It's hard to say for sure. A dog's biting behavior can be influenced by many factors like its past experiences, socialization, and the situation it's in. Usually, a well-trained and socialized dog is less likely to bite without a good reason.
Whether a dog bites or not isn't straightforward. It could be related to how the dog was raised, its breed tendencies, and even how strangers approach it. Generally, most dogs give warning signs before biting, but it's important to be cautious around unfamiliar dogs.
Well, it depends on the dog's mood and training. Some dogs are very friendly and wouldn't bite easily, but others might if they feel threatened or scared.
