Any of you guys have tips for housebreaking your dog? I don't know if it's because he's a beagle, because he's young (2.5 months), or he just needs more time (I read some stories of 6 month old beagles still being trouble), but he doesn't seem to respond to training like dogs I've had in the past. Usually, with other breeds I can tell when they want to go, but this one (being a hound) always has his nose to the ground!
