While this might not be possible with pet stores, regardless of their reputation, it will be wise to check the breeder's parent dogs or meet with your puppy's parents, especially if it is an F1 Cavapoo puppy. Your breeder might present genetic health clearances and certificates like OFA and CERF to prove your dog's freedom, but meeting your puppy's parents can give you an overview of your puppy's temperament, appearance, and size.
