Can I get paid for taking care of my veteran dad? What do I gotta do to apply for those benefits?

So, I've been taking care of my dad (he's a Vietnam vet) pretty much full-time for the past year. It's been tough financially since I had to cut back my work hours. Someone mentioned there might be a way to get paid for being his caregiver through the VA, but I have no clue how to even start with that. Any info would be a huge help - we could really use the extra income.
