Animal Care Needed

My animals are a bonded pair and cannot be separated. American bulldog (75 lbs) and domestic shorthair cat (20 lbs). The dog is elderly and so does not require daily walks or much activity. He still has control over his bladder and bowel movements, and only requires a daily pill for his arthritis pain. I'm between houses right now, so I don't know yet the exact duration of needed boarding. They are currently with friends, but it turns out that their oldest son is allergic to the cat, so I am having to find somewhere else for them.
