looking for a stud dog

I’m looking for a black lab male with a built that’s like a pointer, so more lean and tall,rather than a stocky build. My bitch is already in heat, so I’m looking for someone that’s ready to go now. I’m located in Iowa, so that is preferred. I don’t know how stud services work but am very willing to learn and hope someone can help me out. I’m not registered with AKC, but not opposed to using a dog that is. My email is [[email protected]](mailto:[email protected])
