Pregnancy and Whelping Complications in the Bichon Frise

Whelping has intervals that are considered normal and intervals that are not. Writing these down before labour starts is far more useful than trying to judge in the moment.

Two problems dominate small-breed whelping, and they are related to size in different ways.

The first is obstruction. A small litter means each puppy receives a larger share of the available nutrition and can grow bigger, while the birth canal remains small. A litter of two in a 15-pound bitch can produce puppies too large to pass, and that is a surgical situation rather than one that resolves with time.

The second is metabolic. Producing milk draws heavily on calcium reserves, and a small bitch feeding a litter has limited reserve to draw on. If blood calcium falls sharply, the result is a condition that begins as restlessness and panting and progresses to muscle tremors, stiffness, fever and seizures. It usually strikes in the first few weeks after whelping and is a genuine emergency requiring immediate veterinary treatment.

A third consideration is uterine inertia, where contractions simply become ineffective. This is more common in small litters, because the hormonal signal driving labour is weaker with fewer puppies.

None of these is a reason not to breed. They are reasons to have a veterinary relationship established before the mating rather than after labour starts.

If you think your Bichon has pregnancy complications, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers skin allergies, patellar luxation, bladder stones.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for pregnancy complications it is often what separates a clear pattern from a guess.
