My dog caught parvo when he was a puppy. He's about to be 3, can he get it again in any way?

It's possible he can get it again, but very unlikely. They usually have long-standing immunity when they recover from parvo and older dogs are less-likely to get it than younger dogs anyways. However, to be safe, it's best to ensure that he is getting his parvo vaccine every three years to ensure his immunity is continually boosted. I hope that helps and all is well with Bowser.
