Me dog got big. I hesitate to say that Rolf the Chihuahua got big but he he did grow a little. Jasna's grown into a nearly perfect dog. Our only big hurdle now is her prey drive. I talked to her breeders about it and they advised reinforcing her pack instinct with obedience training until it becomes mightier than her desire to hunt. If anyone has experience with training high prey drive dogs i would be very interested to hear how you managed it.
