I grew up with 2 medium sized dogs that cared for myself mainly because my parents were busy with work and I'm the oldest of 4 children so most responsibility was put on me. They were fed 3 times a day with a water change. We also had a cat that we adopted as a stray but he was an outside cat that was pretty much independent but we still provided him with food and water. I have a dog currently, she is medium sized and spayed. She is not aggressive. I live in a large apartment complex with grassy areas that allows dogs. The complex is crime free with a security guard roaming so your dog is very safe. Any other questions just ask.
