Shopping for dogs with sensitive skin

Persistent itching has a long list of causes and most of them are not solved by shopping. Parasites, allergies, hormonal conditions and infections all present as a scratching dog, and the products below help around the edges of a diagnosis rather than instead of one.

Order of operations

• Rule out parasites with your vet. Flea allergy is still the single most common cause of itching and it takes very few fleas.
• Get a diagnosis before an elimination diet. Running one badly wastes eight weeks and tells you nothing.
• Only then start changing food, grooming and bedding, one variable at a time, three weeks apart.

Food

If your vet does want a food trial, a single named animal protein and a short ingredient list is the point, not the word "hypoallergenic" on the front. Read the composition panel: a recipe listing three meats and "meat derivatives" cannot be part of a controlled trial no matter what the marketing says.

Grooming

Use a rounded-pin brush on a flexible cushion rather than a stiff slicker. The aim is to lift loose hair and spread skin oils without dragging on inflamed skin. Bathe only as often as your vet advises. Over-washing strips the coat and makes the underlying problem worse, and a medicated shampoo needs its full contact time to do anything at all.

Bedding and laundry

• Choose a bed with a fully removable cover that survives a 60°C wash, which is the temperature that matters for dust mites.
• Wash bedding weekly during a flare, fortnightly otherwise.
• Use a non-biological, fragrance-free detergent and skip fabric softener entirely.
• Keep a spare cover so the bed is never out of service. A dog that has to sleep on the floor during laundry day just finds a rug instead.

Change one thing, wait three weeks, write it down. Otherwise you will never know what worked.

Keep a short log with the date, what changed and a one-to-five itch score. It looks fussy and it is the single most useful thing you can bring to a follow-up appointment.
