Animal Care Needed

Looking for two drop ins a day (AM 6-7 and PM 6-7) we might ask for a mid day drop in just depends. If its nice and cooler weather then we would ask to have or dog outside for the day in the morning and then brought back inside for the night. He is older (12) and has been having arthritis issues and he is limping at times, he might need to be given an ibuprofen once a day if it is bad. He is a pit/boxer mix around 85lbs.
