitches urine will wreck lawns!!! I have two! Apparantely, you can by rocks from pet shops which you leave in their waterbowls (have no idea how they work - sorry) or I have also heard that a tin of tomatoes on top of their food will help. I think its something to do with the acid in their urine.
Sure someone much more knowledgeable will be along in a mo!
We tried the rocks, but both the dogs kept picking them out of the waterbowls and refused to drink with them in, then tried tin of tomatoes in their food, they just looked at me as though I was mad and having a laugh and refused to eat! Tried re-seeded parts of the lawn, you have to make sure you dig out all of the roots, but again we had no luck with that, in the end we dug the bloody lot up, made a patio and a bark play area.
Thought it was only female dogs who caused this, so I got that wrong, sorry. Maybe ask in the gardening section about re-seeding the parts of the lawns that have been damaged, thats just what happened to us, but Im sure someone more knowledgable will be more helpful
oh goodness, i hadn't realised the damage was permanent. it is only a small garden so thankfully should't cost too much. i need to get a cure for the browning forst though before i shell out for re-seeding.
We trained our dog to go in the same place (gravel) - basically every time he started to wee on the grass we gently shoved him towards the gravel. When he went in the right place we gave him a treat. Only took two days to get the idea!
