My young French Bulldog is marking on all the dog beds and she's trying to be alpha with my other 2 dogs. I need some advice!

I wouldn't allow a dog that is marking in the house and creating issues between the other dogs to have free range of my home. We raise all of our puppies with a lot of management so we can prevent all of these problems from happening in the first place. Many French Bulldogs are tough little dogs and their play style and pushy personalities may not be enjoyed by other dogs. I have found that managing interactions between all of our dogs during the formative months (and maybe longer) is the key to a more harmonious household.

Some dogs simply do not mesh well for play but can be taught there is a time and place for interacting with others. We have 4 dogs and our youngest dog is 17 months old. In the last month, we can finally allow her some off-leash play with our older dogs, until recently she simply didn't respect cues from the others and created a lot of stress in the home. Training and leashed interactions as well as some maturity has allowed us to integrate her into our family group of dogs. Most people don't have the patience to take this time to protect the older dogs and train the youngest addition to the family but we have learned that you have to look at the dynamics of the dogs in front of you and do what's best for the group, even if it's inconvenient for us or not what we had hoped for or expected.

I'd suggest you take a look at our free course on management course at this link https://university.leerburg.com/Catalog/viewCourse/cid/14

I'll link some other resources below.

I'd start with the course Living With Your Puppy first and then the rest in any order you wish.

Happy new year, I wish you the best with your dogs.
