FOUR DOGS wait patiently in line at the front door! Why?! The reason is SURPRISING!
One of the main concerns when thinking of getting a dog and bringing it into your home is certainly cleanliness and hygiene! A dog is obviously not capable of paying close attention to where it is putting its paws, so, naturally it picks up all kinds of dirty things, especially if it is a long-haired dog!
However, even if there is no natural instinct, to be tidy -- dogs can still be trained and consequently, learn how to avoid creating a mess in the house! In fact, in this video, we see a woman who has managed to train her four Golden Retrievers to wait patiently at the front door, so that she can clean their paws before they are allowed to enter the house!
