Coton de Tulear weight chart
A fully grown Coton de Tulear typically weighs somewhere between 3.5 and 6kg, standing around 25 to 32cm at the shoulder, and — like most small breeds — reaches close to its adult size fairly quickly, usually by around nine to twelve months old.
Reading a Coton's growth curve
Small breeds generally do most of their growing in a shorter window than medium or large dogs, and Cotons follow that pattern closely — rapid growth through the first few months, tapering off well before their first birthday, with most of the size difference between individual dogs coming down to genetics rather than anything an owner does differently.
A Coton at six months is usually already close to its adult height, even if it takes a little longer to fill out fully through the chest and develop its full, plush coat, which for this breed is as much a defining feature as its size.
What affects where a Coton sits in that range
Parentage plays the biggest role in where an individual Coton lands within the 3.5 to 6kg range — a puppy from smaller parents will typically stay smaller regardless of feeding, and there is no benefit to trying to push a naturally small dog toward the top of the breed's range.
Because Cotons are a genuinely small breed, body condition is easy to check by hand — feeling for the ribs under that dense coat and looking for a waist — and it is a far more useful measure of health than the number on the scale on its own, particularly given how much the coat can visually disguise a dog's actual shape underneath.
When a Coton's weight is worth a second look
A sudden change in weight, in either direction, is more informative for a small breed like this than for a larger dog, since a shift that would barely register on a large dog's scale can represent a meaningful percentage of a Coton's total bodyweight.
If your Coton seems to be gaining or losing weight noticeably without a clear reason, or if its normal energy and appetite change alongside it, that combination is worth raising with your vet rather than adjusting food on your own and waiting to see what happens.
Common questions
- How much should an adult Coton de Tulear weigh?
- Most adult Cotons weigh somewhere between 3.5 and 6kg, standing roughly 25 to 32cm at the shoulder. Where an individual dog sits within that range comes down mostly to genetics and parentage rather than diet or exercise.
- When does a Coton de Tulear stop growing?
- Like most small breeds, Cotons reach close to their adult height fairly quickly, usually by around nine to twelve months old, though filling out through the chest and developing the breed's full coat can continue a little beyond that.
- How can I tell if my Coton is a healthy weight under all that coat?
- Feel for the ribs by running your hands along the sides rather than relying on how the dog looks visually, since the dense coat can disguise the actual shape underneath. You should be able to feel the ribs without pressing hard, and feel a waist behind them.
