Usually you can take the weight at 12 weeks and double it to come up with a guesstimate on weight. My oldest yorkie, Rasta, parents are 6lbs(dam) and a little over 4lbs(sire). Rasta's a whopping 2.5 lbs right now. Smaller than both his parents and grandsire/dam. I would look at past litters with that particular bitch/dog to get a better idea of what sizes they throw, but you still may be surprised lol. |
