Oh for fuck sake.
To everyone threatening to call animal control and reeeeing about the dogs, quick lesson on beagles from someone who used to work with and train dogs.
Beagles are hound category dogs, which makes them natural coursers and trackers. Their sense of smell is one of the best among domestic dogs, their ears are long and floppy to funnel scents better when their heads are down, and their tails stick up straight like a flag so that the hunter on the trail wouldn't lose sight of them. Through and through they're a working breed perfected down to every physical attribute, which means they need to be given either lots of exercise or a 'job' to do.
When Beagles don't get enough exercise, they get bored and find their own 'job' to do. In this case, from what little I've seen about these two guys, what they've ended up doing is taking their 'job' as signalling to the rest of the pack every time something in the environment changes, almost like a guard dog, and Beagles signal by howling. A lot. A car probably went past the house and set them off. Problem with Beagles is that they are notoriously hard to train, like most hounds, as their sense of smell is so acute that it's often a massive distraction. In this case I'd imagine their sense of smell is so overloaded that they'd be signalling at every little visual/audio stimulus in one way or another just to stay sane. In another video Chris responds to their howling by yelling back, which makes them immediately stop; the other pack member acknowledged the signal, job done, no need to howl again until something else happens.
What I can say for certain is that if those dogs were that drastically unhappy, they'd attack and eat each other. I'm not even joking, hounds turn savage very quickly if they're abused, malnourished or depressed as they're not bred to be companion pets and do not necessarily have the same amount of compassion or patience that a different breed would have. The fact that they're still friendly to each other and (assuming) the Chandlers means that these guys haven't completely lost the plot yet, but who knows if they aren't close.
Obviously the situation isn't ideal by any stretch, but all you'd realistically achieve by calling animal control is the seizing of the two pups, and a very swift euthanasia of them both. Either situation is pretty shit, and the bottom line is that neither of these people should own dogs at this time, or at all. Calling animal control would also seriously stress those dogs out even more, and considering the way the Chandlers deal with situations involving authority figures, I can't even imagine how spectacularly badly that would go. Either way, the dogs end up worse for it.
Honestly it's best to let the situation play out, and if anything worry about Sorbet more than those two. When they decide they've had enough and finally go a bit nuts, the cat will be the first to go, followed by the furniture, then finally each other.
