I’ve talked to many people who are faithful bulldog owners. They informed me that the absolute best thing you can do for your bulldog is get them a friend. If you can handle the responsibility, you may want to get another dog to keep your bulldog happy. This will give them the constant companionship they crave, give you some free time and also prevent them from causing mischief when you not home. When you bulldog has a friend to turn to during times of boredom, all of their bold behavior will disappear.
From people experience, bulldogs do best with other bulldogs. You should also try to introduce them while they are just puppies. However, if you have an older bulldog that you wish to get a companion for, you should get a younger puppy. A younger puppy is less intimidating for your bulldog and their less likely to become territorial when you bring the little guy home. Two bulldogs can be much better than one and twice the fun.
