Where to get a dog? ohio .?

so im getting a dog this weekend. and i have no idea from where. i know this may sound like a really stupid question but the dog we currently have was from our neighbors dog , because it had puppies. I really dont feel like buying one of the internet because ive heard things. or they may be puppy milled. I live in ohio. I know petland and pick of the litter only 2 stores i know in the mall that sells animals. are there any other stores ? or i also know from the animal shelter. is really safe to get one from there ?
