Dogs always provide us with unconditional love. When you have a disagreement with your dog, they forgive and forget within a matter of minutes. And, there is no recollection 5 months later. Dogs never ask us "what's for dinner"? They eat whatever is placed in front of them. Dogs don't care how often we go shopping.
Dogs don't notice that we're not wearing make-up. Dogs don't notice that we've gained a little weight around our middle or accumulated a little cellulite on our butts. Most times, dogs will sit and be quiet when we tell them to. Dogs don't mind if we parade them around the neighborhood on a leash.
Most dogs like being in a cage for a period of time. Dogs are the only creatures whose snoring does not bother us. With your dog, you always know where you stand.
