I didn't like the dog thing either. This was a disaster waiting to happen. Obviously a bunch of hardworking sugeons do not have the time resources to raise a puppy. One one hand, I am glad they are addressing that issue -- way too many people think you just get a dog and he loves you and that's it, when in fact it's a huge amount of work to housebreak and train a dog. But it looks to me that where they are going with the storyline is that they'll decide they can't handle it and give the dog away and turn that into a moment of comedic relief -- ahh, look, we've got our house back now that we've gotten rid of that devil dog! And that is an absolutely terrible message. I believe that if you adopt a dog you have a responsibility to him forever. I don't think it's a funny thing to have people get a dog becuase he's cute, make no real effort to train him, and then ship him off to the shelter because he's not under control. This is why the shelters are full and perfectly wonderful animals are being killed.
OK I will stop ranting now. Hopefully I'm wrong about where they are going with the dog storyline.
