Also, they need to lose weight, do not free feed. Serve them measured amounts twice a day, if they don’t eat within 10 minutes, pickup, store in fridg and offer at the next meal time. I would start walking them for an hour a day, it doesn’t have to be at a fast pace, especially if they have been inactive and show signs of fatigue, a leisurely walk will do. Go in the morning or evening when it is cool.
PS: Have plenty of fresh water available, if they are not water drinkers add a splash to their meals.
