Size is one of the most important factors to consider when adopting a puppy. Do you want a small dog that will fit on your lap, or a large dog that you can take hiking and camping? Or perhaps you want something in between — a medium-sized dog that is the best of both worlds?
Before bringing a puppy home for good, it’s important to know what you’re getting into. Your dog’s eventual size will have an impact on their exercise needs, grooming requirements, and cost. So how can you figure out how big your dog will get? Let’s take a look at answering the question, “How big will my dog get?”
Estimating the Final Size of a Purebred
Estimating the final size of a purebred dog is not all that difficult. You can get a good idea by looking at the pup’s parents and at breed standards on the American Kennel Club’s website, where you’ll find each breed’s typical weight range, height, and more.
Measuring Mixed Breeds
Figuring out the final size of a mixed breed pup can be more tricky, especially if you adopt a dog from a shelter and the dog’s breeds, age, and parents’ sizes are unknown. However, there are some ways to estimate a pup’s growth potential, outlined below.
There are certain considerations that can help you project your pal’s eventual size:
- Look at the breed and size of both parents. If the parents are the same breed and around the same size, you can get a pretty good idea of how large your dog will grow. If the parents are different breeds and different sizes, the bitch’s size will have more influence on your pup’s eventual size than the sire’s.
- Some suggest that you can estimate your pup’s size by doubling their weight at 4 months old. For giant breed dogs, double their weight at 5 months instead.
- While it’s not an exact science, looking at your pup’s paws can help you predict their final size. A pup with petite paws isn’t going to grow to a weight they can’t support, and a dog with large, floppy paws isn’t going to end up a dainty puffball.
- Height vs. weight: a dog will stop growing in height before it stops growing in weight. Most dogs will be at 75% of their final height at around 6 months old, but they can keep putting on weight for another 6 months to another year, depending on the breed
When Do Dogs Stop Growing?
The answer to this question depends on a number of factors, including size and breed. In general, small breed dogs stop growing sooner than large breed dogs. This will help answer your question of “How big will my dog get?” and give you ample time to prepare.
- Toy breed dogs (like Chihuahuas and Yorkshire Terriers) generally reach their full size between 10 months and 1 year.
- Small to medium sized dogs (like Beagles and Basenjis) will reach their final height between 12 and 15 months, and their final weight by 18 months.
- Medium and large breed dogs (like Collies and Golden Retrievers) are full grown by around 18 months, and reach their final weight at around 2 years.
- Giant breed dogs (like Great Danes and Irish Wolfhounds) may grow into their bodies by 18 months old, but it could take up to 3 years for them to reach their final weight.
