Endless energy

I’ve got a Dalmatian cross greyhound who’s 18 months old- I know 🥲

He’s got endless energy and I mean endless from the second he wakes up to when he goes to bed. He has 2 x 1 hr walks a day, chews, all his meals in enrichment toys or scattered, we play tug and fetch for at least 30-45 mins a day and he still never seems to run out of energy what else can I do or is it a case of hoping he calms once the teenage phase is over or is this the most energetic mix I could have got and I’m doomed for the next 10 years🤣
