You hear it before you see it. The thump of a back leg against the floorboards at two in the morning. The wet, rhythmic sound of a dog working at his own paws. The face rubbed along the couch, the carpet, your leg, anything with a bit of grip. Spring arrives in South Africa and, for a lot of dogs, so does the itch.
Vets will tell you the scratching dog is one of the most common things they see from September onwards. Pollen is usually blamed, and often that is fair. But the itch has three main causes, they look almost identical from the outside, and the fix for one does nothing for the others. This is a guide to working out which one you are dealing with, and what a limited-ingredient food like Acana Singles can and cannot do about it.
Why Spring Is Itch Season in South Africa
Dogs do not get hay fever the way we do. They rarely sneeze or get a runny nose. When a sensitive dog breathes in or walks through an allergen, the reaction shows up in the skin instead: the paws, the belly, the armpits, the ears. Vets call it atopic dermatitis. Owners call it "he will not stop licking".
Our spring makes this worse than most. Gauteng gets the jacarandas and the plane trees. The Western Cape gets oaks, pines and a fynbos bloom that goes on for months. Everyone gets kikuyu grass, which is in nearly every garden and park in the country and is one of the most common triggers we hear about. Add a mild winter that never fully cleared last season's pollen, and some dogs are itchy for nine months of the year rather than three.
The same warm weather wakes up fleas and ticks, which brings us to the first thing to rule out.
The Three Culprits
1. Parasites
A single flea bite can keep a flea-allergic dog scratching for a week, and you will not necessarily find the flea. If your dog is not on a reliable tick and flea product all year round, start there before you change anything else. It is the cheapest test you will run. Our pest control range covers chewables, spot-ons and collars. Mites and skin infections cause similar itching too, which is why a vet visit is worth it if the skin is red, raw, smelly or losing hair.
2. Environmental allergies
Pollen, grass, dust mites, mould. This is the big one. The tell is the pattern: the itch arrives with a season and eases when it passes, and it concentrates on the bits that touch the ground and the air, so paws, belly, groin and armpits. Recurring ear infections and reddish-brown staining on the fur between the toes from constant licking are classic signs.
Food will not cure an environmental allergy. Nothing you put in the bowl stops kikuyu pollen landing on a paw. What good nutrition can do is strengthen the skin barrier, which is why omega-3 fatty acids keep coming up in vet advice for itchy dogs. More on that below.
3. Food sensitivity
This is the one most owners jump to first, and it is less common than the other two. But it is real, and it is the only cause you can actually eliminate rather than just manage. The tells are different: a food-sensitive dog tends to itch all year, not just in spring. Ears and the back end are often involved. And there is frequently a gut clue alongside the skin, such as soft stools, extra gas or the occasional vomit.
The trigger is almost always a protein the dog has eaten for a long time. In South Africa that usually means chicken or beef, because they are in nearly everything. Grain does show up in the allergy studies, but well behind the meats, and far less often than the packaging implies.
How to Actually Test for a Food Sensitivity
There is no reliable blood or saliva test for food allergies in dogs. The only method vets trust is an elimination diet: feed one food, built on one protein the dog has never eaten, for eight to twelve weeks, and feed nothing else. If the itch settles, you have your answer. If it does not, food was not the problem and you can stop guessing.
Most attempts fail on the "nothing else" part. The trial ends the moment the dog gets a dental chew, a bit of biltong, a peanut butter Kong, a lick of the cat's bowl or a flavoured tablet. Eight weeks of discipline is what it costs to know for certain.
The food you use matters just as much. It needs to be a genuinely limited-ingredient diet, with a single animal protein and a short list of everything else. That is exactly what Acana Singles was built for, and why it is the range we reach for when a customer describes an itchy dog with a suspect gut.
What Makes Acana Singles Different
Most premium dog foods are a mix of proteins. Chicken, turkey, fish and eggs in the same bag, which is great nutrition for a dog with no sensitivities and a nightmare if you are trying to work out which ingredient is the problem. Acana Singles goes the other way. One animal protein, and half the recipe is made of it.
Take the Grass-Fed Lamb recipe. It is 50% lamb ingredients, and lamb is the only animal in the bag: raw lamb, lamb meal, and then lamb liver, tripe and kidney in the WholePrey ratios Acana uses across its range. The rest is whole peas, lentils and chickpeas in place of grain, fresh apples, butternut and pumpkin for gentle fibre, and omega-3 from algae rather than from fish, so there is no second animal protein sneaking in through the oil. No grain, no potato, no plant protein concentrates. It runs at 31% protein and 15% fat, and it is rated for all life stages.
