When i had lots of dogs at home id take them out for long walks and it could be hectic since there was two extra large and one large dog. I will go for walks through the park and play with the dogs doing things such as throwing a Frisbee or a ball and having them fetch. Maybe even play a little tug of war or running around the back yard. Dogs always seem to love belly rubs along with scratching the ears and cuddling while relaxing or sleeping. The pets will enjoy getting some energy out as well as some cuddles if they enjoy those as well. Depending on house if pets are allowed on couch they like to pretend the human is a jungle gym and climb all over which is fun even if they ate big.
