Dogs smell each other to find out 'who' they are dealing with. Each dog has an individual smell. When a dog smells another dog, they find out sex (male/female), constitution (alpha-based or submissive), and health of the other dog. It is also believed that the age of the dog, possible available food resources, and kinship may be part of the results of the sniffing process.
I agree very much with the last answer. When dogs smell each other they are trying to find out the dogs gender, ranking, and were they are from and even if they have a mate or not. So theres your answer!
They are trying to figure out whether they are males or females and whether the females are in heat.
Humans don't sniff buts only dogs do that to get to know each other.
of course
they howl because that's what dogs do to keep in touch with each other when they cant see each other
Yes
Perhaps their sense of smell would alert them, but I do not see too many dogs interested in eating mushrooms.
Through barking and the sense of smell.
because they are like dogs and they smell them there
Dogs recognize each other by smell. That is why they greet each other by sniffing at the mouth or under the tail, where the scent is strongest. This is also why a dog often jumps up in front of you when he meets you; he is trying to smell your mouth.
Usually microchipping, but other than this it's pretty hard. Dogs can identify each other by smell.
They mostly pull sleds, smell each other and roll around in the snow.
It's their way of saying "hello".

Other dogs butts
Two, one in each ear, just like humans do.
They will do that because it is away of saying Hi.
Your dogs aren't gay. Dogs relate my smell and touch and, to an extent, grooming. What you're seeing is healthy pack behavior -- in this case grooming and scent. In your case it sounds like your dogs get along and they are cleaning each other and possibly covering up scent. If dogs are meeting for the first time, they will sniff and occasionally lick each other "private areas". This is how they get to know each other, it's a good sign that they will get along.
