I have a pair of mute swans that one has been acting very aggressive towards the other one. I think its the female. Keeps its wings raised up all of the time lately and chases the other one away. Why? Up until lately and now is the 1st of March they have been staying together now they stay at different sideds of the lake
It depends. Is the male becoming aggressive? If it is then something's wrong. Males are usually protective of the females and pups (depending on breed) so if it is acting aggressive towards the female then it will hurt the puppy's. Other male dogs will be fine around the pregnant female but become aggressive towards the pups. Do your research on the breed to determine what is the best way to protect not only the female and pups but the male because the female will attack the male if he try's to attack the puppy's.
It depends on the species. The female may be aggressive towards the male and the male will stay away or they'll fight, but with Russian dwarf hamsters the father will help.
Male mouse is more aggressive and always press for mating. This makes female mouse offensive towards male.
no they grow aggressive when there is a male in the breeding season
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.
I am not a hamster expert but i would say that a female would be better because males tend to be more aggressive
The male is far more aggressive than the female - they are large, and need to assert their dominance over their territory.
they are probably spawning. check out this sight it helped me: http://www.aquariumfish.net/catalog_pages/goldfish_and_koi/breeding_goldfish.htm
No, there is no difference.
Either the male has built a bubble nest to prepare for breeding, or they are being aggressive towards each other and it's a way of being able to fight.
That's not it's species- but bettas will be aggressive towards other fish. Two males shouldn't be put together, neither should a male and female. Two females would be okay
It depends what you want. In my experience male Corgis are more aggressive but also more loving. Females are less aggressive and less loving. Generally you would have to check out the individual and its history.
