Is it seasonal, fleas, or food?
Work Out What’s Behind the Itch
Timing is often the biggest clue of all. Dogs and cats with atopic (environmental) allergies tend to follow the Australian pollen and grass calendar: symptoms build through spring, peak over a hot, humid summer, and ease off once the weather cools in autumn and winter. If your pet’s itching has a clear on-season, off-season rhythm — worse from around September to April, quieter through the cooler months — an environmental trigger such as grass, pollen, or dust mites is the more likely explanation, although flea allergy dermatitis can produce an almost identical seasonal pattern in warmer parts of the country.
Food-related itching tends to break that rhythm rather than follow it. Instead of building and fading with the seasons, it usually shows up as a background level of scratching, paw chewing, or skin irritation that persists through winter just as much as summer, sometimes alongside softer stools or more frequent bowel motions. A useful check is to think back over the past twelve months: if the honest answer is “it’s always there, just sometimes worse” rather than “it only happens at certain times of year,” a food sensitivity is worth ruling in rather than waiting for the next flare to confirm a seasonal cause.
Because the two patterns can overlap — a food-allergic pet can still get worse during flea season, for example — a short symptom diary noting when the itching started and how it has tracked across the months gives an online vet a far clearer picture than a single snapshot. That history, combined with your pet’s breed and where on the body the itching is worst, is often enough to point toward the likely cause and the right next step.
- Itching that flares up in spring or summer
- Itching all year round with no fleas seen
- A hot spot appearing within hours
- Recurring ear infections alongside skin flares
- Constant paw licking or chewing

How Seasonal and Flea Allergies Show Up
Different triggers tend to produce slightly different patterns — here’s what vets look out for.
Itching That Tracks the Weather
Worse in warm, humid months? That often points to grass, pollen, or flea allergy dermatitis rather than food. Look for redness around the face, ears, armpits, and between the toes — the classic map of an environmental flare.
Red, Broken or Weepy Skin
Hot spots (acute moist dermatitis) can appear and spread within hours in humid weather and often need prompt attention. The patch is typically red, moist, and rapidly spreading, and can double in size within a day if left unmanaged.
Constant Paw Licking or Chewing
Paw and belly licking is a classic sign of atopic dermatitis, and can also point to a food-related allergy. Licking concentrated on the front paws and face leans toward atopic dermatitis, while itching spread evenly over the whole body raises the chance of a food trigger.
Seasonal, Flea, and Food Allergies — What’s the Difference?
Skin symptoms can have different causes. An online vet can assess your pet’s history, symptoms, and photos to guide the safest next step.
Atopic & Seasonal Triggers
Environmental allergies build up through repeated exposure to the same triggers each year, which is why the itch tends to reappear like clockwork:
- Grass, pollen & dust mites (atopic dermatitis)
- Contact irritation from grass or fabrics
- Breed predisposition (Staffies, Westies, Labradors)
Secondary Skin Infections
Persistent scratching breaks down the skin’s natural barrier, leaving an open door for bacteria and yeast to move in — these secondary infections are often what turns a manageable itch into a sore, smelly, or crusted patch that needs its own course of treatment.
- Bacterial infections from broken, scratched skin
- Yeast infections (Malassezia), common in skin folds and ears
- Often follow, not cause, the original itch
Food Allergy vs Environmental Allergy
Both can cause itching, redness, and hair loss, so vets lean on timing and pattern — not just the itch itself — to tell them apart:
- Food allergies: usually itch year-round, not seasonal
- Environmental allergies: often flare with the seasons
- Golden Retrievers and French Bulldogs are commonly affected
- Stress or anxiety can worsen itching, though it is not the primary cause
Flea Allergy Dermatitis
A single flea bite can trigger days of intense itching in an allergic pet, even if you never spot a flea on their coat or bedding:
- A leading cause of itching in dogs and cats
- Worse in warm, humid months
- Needs year-round prevention, not just a summer treatment
A seasonal pattern is a useful clue, but only a vet consultation can confirm whether it’s atopic dermatitis, fleas, food, or a secondary infection.
Getting this right from the start avoids weeks of guesswork.

