I come across that ALOT trainin beagles. You can have 6 well-trained pups runnin at the same time and all it takes it 1 goof-off and they all act like a bunch of fools (well..most of em anyway).
With your 2 dogs..an e-collar is a great idea. That is the simplest and most effective way to break that.

My situation might be similar to yers tho..maybe this'll help too. My dogs are kept in a kennel...and sometimes they stay there fer a few days..esp iffin it's rainin er I got somethin goin on that prevents me from lettin em out. So when a pup gits outta there...he is excited as all git out. So instead of takin em directly to the hunt er the trainin session..I let em "git it out of their system". Once they run around the yard like their tails is on fire fer about 20 minutes...then they go right to werk with little er no problem. My older dogs do that too sometimes..but when it comes to work..they know it and they never skip a beat.
Dogs can learn the diff. between werk and play time..but it does have to be taught. I engrain it it my dogs. Sometimes havin 10 er 12 dogs runnin at a time can be a chore. Esp. when mixin young pups with old dogs. So fore I ever consider addin a pup to run with a large pack like that..I make sure they are trained proper and he/she is ready to hunt.

When I'm ready to put some dogs in the dogbox...they know the difference. They know that when the tailgate drops the bulls** stops. When they ride somewhere they know not to run around like a bunch of fools..and most of the time..the pups grow out of it anyways.

Good luck and let us know how it goes.
