Recurring itching in a Shih Tzu is really common — and really frustrating, because the word 'hypoallergenic' gets slapped on so many products that it's become almost meaningless. Before you spend money on a new shampoo or food, it helps to know a bit more about what's actually going on. How long has the itching been happening, and where on the body is it worst — skin folds, paws, belly, ears? And has a vet looked at it yet, or are you still trying to figure out the cause?
It's been on and off for about six months. Mostly around her face, paws, and belly. The vet said it's likely environmental or food allergies but didn't give us much to go on. We're just trying to find something that helps without making it worse.

That pattern — face, paws, belly — is really classic for environmental allergies in Shih Tzus, though food can absolutely play a role too. The honest answer is that shampoo and food changes work best when you tackle them separately so you can see what's actually helping. On the food side, the most useful move is a proper elimination diet with a single novel protein source — something the dog has never eaten before. What is she currently eating? Knowing that tells us which proteins are still 'clean' to try.
She's been on a chicken-based dry food, a well-known supermarket brand. We haven't really changed it since we got her.

Chicken is one of the most common dietary triggers for dogs with skin sensitivities, so switching away from it is a reasonable first step. For the food, I'd steer you toward Forthglade Complete Grain Free with Turkey — turkey is a novel protein for a dog who's only ever had chicken, the ingredients list is short and clean, and it's a wet food which also keeps hydration up, which helps skin. Avoid anything with chicken, chicken meal, or mixed 'poultry' on the label during the trial — you need a clean break to see if food is a factor. Give it at least eight weeks before judging. On the shampoo side, what are you currently using to wash her, and how often?
We've just been using a generic dog shampoo every couple of weeks. Nothing special.

Generic shampoos are often fine for healthy coats, but for a dog with reactive skin they can strip the natural barrier and make things worse. For washing, I'd recommend Veterinary Formula Clinical Care Antiseptic and Antifungal Shampoo — it's widely available on Amazon UK, it's used by vets, and it contains chlorhexidine and ketoconazole which address the secondary yeast and bacterial issues that often develop on already-irritated skin. It's not a cure for the underlying allergy, but it genuinely reduces the itch cycle and keeps the skin healthier between flare-ups. Use it every one to two weeks, leave it on for five minutes before rinsing, and avoid the eye area given she's a Shih Tzu. Between those two changes — the food switch and the shampoo — you should have a much clearer picture within a couple of months of what's driving the problem.
That's really helpful, thank you. Should we be doing anything else in the meantime?

A few small things worth doing: wipe her paws with a damp cloth after walks, especially in spring and summer, because contact allergens from grass and pollen are a big trigger for this profile of dog. Keep her face folds clean and dry — moisture trapped there causes secondary skin issues fast. And an omega-3 supplement added to food (plain fish oil capsules are fine) can noticeably improve skin barrier function after four to six weeks. Nothing dramatic, but those habits together with the food and shampoo change give you the best chance of getting on top of it without needing to go back to the vet for steroids.
