Add the heights of your dog's sire and dam together, then divide by two. This will give you the median height of a litter born to those dogs, providing you with an idea of what height yours will be when full grown.This is only possible if you have access to the heights of your dog's parents.
Add the weights of your dog's sire and dam together, then divide by two. This will give you the median weight of a litter born to those dogs, providing you with an estimate of your dog's adult weight. This is only possible if you have access to the weights of your dog's parents.
Wait until your teacup dog's initial growth stage begins to slow, which is normally around 12 weeks old.
Weigh your puppy using a scale that can measure in ounces, since teacup dogs tend to be very light and you need to know a specific weight for the formula being used.
Divide the puppy's weight measurement by its age in weeks when you took the weight. If your dog is 12 weeks old and weighs 1.3 lbs., divide 1.3 by 12. This results is 0.11, which is the puppy's growth weight of pounds per week.
Multiply the growth rate by 52, the number of weeks in one year. A growth rate of 0.11 lbs. per week times 52 weeks equals 5.72 lbs. This is your weight estimate for your puppy at one year old, which is when most toy dogs are considered full grown.
