Urine, whether a male or female dog, or human for that matter, will tend to kill grass, yes.
male urine is the worst
nooooooo
Female urine contains male-attracting pheromones...
Some labs do and some labs don't. To be safe, I would assume that they do. It is very easy to distinguish male urine from female urine.
no, but some hormone pills like birth control pills affect the urine pH, and lab can find out if male use female urine
"yes you can tell if the urine is from a female or a male its a very simple process" The Urine Drug Test is usually an immunoassay for drugs, not a test to detect sex.
no
The easiest way is to watch them urinate - if the urine comes from under the belly then they are male if they squat and the urine comes from under their tail then they are female.
Urine plays NO part in dog mating.
Yes. Dog urine, regardless of whether is it male of female, will kill grass if it is concentrated enough.
The average pH of urine is typically slightly acidic and ranges from about 4.6 to 8.0, regardless of gender. Hormonal fluctuations, dietary intake, and hydration levels can influence urine pH, but there is not a significant difference in pH between male and female urine.
