I think all of us have felt that way at one point. It's very frustrating trying to find a responsible breeder, without paying WAY too much. I got my first one from a puppy mill, without knowing what a puppy mill even was. But after I seen him, I have to get him out of there. Trust me, I wish I could have had them all. It was sad seeing them running back and forth in their little crates. No socialization. But I'll tell ya, after time he has been a great dog, and hasnt had any health issues.
But don't worry, your day will come. And you will be happy that you didnt settle. A friend of mine, went and looked at a pup, but it wasnt what she wanted. Sure it was cute, but she had her heart set on a few characteristics. Which the dog did not have.
Anyways, take your time and research as much as you can. And you WILL find your new baby. I promise.
Good luck!
