Hi we have two senior dogs...both around 50 pounds. One (Charlie) loves EVERYONE! Star is a bit more quiet and what I call "the mama" She wants to make sure everyone is behaving and things are ok. Are you good with staying overnight (we would be leaving Friday morning, returning Sunday night) with these beasts. They are great with walks and love as many as they can get. They are good off-leash in a park and will come when called. No meds needed.
