St. Petersburg is a city where you can experience three seasons in a single day: drizzle in the morning, sunshine at noon, and a squally wind off the Gulf of Finland by evening. People have adapted — they simply carry an umbrella. Dogs, however, "wear" their weather protection on their own bodies, and it's their coat that takes the first hit from humidity, temperature swings and road chemicals. Here's how the climate of Russia's northern capital affects pets — and why coat care here is a matter of health, not aesthetics.

Humidity: The Number One Enemy of a Dog's Coat in St. Petersburg

The average annual relative humidity in St. Petersburg is around 75–80%; it drops to 60–70% in summer and stays at 83–88% in winter. For dogs with long or double coats, this means one thing: their fur is almost always slightly damp.

Damp fur mats many times faster than dry fur. Tangles form in the "wet zones" — behind the ears, in the armpits, on the leg feathering and the tail. Under a mat, the skin can't breathe and stays moist, and in a humid climate this quickly leads to chafing, dermatitis and fungal problems. What would merely look untidy in a dry climate becomes a medical issue in St. Petersburg.

What to do: after every walk in rain or wet snow, the dog shouldn't just be wiped down but properly dried — with a towel, and for long-haired breeds ideally with a hair dryer on low power. Drying should always be combined with brushing: if matted fur is dried "as is," the tangle sets for good.

Temperature Swings and "Broken" Shedding

Normally, a dog's shedding follows the seasons: the winter undercoat comes out in spring, the summer guard hairs in autumn. But the shedding mechanism is regulated not only by day length — temperature matters too. When it's +8°C and raining in November, there's a thaw in January and a sudden snowfall in April, the dog's body receives contradictory signals.

The result is familiar to many St. Petersburg dog owners: the dog sheds nearly year-round, the undercoat renews itself chaotically, and "dead" hair that didn't fall out on time stays in the coat and acts like felt — trapping moisture and causing the very same mats. For apartment dogs, central heating amplifies the effect: hot, dry air indoors versus dampness outdoors is a daily contrast stress for the skin.

What to do: during a prolonged shedding period, the dog needs to be brushed more often than usual, and breeds with a dense undercoat (Spitz, Samoyeds, Huskies, Corgis) benefit from a professional de-shedding treatment once a season — washing out and blowing out the dead undercoat, which a household slicker brush can no longer handle.

Winter: De-Icing Chemicals Are Worse Than the Frost

St. Petersburg frost itself isn't a problem for most dogs — the problem is what the sidewalks are treated with. Salt and de-icing chemicals corrode paw pads, cause cracks and chemical burns, and the residue licked off the paws ends up in the stomach. The fur between the pads soaks up these chemicals like a sponge, along with snowballs that pack between the toes and injure the skin with every step.

What to do: in winter, paws should be washed after every walk, and the fur between the pads should be trimmed regularly. This is one of those procedures many dogs absolutely hate, so it's often wiser to leave it to a groomer: a bad at-home experience with paw trimming can leave a pet with a lasting fear of any handling.

Summer: Shaving Your Dog Down Is a Bad Idea

When a heatwave hits the city, owners of fluffy breeds are tempted to shave the dog bald "so it doesn't overheat." With a double coat, this works exactly the other way around: the undercoat and guard hairs form an air layer that protects against cold, overheating and UV alike. Shaving destroys this system — the coat may grow back unevenly or be damaged permanently (so-called post-clipping alopecia), while the skin is left defenseless against the sun.

What to do: what helps fluffy breeds in the heat isn't shaving but thorough de-shedding of the undercoat — the "fur coat" becomes lighter and starts ventilating again. Hygienic and styled trims are fine, as long as the protective layer of the coat is preserved.

The Groomers' Take: "In Our Climate, Coat Care Is a Necessity, Not a Luxury"

For a professional perspective, we turned to the St. Petersburg grooming space Chia & Co (Chiya i Kompaniya), whose specialists see dozens of "victims" of the local climate every day.

In the experience of the salon's groomers, St. Petersburg dampness is a constant backdrop to their work. A typical scenario: an owner brings a dog in after autumn "just for a trim," and beneath an outwardly normal coat they find a matted undercoat and irritated skin. Moisture plus an undercoat that wasn't removed in time turns the coat into felt, and sometimes the only humane option left is a short clip followed by coat restoration.

Many of these problems are solved by regularity: groomers generally recommend a full grooming session every 4–8 weeks depending on the breed — a bath with professional cosmetics, complete drying with undercoat blow-out, hygienic paw trimming and nail care. For damaged coats, Chia & Co is developing a SPA line — moisturizing and restorative treatments with therapeutic cosmetics: according to the salon's founder Veronika Puzyan, even a badly damaged coat can realistically be restored within a few months of joint effort by the groomer, the vet and the owner.

The salon puts particular emphasis on stress-free procedures — especially for dogs that already have negative associations with the dryer or with paw trimming after winter "de-icer" burns. The pet is never forced: the staff find a comfortable position, take breaks, use treats for distraction, and in cases of serious fear bring in the in-house dog behaviorist. Puppies are introduced to the procedures gradually — there's a dedicated "first grooming" format for that.

Cheat Sheet: Dog Care by the St. Petersburg Forecast

  • Rain, drizzle, wet snow — dry the dog after every walk, brushing as you go; don't let the coat air-dry on its own.
  • Thaw and slush — wash the paws and belly, watch the zones that collect dirty water.
  • Ice and de-icing chemicals — wash the paws after every outing, keep the fur between the pads trimmed, use protective paw wax or booties.
  • Sudden warming/cooling — step up the brushing: temperature swings trigger unscheduled shedding.
  • Heat — don't shave double-coated breeds; de-shed the undercoat and walk in the morning and evening.
  • Every 4–8 weeks — professional grooming: complete drying, undercoat work, paw and nail hygiene.

St. Petersburg weather is unpredictable, but a coat's reaction to it is entirely predictable. And while an umbrella is enough to protect a human from the damp, a dog needs systematic care: drying and brushing at home, regular professional maintenance at the salon. Then no Baltic cyclone will catch your pet off guard.
