For owners who have chosen not to spay their female dog (see our dedicated article on neutering and spaying to weigh the pros and cons), managing heat periods requires specific organisation roughly twice a year.

The heat cycle

Heat generally occurs every 6 months, with variations depending on breed and individual, and lasts around 3 weeks, broken down into several phases with varying levels of receptiveness to mating.

Signs to recognise

  • Swelling of the vulva
  • Bloody discharge, gradually becoming lighter over the course of the cycle
  • Behavioural changes: some females become more affectionate, others more irritable or nervous
  • Increased attraction of males, even from a considerable distance

Practical day-to-day management

Preventing escapes

A female in heat may actively try to escape to reach a male — increased vigilance around fencing and leashed walks is essential throughout the entire period.

Managing walks around other dogs

Encounters with unneutered males should be anticipated and avoided if pregnancy is not desired, including at sport clubs or during usual walks.

The female's comfort

Protective pants exist to limit discharge on furniture or surfaces, without disturbing the female's everyday comfort.

The impact on physical and sport activity

For a female regularly practising dog sport (see our articles on canicross, agility or competition obedience), the heat period can come with a temporary drop in motivation or concentration — a temporary adjustment to the training programme is generally preferable to counterproductive insistence.

Phantom pregnancy: a common phenomenon after heat

Some females develop signs of phantom pregnancy a few weeks after their heat (mammary swelling, maternal behaviour towards objects) without an actual pregnancy — a generally benign phenomenon that nonetheless deserves veterinary monitoring in cases of pronounced or recurring symptoms.

A decision to make with full knowledge of the facts

As mentioned in our article on neutering and spaying, managing repeated heat cycles over several years carries its own constraints and health risks (pyometra in particular) — a factor to fully weigh when considering whether spaying is the right choice.
