Heat Cycle: Female dogs go into heat (estrus) about twice a year. This is when they are fertile and receptive to mating. Male Behavior: Male dogs can become more restless, vocal, or even aggressive if they sense a female in heat nearby. Aggression: Sometimes what looks like “anger” is actually competition between males or frustration if they can’t reach the female. Mating Process: When mating does happen, dogs experience a “tie” where they remain connected for several minutes — this is normal biology, not aggression. Care & Safety: Owners should supervise dogs during heat and mating periods to prevent injuries, unwanted litters, or stress.
