How much should a weimaraner weigh at 6 months?

There's a wide normal range, but many weimaraner puppies have reached a large part of their adult height by six months even though they'll continue filling out with weight and muscle for another year or more. Your vet can assess whether your individual puppy is tracking well.

When does a weimaraner stop growing?

Most weimaraners reach close to full height within the first year but continue maturing in weight and muscle until around 18 to 24 months, which is typical for a large breed and considerably longer than a small dog takes.

Should weimaraner puppies eat large-breed puppy food?

Yes, a large-breed puppy formula is generally the sensible choice, since it's built for steadier, controlled growth appropriate to a big dog's joints, rather than the faster growth formulas designed for small breeds that mature much sooner.

Weimaraner weight chart: what to expect

A weimaraner is a large breed, with adults typically weighing 25 to 40kg depending on sex, and — like most large breeds — it takes considerably longer to reach full maturity than a small dog, often not finishing filling out until close to two years old even after reaching most of its height much earlier.

What a typical pattern looks like

A weimaraner puppy grows quickly in the first six months, often reaching a large share of its adult height by then, but continues gaining weight and muscle more gradually afterward, with full physical maturity typically not reached until 18 to 24 months. This extended timeline is normal for a large breed and is exactly why large-breed puppy food, formulated for slower, steadier growth, matters for this breed specifically.

As with any breed, individual weimaraners vary based on parentage, sex and general health, so a chart shows a general pattern to check against, not a precise target for a specific dog at a specific age.

How to use a growth chart sensibly

Weigh your weimaraner puppy at reasonably regular intervals and track the trend over time rather than reacting to any single weigh-in, since normal growth isn't perfectly linear week to week. A puppy tracking a steady, consistent curve is a better sign than one whose weight looks right on a chart but jumps around unpredictably between checks.

Because weimaraners are a deep-chested large breed, body condition — how they look and feel, not just the number on a scale — is worth assessing at routine vet checks alongside weight, since a chart alone can't tell you whether a dog is carrying appropriate muscle versus excess weight.
