The most dangerous fighting dogs on earth are typically those that have been bred and trained for aggressive behavior, such as the American Pit Bull Terrier, the Staffordshire Bull Terrier, and the American Bulldog. These breeds have a history of being used in dog fighting and have been bred for their strength, tenacity, and aggression. However, it's important to note that a dog's behavior is largely influenced by its upbringing and training, and any breed has the potential to be dangerous if not properly socialized and trained. **

In street fighting, mass can be advantageous as it can provide more power behind strikes and make it harder for an opponent to overpower you. However, size alone is not always the determining factor in a fight. Technique, speed, agility, and experience also play crucial roles in determining the outcome of a street fight. It is important to be well-rounded in various aspects of fighting to effectively defend yourself in a street fight situation. **

In street fighting, strength is generally more important than size. Having strength allows a person to deliver powerful strikes and defend themselves effectively. Size can be an advantage in terms of reach and intimidation, but a smaller, stronger individual can still overcome a larger opponent with proper technique and skill. Ultimately, a combination of strength, technique, and situational awareness is key in street fighting. **

Whether or not to start fighting depends on the situation and the potential consequences.

It's important to know when to walk away and seek alternative solutions. **

Mating in fighting fish, also known as Betta fish, typically begins with the male building a bubble nest at the water's surface using bubbles and saliva. Once the nest is ready, the male will then court the female by flaring his fins and displaying vibrant colors to attract her attention. The female will then approach the male, and if she is receptive, the two will engage in a courtship dance, where the male wraps his body around the female to release her eggs. The male will then fertilize the eggs as they are released, and he will gather them up in his mouth and place them in the bubble nest for protection. **
