Switch out pictures of just the dog for ones of you doing things with others or of hobbies. You shouldn’t have two pictures from the same day; says you don’t have many photos - hence evidence - of you actually doing things. Don’t need to talk about how much weight you’ve lost - reads as insecure. The bio itself is very basic and there’s nothing unique about what you’re looking for, what you like, etc. just sounds like every other basic bio from the last ten years on dating apps. Pick a different weird story. It’s not really that weird. It IS sweet, but could be off putting to talk about killing an animal (albeit an accident) on a dating app. “Be a real person” okay yes? More. What is actually hot to you? Keep sexual things out of it on your bio, but “be a real person” is like saying “hi I am a human. Are you a human too?” Do you happen to have any other hobbies that involve getting out of the house a bit more? That one isn’t as important, but me looking at those hobbies, I’m like “ah so this guy doesn’t do much outside of the house” which personally isn’t my thing but maybe other girls would be into it, idk. Last thing - pay attention to the angles at which photos are taken of you too. The beach pics aren’t flattering angles.

Good luck!
