Guides
Straight answers about how dogs grow, with the veterinary sources cited and the uncertainty stated rather than smoothed over.
How Much Exercise Does a Puppy Need?
Five minutes per month of age is real advice from a real organisation. The Royal Kennel Club publishes it. It also publishes it with no citation, calls it a rule of thumb, and the PDSA says plainly there is no scientific evidence behind it. Here is what has actually been measured.
What Counts as a Large Breed Dog?
Nobody official defines it. We read the rulebooks of five kennel clubs and the guidelines of four veterinary and industry bodies. "Large" starts anywhere from 45 to 70 pounds depending on which document you open, and the Labrador's own breed standard calls it medium-sized.
Do Big Paws Mean a Big Dog?
Nobody has ever tested it in dogs. But the observation behind it is real: every puppy has proportionally large paws, because paw bones finish growing months before leg bones do. That is a fact about all puppies, not a signal about which one ends up big.
Which Foods Are Actually Dangerous to Dogs?
Popular lists run to twenty foods. The Merck Veterinary Manual recognises seven, and only two come with a real dose-response in dogs. Here is every food sorted by how strong the evidence is, including the one that killed 23% of dogs in its largest case series and appears on almost no list.
How Big Do Goldendoodles Get?
Goldendoodle size categories come from a breeder club, not a breed standard, and the club that wrote them says a breeder's estimate is an educated guess. What the categories are, why the genetics makes a doodle so much harder to predict than a purebred, and what nobody has measured.
How Many Calories Does My Dog Need a Day?
FEDIAF's own review of the research puts published feeding allowances anywhere from under 90 to about 200 calories per kg of metabolic bodyweight, a 2.2-fold span for the same dog. Here are the actual published tables, why the guidelines run high, and the two details that matter more than the formula.
My Puppy Is Smaller Than Average: Should I Worry?
Most small puppies are simply small, and the published guidance says so: any centile line on a growth chart can be a healthy weight. What deserves your attention is a change in pattern, not a low number. Here is that difference, the medical causes worth knowing, and the question the research has never answered.
Puppy Weight by Week, for 13 Popular Breeds
Expected weight at each week of age for thirteen of the most popular breeds, generated from our published growth model rather than copied between websites. Plus the thing a weight chart cannot tell you, and why the line your puppy traces matters more than any single number.
Does Neutering Affect How Big My Dog Gets?
Neutering before the growth plates close does change a dog's adult size. It just works the other way round from what most people believe, and it moves height far more than weight. Here is what each study actually found.
How to Tell If Your Puppy Is Overweight
Body condition scoring is the standard method, it takes thirty seconds, and it was validated in adult dogs. Here is how to do it with your hands, how accurate it really is, and what the veterinary literature says to use alongside it on a growing puppy.
Why Large-Breed Puppies Need Different Food
Large-breed puppy food is defined by a calcium maximum, not a calcium minimum, and the size that triggers it is a labelling decision, not a biological one. What the rule says, what the studies measured, and which part of the usual explanation we could not verify.
How Much Should I Feed a Growing Puppy?
There is a published equation for what a growing dog needs, and the best test of it found that it overfed puppies at every age measured. Here is the sum, the three published schedules that disagree with each other, and why body condition has to be the thing you steer by.
How to Predict a Mixed-Breed Puppy's Size
Four ways to estimate a mixed-breed puppy's adult size, ranked by how reliable they actually are, plus the reason every estimate for a mix carries more uncertainty than the same estimate for a purebred.
Puppy Growth Chart by Size
Month-by-month puppy growth charts for toy, small, medium, large and giant breeds, showing what percentage of adult weight to expect at each age, and how to tell a normal curve from one worth asking your vet about.
Rapid Growth and Joint Problems in Large Breeds
"Growing too fast causes joint problems" is half right, and the wrong half gets repeated more often. What the controlled feeding trials really measured, why the pathology literature rejects the osteochondrosis version, and which popular advice has no evidence behind it at all.
When Do Puppies Stop Growing?
Puppies stop growing between 6 and 24 months depending on adult size, but "fully grown" means three different things that happen at three different times. Here is what the veterinary evidence actually says.
