Typical.
PSA: do some research before posting nonsense.
I mentioned I did do research. What I do is attached a canine to the end of a six foot piece of material and take him out to walk around my neighbourhood. He then urinates here and there. Sometimes on my lawn, some time on my neighbours while I talk to him Him being the neioghbour not the dog ) , usually in the ditches along the side of the road (Just so this can be peer reviewed, Yes I do live in the city but we have ditches. Great area.) There are no dead patches on my lawn (well one where I over fertilized), none on my neighbours , none in the other places where my dog relieves himself.) Now my neighbour says that is because he is a male not a female. Of course, he is an accountant and not a scientist. Some would say it is because the urea in his pee is not at a high enough concentration to burn the lawn. I will continue my research.
My point more was the poster I replied to was complaining solely that he thought the dog owner thought his lawn was a bathroom and I took that mean he was grossed out by the dog using his lawn as a bathroom as he did not mention any damage, was that lots of thing go on the lawn so what does it matter what the dog does.
As for weeds that appear where a dog pees and nowhere else. Interesting hypothesis. I would be interested to see the research on that one.
BTW so we don't have to take this much further. If you got a real nice lawn I tend to move my dog away from it. And we are talking number 1 here not number 2 right? Just so this all stays scientific.
ps I do not get the whether the PSA is some name you are calling me or the letters for Prostrate Specific Antigen..
