How Big Will My Puppy Get?

So, how big will my puppy get? This is a question many first-time dog owners will ask or even anyone that has just added a new puppy to their home. No one can ever promise you what size your puppy will grow if anyone promises you a specific weight your puppy will grow to, think again. An honest breeder will typically give you a range in size/weight, but will never promise you the exact size of your puppy. The best estimate you can get for trying to guess how big your puppy will be fully grown is taking the average weight of the Sire & Dam (Mom & Dad) of the puppy in question. For example: If the puppies mom weights 30 pounds, and the dad weighs 24 pounds, the best guess you could take is that your puppy would be about 27 pounds, but at LEAST would most likely be between 24 & 30 pounds full grown.
It is also important to take note that weight can be different with different breeds, a poodle that weighs 12 pounds, can be as tall as a cocker spaniel that weighs 30 pounds. Each dog has a different build which would make size and weight technically 2 different factors! With some puppies you will find, males tend to be at least a little bit bigger than females, but sometimes not. The specific momma dog would determine that exact answer based on past trends from her past litters.
What if I have no way to get the Sire & Dam of the puppy’s weight?
There is another simple, but sometimes effective way to figure out the full-grown size your puppy could be around by using a simple math equation.
Even then, this math equation is not ALWAYS accurate but still might give you more of a hint of adult weight than you currently know.
The way you do this take the weight of the puppy around 8 weeks to 10 weeks of age, and multiply that number by 3. If your puppy weighs 4 pounds around the age of 8 weeks old, your puppy will most likely be around the 12-pound mark fully grown.
The image below is a fun way to see how long it takes for each size dog on average to finish growing, larger breeds can take up to 18 months to be fully grown when smaller “toy” size dogs can be fully grown around the age of 9 months old! Even when your dog is at the “fully grown” size, they still might add a few pounds as they slow down on growing and start filling out a little bit.
