Decomposed granite in backyard?

[Arjun K.]

I purchased a rental (duplex, each unit is $1k/month). The tenants in both units want to reseed the backyard. One has suggested putting decomposed granite for half the lawn, and then grass for the 2nd half. This is because they claim its lower maintenance and they have a dog -- so more pet friendly.

I have no idea. Any thoughts? What are future maintenance concerns? the cost seems reasonable enough.

Thank you!
