When do Maltese puppies finish growing?

Published October 27, 2026

The short answer

A Maltese puppy finishes growing by about ten to twelve months, reaching his full tiny adult size of under 7 pounds and roughly 7 to 9 inches tall. Because he completes growth so early and stays so small, weigh him monthly on an accurate small scale and take even a few ounces of change seriously. Sharing his feeding amounts, grooming schedule, and weight notes through KinsLe Family Sharing keeps every family member caring for your Maltese working from exactly the same small-dog details.

The Maltese growth story, start to early finish

Maltese puppies are among the fastest-finishing growers in the dog world. Born weighing a few ounces, they multiply their size through the first six months, reach close to their adult height of roughly 7 to 9 inches by about eight months, and are essentially full grown by ten to twelve months. The finished article is a dog of under 7 pounds in the breed standard, with many pet Maltese settling between 4 and 7 pounds. Coat, character, and confidence continue to develop after the body stops — that glorious white coat can take well over a year to reach its full adult glory — but the frame itself is done early.

Small size, fast plates, early decisions

Toy breeds close their growth plates months before large breeds do, which compresses every growth-stage decision into the first year. The move from puppy to adult food typically comes around nine to twelve months for a Maltese. Neutering conversations, adult exercise expectations, and the final assessment of his bite and knees all happen while a Labrador the same age is barely halfway grown. Owners who have previously raised bigger dogs often miss these windows simply because the Maltese looks like a perpetual puppy; keep his actual age, not his appearance, in charge of the schedule.

Feeding a stomach the size of a teacup

A Maltese puppy's stomach is genuinely tiny, so he needs small meals served often — three to four times daily when young, settling to twice daily as an adult. Regular meals matter beyond growth: very small puppies can see their blood sugar dip if they go too long unfed or burn a meal's worth of energy in frantic play. Serve a diet sized for toy breeds so the kibble pieces suit a small mouth, measure the daily amount rather than eyeballing it, and remember that at this scale a single large dog treat can equal a quarter of his day's food. Recalculate honestly when treats have been flowing freely.

Weighing what the white coat conceals

That floor-length white coat is a master of disguise: it makes a lean Maltese look plump and can hide a genuinely thin one. Weigh him monthly on a kitchen or postal scale, keeping a simple written record, and feel for his ribs under the hair whenever you groom — they should be present under a light, smooth covering. Sudden changes in either direction deserve attention at this size. A Maltese who drops weight may be eating around a sore retained baby tooth; one who gains steadily is usually receiving more food, across all his admirers combined, than anyone realises.

Toy-breed growth checks worth the vet's eye

Mention it promptly if a Maltese puppy has episodes of wobbliness, trembling, or unusual sleepiness, especially around a missed meal, since tiny puppies manage low blood sugar poorly. Retained baby teeth are very common in the breed — adult teeth, particularly the canines, often erupt beside the baby set — so ask the veterinarian to check his mouth at every puppy visit and plan any needed extractions before crowding causes trouble. Loose kneecaps are another toy-breed item the vet will feel for as he grows; tell them if you ever see him skip a step with a back leg.

One tiny dog, many carers, one shared record

Maltese are portable, popular houseguests, and family members, partners, and sitters may all feed or groom one small dog in a single week. At under seven pounds, a duplicated meal or a skipped one is proportionally huge. KinsLe Family Sharing lets a Maltese's profile and care information be shared with the family members who help look after him, keeping his portions, weights, and grooming notes identical for everyone who picks him up.
