As happens at so many Yuletide parties, last night the conversation turned to dog urine.
One school of thought held that girl dogs ruined the lawn by making a puddle of evil urine at one place, thus burning a hole in the grass. Boy dogs, on the other hand, tend to spray their pee-pee over a wider area and so cause little or no damage.
I had never heard of such a thing. I thought urine was good for plants and stuff.
I believe it’s like fertilizer. A little is good, a lot will burn the lawn. Though I have two female dogs and no dead spots in my backyard. However, they are smaller dogs (15ish pounds) so they might not have enough output to do any damage.
The Nitrogen in the urine (in the form of Urea) over-fertilizes the grass, causing burns. That said, I’ve never seen it happen to my laws, but I have Bermuda grass, and nothing kills that stuff…
A little, dilute, urine is good for the lawn, though. If you really love your lawn, you can eliminate the dead spots by sprinkling the pee zone with a watering can of plain water immediately after your dog is done.
Or you can train your dog to pee in one spot, which will kill all the grass there, but spare the rest of your lawn.
It doesn’t happen with all dogs’ pee, 'cause just like people, dogs have different hydration levels. If a dog drinks a lot of water and puts out dilute urine, it won’t burn the grass.
If you’ve not had burnt spots on your lawn and then suddenly you do, your dog needs to see a vet to check out his kidneys.
Boy dogs probably cause as much damage as girl dogs - at least mine does. In the yard, he’s peeing to empty his bladder, not just marking like he does on walks, so there’s a puddle when he’s done. Sometimes he doesn’t even bother to lift his leg.
Just for what it’s worth… I have 5 dogs that all pee in my large back yard, 2 boys, 3 girls. I don’t have dead spots, and in fact, my yard guy says he has never seen grass grow as thick & fast as mine does.
Some males damage shrubs. This can be a problem where dogs run loose. It can become a contest of who marked your bush last.
But yes it is the amount and strength and varies, although females are more likely to be a problem. I have had a number of female puppies. Some left brown spots, and some didn’t My neutered male does sometimes.
We had a male dog kill some bushes in our back yard, some kind of evergreen. The urine on the foliage from him peeing on them over a long period of time killed those branches. I guess it didn’t kill the entire bush, but it made it ugly.
Our current female dog doesn’t cause brown spots. Our lawn is low in nitrogen to begin with, and alkaline, and we don’t use quick-release fertilizer, so that may help make it less susceptible. When I was a kid, our female dog did cause brown spots in the lawn. (Surrounded by lush green rings.)
