I have an American and an English bulldog, 4 and 3 years old respectively. They were both raised by me from puppies, and have lived in my house since they were 8 weeks old. The larger American (Rose) is typically the "Alpha" of the two, though that's a bit fluid with these. If Shortstack (EB) is even drinking water when Rose approaches, she stops drinking, etc.

Where she's become rude is when Rose is involved in play with me. For example, she will not retrieve, and Rose is all about it. So when Rose is bringing the ball back to me, she bites at her and growls. Often Rose will just drop the ball at my feet and slink away when Shortie is walking all tall at her! The worst scenario is when we are going outside for our daily walk, or even when I let them out just to go to the bathroom. At these times, she'll sometimes bite onto Rose's neck, and just HANG there! Or if Shortie gets out first, she'll "take position" and be ready to bite on when Rose tries to run by her. She's not latching on for all she's worth, but this still worries me. Rose is a big strong dog who can chew up a black Kong. Her drive is really, really high. 10% of her intensity on a spring pole directed toward her sister would be tragic.

But it's the EB I need to manage. She's a weird dog -tough as nails, yet super sensitive to corrections by me. Even a mild "Nahh!" makes her hold her head sideways to the floor. I've tried to go out with both hands free to give her a good scruff correction, but she won't act this way when I'm ready! Likewise, when it happens during fetch, she's never within reach.

I suppose the breeds of the dogs are neither here nor there, but I want everyone to understand the differences in physical prowess/damage potential between the two without posting unwanted pictures. I can't believe my little butterball lights into my sinewy-strong dog who is twice her height! It'd be like me giving an NFL lineman a wedgie. What is most curious to me is that she's doing this to a dog she submits to in almost every other daily interaction.

I think I hear my good buddy... ah yep, here he comes.

Confucious say, dog on leash ALWAYS within reach.

Long-lines on these two anytime they are out of their crates together.

Hahahahahahahahahaha!

I just luuuuuv your good buddy.

Absolutely! Pack leaders have more than one job, but I put protecting pack members from having their necks bitten and hung from by other pack members pretty high on my list.

I've just got to interject here about the tethering. Other than a good diet, the single most important thing I did.

Hi Chip,

Just wanted to chime in that I also have an English Bulldog sharing space with a 2nd dog. No higher than my shins, the EB's a 70lb brick with about a 14" chest width. I know very well the tall walk you're referring to. Mine also does the forceful front foot stamps followed by squaring up and pinching/raising of the rose ears. He's also extremely tough and hardy yet sensitive to even a sideways glance. He knows his place yet I respect the power that can explode out of him.

These two have shared space really well together. The EB (by choice) sleeps & lounges almost all day upstairs and the other is my shadow staying downstairs with me all day. In the evening the EB likes to come downstairs and hang out. It's been a ritual for so long that the other automatically goes to his own crate so the EB isn't bothered by his childish antics. EB gets his potty breaks and playtime outside alone because we've gone through the same scenarios you've described with the exception of latching onto one another. We haven't had that happen. Yet. But I know any time they are together, there's always the potential for something to go wrong. I say solo time apart particularly during play and outside breaks. The crate is our best friend's best friend.

Wanted to add that these two do not play together. Ever. If they want to play, that's what I'm here for.

These two play together constantly. Even tugging on the same toys, etc. without incident. They even share a crate (they had their own, but wound up together when left to their own devices). I feed them side by side, give them high-value treats together, and Rose is never challenged.
This is just approximately one time out of 20 when she's retrieving and (about as often, but heightened in intensity) when going out the front door. I guess I should have explained more back-story, but I didn't want to go long.

As for tethering, that helped when playing fetch with Rose today. I can't tether her, because she's taking off through trees, but I can keep Shortstack by my side -and she's the "problem." I can't get over how long Rose's fuse is!
