From itchy paws to recurring ear infections, experts say the early signs of allergies are often mistaken for "normal dog behaviour", allowing a manageable condition to become a lifelong health challenge. With spring just around the corner, now is the time for dog owners to prepare for allergy season. Recognising the early signs may help prevent more serious, and potentially more expensive, health problems.
Canine atopic dermatitis, commonly known as environmental allergies, is recognised as one of the most common chronic inflammatory skin diseases in dogs, affecting an estimated 15% of the canine population. The condition is characterised by persistent itching, inflammation and skin barrier dysfunction, with many dogs also developing secondary ear and skin infections if left unmanaged.
Spring pollen, grasses, weeds and environmental allergens often trigger flare-ups in dogs already predisposed to allergies, making late winter and early spring an ideal time for owners to monitor their dog's skin more closely.
"Allergies often begin with subtle, intermittent signs rather than severe symptoms. Many owners assume occasional scratching, paw licking or recurrent ear irritation is simply part of being a dog. But when these behaviours become persistent or repeatedly return, they're often an early indication that the skin barrier or immune system needs attention. Recognising these signs early gives owners the best opportunity to seek veterinary advice before the condition progresses.”
According to veterinary dermatology experts, allergies rarely begin with severe symptoms. Instead, dogs often show subtle changes that gradually worsen over time.
Early warning signs owners shouldn't ignore
- Persistent scratching
- Licking or chewing paws
- Recurring ear infections
- Red or inflamed skin
- Hot spots
- Hair loss
- Rubbing their face on furniture or the ground
- Recurrent skin or yeast infections
The International Committee on Allergic Diseases of Animals (ICADA) describes canine atopic dermatitis as a complex condition involving an interaction between genetics, the immune system, the skin barrier and the skin microbiome. Modern management focuses on identifying the underlying cause while supporting skin health and reducing inflammation over the long term.
“Nutrition plays an important supporting role in maintaining healthy skin and a resilient skin barrier. A complete and balanced diet that provides quality protein, essential fatty acids and key nutrients helps support normal skin function, while ingredients that nourish the gut microbiome, including prebiotics, probiotics and postbiotics, may also help support overall immune health,” Rachael recommends. “Nutrition should always complement veterinary diagnosis and treatment, not replace it.”
While allergies cannot always be prevented, experts say recognising symptoms early and working closely with a veterinarian can help reduce flare-ups, improve quality of life and minimise secondary infections.
The financial impact can also be significant once skin disease becomes chronic.
According to Australian pet health data from PetSure, the average cost to treat allergic skin disease ranges from $300-$700, with the highest individual pet insurance claim recorded at a whopping $21,209.
Experts agree that any dog can develop allergies. However, veterinary research shows some breeds are genetically more predisposed than others, including French Bulldogs, Labrador Retrievers, Golden Retrievers, German Shepherds, Boxers, West Highland White Terriers, Bull Terriers, Shar-Peis, Bulldogs and Pugs. With many of these breeds popular in Australia, it is no surprise that the prevalence of allergies within our dog community is high.
“Chronic itching isn't just uncomfortable—it can damage the skin barrier, increase the risk of secondary infections and become much harder to manage over time. Seeking veterinary advice early is often kinder on the dog, may reduce long-term treatment requirements, and can potentially help owners avoid more significant veterinary costs."
