How big do Mini Golden Retrievers get? (2026 Size Guide)

Last updated October 2026 · By Reagan, Golden Raes, Lehi, Utah

Quick answer

Most Mini Golden Retrievers weigh 20 to 45 lb and stand about 14 to 20 inches tall as adults, roughly half the weight of a standard Golden Retriever, which the AKC standard puts at 55 to 75 lb. Golden Raes' multi-generation red Minis currently weigh 25 to 36 lb as adults.

Why do Mini Golden sizes vary so much?

"Mini Golden" describes a type of dog, not a breed with a written standard, so size depends on how each program breeds. A first-generation cross between a 65 lb Golden and a 25 lb Cocker Spaniel can produce puppies anywhere in between. Multi-generation programs, which breed Mini Goldens to Mini Goldens, narrow that range over time.

That is why the most useful number is not a breed average. It is the projected adult weight for a specific litter, based on the size of both parents and how their previous puppies matured. Golden Raes lists a projected weight on every litter. For reference, Nike weighs 25 lb, George 36 lb and Air about 25 lb.

How does a Mini Golden compare to other Golden-type dogs?

Adult size comparison
	Weight	Height at shoulder
Golden Raes Mini Golden (our current dogs)	25–36 lb	Up to 19 in
Mini Golden (general range)	20–45 lb	About 14–20 in
Mini Goldendoodle	25–35 lb	14–17 in
Standard Golden Retriever, female	55–65 lb	21.5–22.5 in
Standard Golden Retriever, male	65–75 lb	23–24 in

Standard Golden sizes are from the AKC Official Standard. Mini Golden ranges are from Dog Academy, and Mini Goldendoodle figures are from Happy-Go-Doodle.

When do Mini Golden Retrievers stop growing?

Standard Goldens reach most of their adult height by 9 to 12 months and keep adding muscle and weight until about 18 to 24 months, according to iHeartDogs' growth data. Smaller dogs generally finish growing a bit sooner, so expect a Mini to reach most of its height in the first year and fill out over the months after. Your vet will track growth at each checkup.

How can you predict your puppy's adult size?

Ask for both parents' adult weights. This is the single best predictor.
Ask how earlier litters from the same pairing matured.
Look at the DNA breed breakdown. More Golden Retriever in the mix usually means a bigger dog.
Use the breeder's projection for that litter, not a general breed range.

Apply for a puppy

What size crate and gear does a Mini Golden need?

Buy for the adult dog, not the puppy. A crate should let your grown dog stand up, turn around and lie down stretched out, and most 25 to 36 lb dogs fit a crate around 30 to 36 inches long. Check the maker's weight chart, and use a divider while your puppy is small so the crate doesn't double as a bathroom. A medium harness and collar will fit a grown Mini, with a small set to get you through puppyhood.

Is a 25 to 36 lb dog the right size for your family?

For many families it is the sweet spot. A dog this size fits in a back seat with car seats, is easy to lift into a tub or onto a vet table, and eats far less than a 70 lb Golden. It is still sturdy enough for hikes, fetch and rough-and-tumble play with kids. If you want a Golden's personality without a Golden's size, this is the reason Mini Goldens exist. Our family dog guide covers temperament and exercise.
