A Bichon is a small dog wearing a very large disguise
The Bichon Frise's double coat is groomed to stand out from the body in a rounded cloud, which means the silhouette you see tells you almost nothing about the dog inside it. A Bichon can be carrying clearly too much weight while still looking like the same cheerful powder puff, and a freshly clipped Bichon can look startlingly different from the same dog a month later with no weight change at all. For this breed the hands-on check is not a backup method; it is the only method that works.
Feeling for ribs, waist, and tuck
Part the coat with your fingers and lay flat hands over the ribcage behind the front legs. You should feel the ribs readily, with a light covering that lets them move under your palms as the dog breathes. If you have to press and search, there is padding in the way. Run your hands from the ribs back toward the hips to feel for a narrowing at the waist, then part the coat along the belly or check during a bath to see whether the tummy tucks up a little toward the hind legs. A Bichon whose body feels like a uniform padded tube from shoulders to hips, with no waist you can find, is telling you the answer even though the mirror will not.
Small dog, small margins
Scale matters enormously here. An amount of weight that would be trivial on a large breed represents a substantial fraction of a Bichon's whole body, and it loads small joints, a small airway's worth of stamina, and a small frame accordingly. That is also why Bichons gain so easily: one extra treat a day, a slightly heaped scoop, or regular tastes of family dinner are proportionally huge. Weigh your Bichon regularly — many can be weighed on home scales by holding the dog and subtracting your own weight — and treat a steady upward creep of even small amounts as real information, not rounding error.
The Bichon routes to extra weight
This is a companion breed that lives at the centre of household food life: under the table, beside the sofa, and first in line when anyone opens a cupboard. Clever, appealing begging is practically a breed trait, and several family members each giving a little creates a lot. Grooming appointments can also mislead — a dog who looks slimmer after a short clip has lost hair, not weight. Measure the actual food, set a household rule that treats come only from a small daily pot taken out of the meal allowance, and use play, fuss, and short training games as rewards, because a Bichon usually values attention as highly as food.
When to ask your veterinarian
Book a check if you cannot find the ribs or waist by feel, if the scale keeps rising across two or three weigh-ins, or if your Bichon is panting more, tiring on short walks, snoring newly, or struggling with stairs — small dogs hide discomfort until it is well established. Ask for a target weight suited to your dog's individual frame, since Bichons vary, and a precise daily food amount in grams rather than cup estimates. If weight climbs despite careful measuring, your veterinarian can check for underlying causes before the diet gets ever tighter. Recording each weight, bath-day body check, and agreed target in KinsLe in the Pet Passport turns easily forgotten small numbers into a clear story your veterinarian can act on.
