Lock them in a room, turn the lights off and play enya. The dogs will come out happy as larry, which is to say, happy.
You have to introduce them to each other. IF YOU DON'T KNOW YOU SHOULDN'T BE BREEDING
You put the dog in front of the dog.
If you have a male dog and your bringing another male dog dont introduce them on your yard. Your first male will try to defend his territory and could end up getting in a fight with the other one. Introduce them somewhere else so they are not on either ones territory, if you do this it is less likely they will be aggressive toward each other. If you are bringing a little puppy than your other male dog wont see the puppy as a threat. It worked with my dogs.
yes
Are the dogs in heat? Panting is typically either a sign that the dog is hot, stressed or excited. I am assuming your dog is male since you said "another" male. The other male may be dominant and your dog may be somewhat stressed by the situation which would certainly cause him to pant.
that means the humper is the master
If the biting happens, the male may be aggressive, or the female has a scent of another dog that he doesn't like. It could also be an indication that the male likes the female.
imported, made current, made known, popularized, received
Male dogs can not go into heat.
the polite way is to introduce the female but if the male is more important than he goes first for example you would introduce the president first then his wife If you are introducing a married couple to another person, you'd probably say the husband first. If you are introducing two people, you would first introduce the one you had brought over to meet the other.
Your male dog has to be atleast 2 years of age to be studded out well mated with another dog.
Take him with you wherever you go. Introduce him to lots of different people and dogs. If you're having trouble, get another dog if you can. A play buddy is best.
