As we have said in a few of our most recent posts, dogs are basically babies with fur! Just look at this Boston terrier. He actually thinks he really is a kid, and that he should in fact sleep in the same bed as his human brother! Why should he settle for anything else! He is your kid too after all.
So, he needs a bed that is as big, and as beautiful, as your human child, and he probably wants a stroller, and a baby bike too! Whether he can use them or not is beside the point. He wants it all! Hilarious.
