Mini Sheepadoodle Size and Weight with a Helpful Chart

Thinking about bringing home a Mini Sheepadoodle? You’re probably wondering how big they get and how fast they grow.

This guide covers typical size and weight ranges, a month-by-month Mini Sheepadoodle growth chart, and practical tips to keep your pup at a healthy weight. Use the chart as a helpful reference—then let your individual dog lead the way. (Every doodle writes their own script!)

A Mini Sheepadoodle is a cross between an Old English Sheepdog and a Miniature Poodle (often via an F1 or F1b pairing). Compared with Standards, Minis are more apartment-friendly and easier to lift into the car, yet they keep that goofy, people-pleasing temperament.

Most Mini Sheepadoodles full grown land in the 25–40 lb range and around 15–18 inches at the shoulder, but genetics can nudge them a bit smaller or larger.

Mini Sheepadoodle Size and Weight Chart by Age

These are average ranges—some puppies will be ahead or behind and still end up perfectly healthy. If your pup sits outside these bands for more than a month, ask your vet or breeder for guidance.

Quick tip: a steady, slow-and-sure curve is the goal. Rapid jumps can stress growing joints.

How to use the chart

Track weight weekly to monthly and look for smooth progress. If your pup is a consistent outlier, check in with your vet and breeder—especially if you see sudden jumps or stalls.

Factors That Influence Mini Sheepadoodle Size

• Genetics: The size of the Poodle parent (and whether there’s a “small standard” in the mix) heavily influences adult size.

• Generation: F1 vs F1b vs multigen pairings can change predictability—breeders may have better estimates when they’ve produced several similar litters.

• Sex: Males trend slightly larger than females.

• Nutrition & Activity: Appropriate calories, quality protein, and steady exercise support healthy growth without packing on extra pounds.

When Do Mini Sheepadoodles Stop Growing?

Most Minis reach their adult height by ~10–12 months, then fill out (muscle + a bit of fat) until 12–18 months. Big spurts often appear around 4–6 months and again near 7–9 months. Males sometimes add a few extra pounds toward the end of that window.

How to Estimate Your Puppy’s Adult Size

A good way to estimate your Mini Sheepadoodle’s adult size is by using the 16-week rule of thumb—simply weigh your puppy at four months old and then double that number for a ballpark idea of their full-grown weight.

You can also track progress with percent-of-adult checks. By around six months, most Minis have reached about 60 percent of their adult weight, and by nine to ten months, they’re usually closer to 75 to 90 percent.

For the most accurate prediction, lean on breeder insight. Experienced breeders often know what to expect based on the weights of the parents and full siblings, and multigen breeders in particular can usually predict within a much tighter range.

Caring for a Growing Mini Sheepadoodle

Feeding: Choose a puppy-appropriate diet from a reputable brand. Use your bag’s calories per cup to set portions, and keep treats to ~10% of daily calories. You should be able to feel ribs easily (not see them) and notice a light waist “tuck.”

Exercise: Daily movement matters, but keep it low-impact while growth plates are open. Short walks, play, training games, and soft-surface fetch are great. Save long stair climbs and repetitive jumping for later.

Joint & Weight Health: Growth that’s too fast or extra weight can stress hips and shoulders. Stay in your chart’s range, use slow feeder bowls if your pup gobbles, and check body condition monthly. When in doubt, your vet is your best co-pilot.

FAQs About Mini Sheepadoodle Sizes & Weight

1) How big will my Mini Sheepadoodle get? Most end up 25–40 lb and 15–18 inches tall. Genetics and sex can push a bit smaller or larger.

2) At what age is a Mini Sheepadoodle full grown? Height often finishes by 10–12 months; weight and muscle fill in until 12–18 months.

3) What if my puppy is below (or above) the chart? Charts show averages. If your pup consistently sits outside the range—or has sudden jumps/dips—chat with your vet and breeder.

4) How can I tell if my Mini Sheepadoodle is overweight? You should feel ribs without digging, see a slight waist from above, and a gentle tummy tuck from the side. If not, scale back portions and add low-impact activity.

5) Do Mini Sheepadoodles stay small compared to Standards? Yes. Minis are typically half the size (or less) of Standards, making them easier to manage in smaller homes and cars.

Mini Sheepadoodles tend to land in the 25–40 lb neighborhood with compact, athletic frames. Use the size and weight chart as a guide, keep an eye on steady progress, and tailor food and exercise to your individual pup.
