Why do I see a dog with no owner in Houston? I don't know if it's a stray or homeless or something?

It’s happening more than once, and I’m scared to walk now. I don’t want them to approach me

I walk at a place near my house, I just moved here this year, I saw a dog that looked like a wolf today with no owner
