My family has two large yellow labs that I have been walking, picking up after, washing, and feeding since I was about 12 or 13. The older one is almost eleven and very calm. The younger is seven, but is as high energy as a two year old dog, so I have no problem caring for dogs who are also high energy. Both are friendly to the point that they would not fight back if another dog was trying to attack them. We got them both as puppies so I have experience looking after younger dogs as well. I have also dog sat for a couple of neighbors while they were out of town. I love dogs and enjoy any opportunity I get to meet new dogs and spend time with them. I just graduated high school in June, so my schedule is very open and flexible through most of September.
