Why do dogs drink others dogs urine while they are urinating?
Why is the cause and are the effects from this?
Answer by rescue member
Mostly to get information on the sex, age, condition and readiness to mate of the dog the urine is from. I find my males do it with my females pretty exclusively, they are all spayed or neutered, but hopes springs eternal I guess.
No, it won’t hurt a dog, but if he is doing it compulsively, all the time, I would tend to think something is lacking in his diet.
