My boy Neeko is almost 5 months (he has been with me for 2 weeks) He loves to play tug and chase his balls inside the house but loses all energy and playfulness when we go outside. I would love to play outside because there is so much more room for him to be able to run and for us to play and throw balls. He will swim but isn't interested in toys with water either. Is he just hot or overwhelmed? He doesn't really explore vs playing he more just gets lazy and waits for us to go back inside.