Three recipes, three different proteins, all built the same way:
- Grass-Fed Lamb: New Zealand ranch-raised lamb. The one we recommend most often for itchy dogs, unless the dog has been on a lamb food before.
- Yorkshire Pork: pork is uncommon in dog food compared with chicken, beef and lamb, which makes it a novel protein for most dogs and a strong pick for an elimination trial.
- Free-Run Duck: a third novel-protein option, useful if the dog has already been on lamb or pork.
Two honest caveats. Singles is a premium food and it is priced like one. And it is not a magic cure: if your dog's problem is pollen, a single-protein diet will improve the coat and possibly take the edge off the itch through the omega-3s, but it will not make the pollen go away. Read the section above before spending the money.
Running the Trial Properly
If you have decided to test food, here is how to do it so the result actually means something.
- Switch over ten days. Acana Singles is rich, and a sudden swap will give you loose stools that muddy the picture. 25% new for three days, then 50%, then 75%, then fully across.
- Feed only the trial food for eight weeks. No treats, chews, table scraps, dental sticks or flavoured supplements. If you need a training reward, use a few kibbles from the bag.
- Ask your vet about medication. Some tick and flea chewables and some tablets are flavoured with animal protein. Your vet can tell you which are safe during a trial.
- Keep a simple diary. A scratch score out of ten each evening, plus a note on stools. Memory is unreliable and the improvement is gradual.
- Reintroduce the old food at the end. This is the step everyone skips. If the itch comes back within two weeks of going back to the old food, you have confirmed it. If it does not, the improvement was probably the season changing, not the diet.
Skin takes time. Gut changes show within a fortnight, but coat and itch take six to eight weeks because the hair cycle is slow and inflamed skin settles gradually. Do not judge at week three.
Things That Help Whatever the Cause
While you work out what is going on, these make life more comfortable for the dog and do no harm.
- Rinse the paws after walks. A bucket of water at the back door, or a damp cloth over the paws, belly and legs, removes a surprising amount of pollen before the dog licks it off. This is the single most useful habit for a pollen-sensitive dog.
- Wash the bedding weekly. Hot wash. Dust mites and pollen collect in the bed and the dog lies in it for twelve hours a day.
- Walk at midday rather than early morning. Pollen counts are highest first thing and on windy days.
- Get omega-3 into the diet. EPA and DHA support the skin barrier from the inside. Acana Singles carries it from algae. Otherwise, a fish oil supplement from our itchy dog range does the same job.
- Keep flea control going all year. Cape Town and Durban do not get cold enough to kill fleas off. One missed month in July is why the dog is scratching in September.
- Go to the vet if the skin is broken. Red, weeping, crusty or smelly skin means a secondary infection has set in, and no diet or paw rinse will fix that. Medicated shampoos and a short course of treatment will, and the dog will thank you.
FAQs
Is my dog's itching caused by food or allergies?
Environmental allergies are the most common cause of itching in South African dogs, food sensitivity is less common, and parasites need ruling out before either. Seasonal itching on the paws and belly points to pollen or grass. Year-round itching with ear problems and an unreliable stomach points to food. An eight-week elimination diet on a single-protein food is the only reliable way to confirm a food cause.
Does grain-free dog food help with itching?
Not on its own. Grain is an uncommon trigger in dogs. The proteins are usually the problem, particularly chicken and beef. Acana Singles happens to be grain-free, but the reason it works for sensitive dogs is the single animal protein and the short ingredient list, not the absence of grain.
How long before a limited-ingredient diet makes a difference?
Give it eight to twelve weeks before deciding. Stool quality improves first, usually within two weeks. Skin and coat are slower because hair grows out over weeks and inflamed skin takes time to settle.
Can I feed Acana Singles to a dog that is not sensitive?
Yes. It is a complete and balanced food for all life stages, and plenty of customers feed it simply because their dog does well on it. The one exception is puppies expected to weigh more than 32kg as adults, who need a large-breed puppy formula.
Which Acana Singles recipe is best for allergies?
Whichever protein your dog has not eaten before. For most South African dogs that have grown up on chicken-based foods, all three qualify. Pork is uncommon in dog food and often the safest bet for a strict trial. If you want the full picture on food allergies, we wrote a separate guide on hypoallergenic dog food.
