My dog has an enlarged heart. What exercise is safe, especially fetch?

Pet's info: Dog | Labrador Retriever | Male | neutered | 10 years old | 70 lbs

I have a 10 year old black lab who has recently been diagnosed with an enlarged heart. We switched him to cardiac dog food and we're awaiting a second vet visit so we can find the right medicine to put him on. What I want to know is how to exercise him. Fetch is his favourite thing and I don't want to take that away from him. I'm trying not throwing it as far resting briefly between throws. Will this work long term... or short term, even?

It is helpful to keep him fit but without overexertion. regular lead walking is preferable as this will not massively increase the strain on his heart, if he is panting or breathless you should reduce the speed and distance. Indoor fetch or playing hide/seek rather than throwing the ball long distance is preferable to repeated sprinting for a toy which can be high intensity exercise
