Often, a male dog is protective of the pregnant female dog, usually if he is the "mate." Sometimes dogs, mates of the pregnant dog or not, will act aggressivley towards the female dog, also known as the "bitch."
It could be multiple issues. If there is a female, even if she is not in heat, they could get protective over her, or if they feel threatened by this other male dog they will become aggressive.
sexuality is not binary (male/female) it is a wide continuous spectrum from male (psyche) with male parts (anatomy) over male with female parts to female with male parts and female with female parts and even male & female psyches with male and female anatomy!

No, after spawning the male cares for the eggs and fry for the first few days after hatch. The male chases the female away after spawning is finished and she has no further input on the raising process. A male will often kill a female who's not removed from the spawning tank soon after the process is over as he becomes very protective and considers all other fish including the mother as an invader.
no they will not but they will breed and then the male gets very protective over fry(eggs) so provide a hide for the female like a shelter so the male wont eat her. btw u can keep as many females a tank as u wont its the males u want to be worried about. Brian C

Male and female foxes have some key differences in behavior and physical characteristics. Male foxes are typically larger and have broader heads, while female foxes are smaller and more slender. In terms of behavior, male foxes are often more territorial and aggressive, while female foxes are usually more nurturing and protective of their young. Additionally, male foxes may roam over larger areas in search of food and mates, while female foxes tend to stay closer to their den.
