Urination is how the body disposes of toxins, so yes it can kill grass. Size of the dog does not matter.
Yes, the acid from the cat urine will kill grass.
Yes. Dog urine, regardless of whether is it male of female, will kill grass if it is concentrated enough.
it is not normal for dog urine to kill grass. something is odd - either your dog has something causing unusual urine chemistry or you have very delicate grass! I have 4 dogs and have had others now departed. never did they kill grass. some plants are sensitive to urine but not common grass varieties
Not nearly as bad as dog urine. In other words, no not really.
No, rice will not actually kill live grass. However, rice will deter insects and small rodents from eating your grass.
Urine, whether a male or female dog, or human for that matter, will tend to kill grass, yes.
They make stuff for that
The urine will most likely kill the grass because urine is an acid and consists of toxins your body has removed from your system. I think it leaves brown patches The true reason is because of the high amount of nitrogen found in dog urine it can kill the grass. In a lawn were no fertilizer has been applied, dog urine will increase plant growth and green-up the grass. The problem sometimes comes when your lawn has high nitrogen levels from fertilizer and the dog urinates. This would be an "overdose" of nitrogen and cause the turf to burn. It's a common misconception that "acid" in dog urine kills grass. The truth is that dog urine can have a pH of 6.0-8.0(slightly acidic to slightly alkaline) which is no where near acidic enough to kill grass. True dog urine spots will many times be brown in the middle and growing vigorously around the brown spot. Dog Rocks are great, they reduce the amount of nitrate produced in the urine, which stops it killing off the grass. They are really easy to use, they just sit in your dogs water bowl.
Excess fertilizer [urea is high in nitrogen, low in everything else].
Unfortunately, yes. Both male and female dog urine kills grass. It is the acid in the urine that is the culprit. Since changing their diet does not help, about the only thing you can do is to immediately dilute the urine with water (a bit tedious) or have your dog urinate elsewhere.
Both male and female dogs can cause the grass to yellow. There are commercially available products which will alter the aciditiy of the urine and eliminate the problem. Alternatively one can water the area immediately. I use Dog Rocks, which reduce the amount of nitrate produced, which is what kills off the grass.
Sand is not alive, so urine cannot kill it. However, some creatures like small crustaceans burrow under the sand. It would take a LOT of urine to kill one.