OUR APPROACH
A Season-Aware Approach to Itchy Pets
Not every itchy pet has the same problem. A dog that flares up every spring is usually dealing with something different to a cat that itches all year round, and a pet with sudden hot spots needs a different response again. Our Australian-registered vets take your pet’s history, breed, and symptom pattern into account, then guide you toward the likely cause — whether that’s atopic dermatitis, flea allergy dermatitis, a food sensitivity, or a secondary skin infection — and outline sensible next steps, including treatment where clinically appropriate.

Veterinary Dermatology Terms That May Apply to Your Pet
Persistent itching may be described clinically as canine or feline atopic dermatitis, flea allergy dermatitis (FAD), contact dermatitis or a cutaneous adverse food reaction. Environmental allergens can include grass and ryegrass pollen, tree and weed pollen, house-dust mites and mould spores. The pattern matters: paw chewing and pododermatitis, recurrent otitis externa, facial rubbing, belly or groin irritation and seasonal hot spots can help narrow the likely trigger.
Allergic skin is commonly complicated by secondary Malassezia yeast dermatitis or bacterial pyoderma. Greasy skin, odour, pustules, crusting, hair loss or rapidly worsening redness may therefore need skin cytology, ear cytology, parasite testing or bacterial culture at a physical veterinary clinic rather than allergy treatment alone.
Management may include strict flea control, medicated shampoo, topical therapy and a veterinarian-supervised elimination diet trial using a hydrolysed or novel-protein diet. Depending on the diagnosis and the individual animal, a veterinarian may discuss prescription options such as oclacitinib (Apoquel) or lokivetmab (Cytopoint), while recurrent or complex cases may be referred for intradermal allergy testing or veterinary dermatology review. Treatment is individualised because these medicines are not suitable for every dog or cat.
Recurring ear inflammation often forms part of the same allergy pattern; read our pet ear infection guide for signs of otitis externa and when an ear examination is needed.
Seasonal & Skin Allergy Questions We Hear Often
Straight answers about seasonal flare-ups, fleas, food allergies, hot spots, and when scratching turns into an infection.
Why does my dog’s itching get worse in spring and summer?
Warm, humid weather increases pollen, grass and dust mite exposure, and flea numbers rise too — all common triggers for atopic and flea allergy dermatitis. An online vet can help confirm the seasonal pattern and suggest a management plan.
My dog is itching all over but I can’t find any fleas — what does that mean?
Not finding fleas doesn’t rule out flea allergy dermatitis, since a single bite can trigger intense itching. Environmental allergies and food sensitivities are also common causes worth discussing with a vet online.
What’s the difference between a food allergy and an environmental allergy in dogs?
Food allergies usually cause itching all year round, while environmental (atopic) allergies often flare up seasonally with pollen, grass or dust mites. A vet can help work out which pattern best fits your dog.
What does a hot spot on a dog look like, and how is it treated?
Hot spots (acute moist dermatitis) are red, moist, rapidly spreading patches that can appear within hours, especially in humid weather. They usually need prompt treatment to stop the itch-scratch cycle and prevent infection.
Why does my dog keep licking or chewing at their paws?
Constant paw licking is a common sign of atopic dermatitis, and can also point to a food-related allergy. A vet can help identify likely triggers and outline a treatment plan online.
Which dog breeds are more prone to atopic dermatitis?
Breeds such as Staffordshire Bull Terriers, French Bulldogs, Golden Retrievers, West Highland White Terriers and Labradors are commonly predisposed to atopic dermatitis, though any dog can be affected.
My cat is over-grooming and losing fur — could it be an allergy?
Yes. Over-grooming, hair loss and skin irritation in cats can be linked to environmental, flea or food allergies. An online vet can help assess your cat’s symptoms and discuss next steps.
Can scratching lead to a skin infection in dogs and cats?
Yes. Broken skin from persistent scratching can allow bacteria or yeast to take hold, leading to a secondary infection that often needs separate treatment from the underlying allergy.
How much does an online vet consultation for seasonal or skin allergies cost?
DocTel VetCare consultations include follow-up consultations from $49, general consultations from $79, and urgent after-hours consultations from $109, depending on the service selected. Many owners managing seasonal allergies start with a general consultation, then use lower-cost follow-ups to review flare-ups as the pollen and flea seasons change.
How quickly can I get advice about my pet’s seasonal itching?
Same-day consultations are typically available, and in many cases you can speak to a vet within hours without waiting for a clinic appointment. This is especially useful for hot spots, which can spread quickly and are far easier to manage the sooner they are assessed.
