There are often lots of poodle mixes. You may want to try going through a rescue that has dogs living in actual homes or a shelter that knows a particular dog's background if she will be living with chickens or other animals and children. By being in a foster home the dog can be evaluated as to temperament and whether it gets along with other animals or children or should be an only pet.
Most are priced at $200. to $300, (One place is $500. for a purebred, but I find that excessive), but then the dog is ready to go. It is neutered, up to date on shots, teeth cleaned and any medical problems fixed.
Also, often if dogs are with a foster parent, obedience training has been started so you are ahead of the game.
Other than strays, most of the shelters in our area screen dogs coming in so they have an idea of what would make an ideal home for that particular dog.
Good luck.
