Urine plays NO part in dog mating.
Urine, whether a male or female dog, or human for that matter, will tend to kill grass, yes.
Female dogs give out a scent when they are in heed. Heed is when a female is in a position were that is the only time they can mate. So they have a scent that the Male dogs can smell that scent. Also it is in their Urine.
If you mean, Can dogs be male or female? Then the answer is yes. They can be both.
female dogs are 'bitches', male dogs are just 'dogs'
No, guide dogs can be both male and female.
Could be if she has an infection or disease transmitted through blood(if in heat), urine or that general area. Mainly just an obnoxious awful thing to humans that dogs do especially when not neutered.
A male dog is a Boy and a female dog is a girl. If they breed, then they could have puppies.
they will try to be the alpha a round other male dogs and try to convenes the female that they are more stronger then the other male
yes...and that is gross
Yes.
female look them after and male defend them
