Twitter users were obsessed with Evans' actions and gushed over his love for dogs

Fans of Evans know that he loves dogs and has his own, named Dodger, that the Marvel star frequently posts photos and videos of on Twitter.

In 2018, Evans shared a throwback video that showed the moment he met Dodger and decided to adopt him.

"He was trying so hard to stay seated even though he desperately wanted to get out. I knew right away that he was coming home with me, so I took this video to always remember our first hello. Rescue dogs are the best dogs!!" Evans wrote.

The actor also told People magazine in 2017 that he adopted Dodger while filming the movie "Gifted."

"I was walking up and down the aisles and saw this one dude, and he didn't belong there," he said. "I snagged him, and he's such a good dog. They aged him at about 1. He acts like a puppy. He's got the energy of a puppy. He's just such a sweetheart. He's such a good boy. He loves dogs. He loves kids. He's full of love."

Evans added: "He's up for anything. God, dogs, they're such great animals. I really can't say enough about dogs. I'm a dog lunatic. He sleeps on my pillow. You wake up face-to-face."
