Am i doing enough? is it a dog's life for them?

You're doing plenty, sounds like they get plenty of exercise and interaction, you're lucky you can take them with you to work, they get to play and run with toys and grooming, sounds like you do more for your dogs than most people who leave them home alone for 10 hours and give them a 20 minute walk. Sounds like it's good to be a dog in your home.
