jfritz,
I agree with Pit Chick, don't feel bad about putting your beagle in a crate during the day. It's for his own safety and like has been said before, if the crate has been properly trained the dog will not look at it as punishment but simply his space or "den". My parents have 2 beagles and many times during the day you will find them sleeping in their crates with the door wide open. Make the crate very cozy with lots of blankets. Beagles like to snuggle and be cozy so the more cushin the better. Also I was taught in puppy class dogs don't know jealously so just because your other dog roams free, your beagle won't know the difference. Good luck. And please keep us posted.
