Seasonal, environmental itching

What this tends to look like

• Worse at particular times of year, or worse after time outdoors
• Focused on paws (licking and chewing), face, ears, belly and armpits
• Skin often looks close to normal between flare-ups
• No fleas, and prevention is up to date
• Often starts in the first few years of life and repeats each year

What is usually going on

A pattern like this, tied to the seasons and concentrated on the thinly-haired parts of the body an animal presses against the ground, is the classic picture of reaction to something inhaled or contacted in the environment: pollens, grasses, molds, dust mites. It is one of the most common reasons dogs and cats itch, and it is a management problem rather than a curable one. The realistic goal is fewer and milder flare-ups, not a permanent fix.

What you can do at home

• Rinse or wipe the paws and belly after walks, which physically removes pollen rather than waiting for it to be absorbed
• Bathe with a plain colloidal-oatmeal shampoo, lukewarm not hot, and let it sit on the skin a few minutes before rinsing
• Keep a simple diary of flare dates. A year of dates is genuinely useful diagnostic information for a vet
• Wash bedding weekly in hot water during flare season
• Give omega-3 a fair trial. Any coat and skin benefit builds over six to eight weeks, so judging it after a week tells you nothing

When to stop and call your vet

• The skin becomes broken, crusted, smelly or greasy, which suggests a secondary infection that supplements will not touch
• Recurrent ear infections alongside the itching
• The itch stops responding to what used to help
• Flare-ups are now most of the year rather than one season
