I have alpha-rolled, with amazing success.

I believe your bull is exercising his alpha.

I have very strong feelings about this issue, all of which I have posted heretofore.

Your baby has lost respect for you as the alpha.

My other posts deal wtih this, and I don't believe a reward system works with an English Bull Dog. They are built and bred for the downfall of cattle.

Their jaws were genetically designed to clamp on the fore leg. The docked and or short tail are designed to keep the cattle from grabbing hold and flinging

I believe we must ALWAYS research our breeds when dealing with behavioural issues.

English Bulls are decidedly single minded.

Neutering was an exceptional step. You must now show him YOU are the boss.

Please see my prior post on that one.

This can be a deal-breaker in so many dogs.

We must grab hold of the causations. What are the triggers?
