Male dogs do not have heat cycles, only females do. Males can mate at any time of the year.
A dog's nipples may swell during of after her heat cycle. They can stay swollen for up to two weeks after her heat is finished. If they stay swollen longer than that, it's time to have her checked out by a vet.
If the female dog has a normal heat cycle, it last 21 days.
A dog can get pregnant when it is in its 'heat'. A male dog can tell if a female is in season, but this can be any time in the year.
Most females will only allow a male to mount them if they are in heat as this is the time when they are most fertile. Although some females will allow a dog to mate them whilst they are not in heat, there is less chance of the female getting pregnant.
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.

Male dogs don't get in heat, but if they smell a female in heat they can get real frantic in their effort to get to her.
