Many dogs shed or smell bad. They lack table manners. They may act up around strangers. They have to go to the bathroom constantly, and do not care where they relieve themselves. Depending on what's going on they may continually bark or whine. Heck, even if nothing is going on they may continually bark or whine. It is expensive and time consuming to ensure they have proper medical care, shelter, food, entertainment, and dental care. But if you're an adult you know all this already. It's up to you to train your dog so that its behavior falls into socially acceptable patterns. A dog is a dog. It is not and never will be a furry little human. Expecting that is stupid. But if you're willing to put in work, as obviously these yahoos were not, then in most instances you can have a rewarding and fun relationship with a very social animal who by nature tends to be willing to please. Getting a dog is a big decision and not one which should be lightly taken. Selfish lazy people should never have dogs. Hopefully the dog is not too damaged from the mistreatment it received and can find a new home with people who actually know what to expect from our canine friends. After all, the dog didn't ask to be there. Generally speaking, a dog is just a mirror to what sort of person you really are. And if you are the sort of person who can't handle the "horrible stress" of having a puppy act like a puppy do yourself and your potential puppy a huge favor and get a less stressful and more affectionate and expressive animal like a goldfish. But be careful. You do have to change the goldfish's water from time to time.
