I've been a part of a foster family for dogs of all ages since 2010 and will continue to do so even longer. The puppy litters I watched over the years have consisted of 4 puppies or less. The oldest "puppies" I've fostered were just about 6 months old but they are usually around 4 to 8 weeks. The oldest dogs I've watched were two small dogs: one was 16 years old and the other was 14 years old. Even before fostering, I watched and walked my neighbor's two dogs during all seasons. If she had not moved away, I would still be walking and caring for them now. I've always had a passion for dogs and my current dog, Ruby, is my second .
