I don’t think they’d be fast enough but it depends on the dog. Some puppies are REALLY fast, a lot are clumsy at that age LOL plus at that age they usually want to stay with you. But could always try a light long line.
And yeah that sounds pretty good.

you could do some fetch too on soft ground but not too much as too much repetition can be bad for joints. Puppies love tug too hahah Brewster is obsessed and it’s exhausting.

for him LOL. Wrestling with his toys is exhausting too or chewing on a chew toy or bully stick is too haha and chewing is calming too. Flirt poles are amazing too LOL
Also is he 8 weeks now? He might be 3 months when you get him.
