I have had a golden retriever for 15 years and i recently just had to put him down. I have house sat for a family friend that also has a dog and i was required to walk her in the morning, mid day, and the evening for at least 25 min. Also let her out occasionally through out the day in between walks and make sure she had food and water. I am available every day as of right now as i look for a part time job. Also when I was a nanny for a family I was required to make sure their dog was let out at least every hour to 2 hours. I made sure that if we went to the park she came with to get some exercise.
