Why Is My Labrador So Itchy and Losing Hair?

Short answer: A Labrador that's itchy and losing hair usually fits one of a few patterns: a young puppy with patchy hair loss around the eyes or muzzle, heavy shedding around six to eight months as the adult coat comes in, or a recurring rash, hot spot or infection in an older dog. Labradors are genuinely more prone to skin trouble than some breeds — a dense double coat that holds on to moisture, and a higher rate of both allergic skin disease and thyroid problems. VitalPaws' pre + probiotic powder is daily gut support, dosed by your dog's weight (usually 2 scoops a day for a Labrador), not a skin treatment — and we don't yet have Labrador-specific results to share. If the skin is broken, there's a sudden bald patch with pus, or your dog is unwell, skip this guide and get to a vet today.

When it's an emergency — go straight to a vet

Most itching and hair loss in a Labrador can wait for a routine vet visit. A few signs can't:

• Skin that's broken, bleeding, or has a sudden bald patch with pus or a strong smell underneath
• Your dog is shaking its head or pawing hard at an ear
• Your dog is off food, feverish, or generally dull alongside the itching
• Nothing has changed after 30 days of a full, vet-guided routine

Any of these needs a same-day clinic visit, not a wait-and-watch at home.

Why Labradors are more prone to this than some breeds

This isn't in your head. Two things make Labradors more likely to show up with itchy, thinning skin:

Their dense double coat holds on to moisture longer than a shorter, single-coated breed's — after swimming, a heavy monsoon coat, or a mat left too long — which is exactly the setup for acute moist dermatitis, better known as a hot spot: a patch of skin that goes red, raw and painful within hours and spreads fast if it isn't caught early. Labradors are also seen often for canine atopic dermatitis (an allergic skin condition triggered by everyday things like dust mites or pollen) and flea allergy dermatitis, and the breed carries a higher-than-average rate of hypothyroidism — an underactive thyroid gland. Hypothyroidism looks different from an allergy: it causes symmetric hair thinning and a dull, brittle coat with little to no itching, usually alongside weight gain and low energy, and it's confirmed with a blood thyroid panel, not a skin exam.

Puppy hair loss and heavy shedding: what's normal, what's not

A young Labrador losing hair in patches — especially around the eyes, muzzle or front legs, with little to no itching — is the classic presentation of localised demodectic mange: an overgrowth of Demodex mites that live in small numbers on every dog's skin and occasionally get out of hand in a puppy's still-developing immune system. It's confirmed with a simple skin scraping, and many localised puppy cases are managed well once a vet is involved — but that call belongs to a vet, not a wait-and-see at home.

Heavy shedding around six to eight months, on its own, with no bald patches, redness or scabbing, is usually just the puppy coat "blowing out" as the adult double coat comes in — normal, not a skin disease. What separates the two is whether the skin underneath looks clean or angry.

Recurring rashes, red bumps and hot spots in an older Labrador

A rash or pimples that keeps returning in an adult Labrador is usually one of three things: pyoderma (a bacterial skin infection, often secondary to scratching or an underlying allergy), an allergic reaction such as flea allergy dermatitis or canine atopic dermatitis, or a hot spot flaring up around a damp or matted patch of coat. A vet visit for a repeat case typically means skin cytology (a sample looked at under a microscope), a flea check, and — if the pattern keeps coming back with no clear trigger — a conversation about an elimination diet trial. Guessing which of these it is from home rarely fixes it for good, because each needs a different vet-directed treatment.

Where daily gut support fits — and the honest limits

A large part of a dog's immune system sits in and around the gut, which is why gut balance and skin reactions are often linked — it's one reason daily gut support can sit alongside a broader routine. But a hot spot, a thyroid problem or a recurring infection is its own condition with its own diagnosis and its own vet-directed treatment; a feed supplement doesn't stand in for that.

Your dog	Daily dose	One 120g pack lasts
Up to 10 kg	½ scoop	about 30 days
11–25 kg	1 scoop	about 15 days
26 kg and above (most adult Labradors)	2 scoops	about a week

Dosing is by weight, not breed, so a lean 22 kg Labrador and a heavier 32 kg one land in different bands — see the full dosing guide by weight. We're a young brand and don't yet have enough Labrador households on file to publish breed-specific results, so we're telling you that plainly rather than making a number up. If your Labrador is already on a vet-prescribed treatment for its skin, keep giving it exactly as directed — the powder is a feed supplement, not a medicine. Every order includes a 1:1 vet teleconsult with Dr. Anvesh Chakravarthy, B.V.Sc & A.H., PetPulse Clinic — mention the itching or hair loss there. For the wider picture on itch causes across breeds, see our guide on why dogs keep scratching, the causes ranked.
