kinda like a pipe line.
make them spend time with each other.?

You should introduce any new dogs to the others slowly and carefully. However, you can have multiple females living in the same area at the same time as long as they get along. I have two females dogs at home right now, and they get along fine.
Rabies maybe, ask a vet or a trainer.
Yes, they do. I dog-sit for my grandmother's shih tzu or she dog sits my Yorkie from time to time. They get along great!
Pretty much any cats and dogs can get along. It just depends on their personalities. Some cats r dogs are more antisocial or most protective so it might take longer for them to get along. But with time pretty much any type can get along. Usually if they are introduced at a younger age, it is a lot easier to get them to get along.
Depends on the farm and the dogs. I know some dogs that are sometimes used for the driving of cattle, and allowed to freely roam the pastures as outdoor dogs. My "farm dogs", however, are small and mainly spend their time napping indoors and playing in the yard; along with the occasional walk along some dirt road. So, as you must have expected, it depends on where you look.
Dogs are nicknamed "man's best friend". They are smart and can get along with humans well most of the time, unless they are badly treated. Humans have been with dogs for a very, very long time and have become great friends.
Dogs have approximately 320 bones and three types of muscles. To move, a dog uses its striped skeletal muscles. These muscles make movement of the skeleton, skin and certain organs possible.
It depends on the dog, but usually a dog and kitten can learn to get along given careful introductions, time and patience.
cats and dogs, and also their is mice and humans (we count as a animal) and sometimes mice and cat's, also cows and dogs. (the odd time they do get along from personal experience
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.
