I think half the time it is accurate and the other half it isn't. Breeding dogs has so many facters. The different lines the pair come from, etc. etc. You can breed a large female with a small male and still get huge puppies. You can breed two 6 pounders and end up with very tiny puppies. IT is a hit or miss. Once you have bred a particular pair you have a better idea of what those two together will produce. The charts have been wrong for all my dogs, every one. My first Chihuahua was charting for 7 pound adult, he is 10. My second female was charting for 5 pound adult, she is 7 pounds. My first female was charting for 6 pound adult and she ended up at 4 pounds. My third female is charting as a 5 pound adult but is only 3.65 pounds at 8 months. My second male is charting at a 5 pound adult and only 2 pounds at 4 months. So it is a crap-shoot in my opinion.
