Only the first is good on account of the style and image quality.
Walking the dog could have been good but you look too feminin in your posture and expression and both you and the dog look very skinny. The one on the bench had the right idea but you look like you're cupping your balls with your right hand while watching "something".
My suggestion is go for a pic of you hugging the dog instead. And add some activity photos (music, cooking, sports...) And lose that red shirt because otherwise you do have style
