Why Is My Dog Scratching More in Spring?

Spring in New Zealand is a beautiful time of year. The weather warms up, flowers bloom, and everything feels alive again. But if your dog suddenly can’t stop scratching, biting, or licking their skin, it can be worrying.

You’re not imagining it. Many Kiwi dogs get itchier in spring, and there are a few common reasons why.

1. Fleas Are Back in Action

When temperatures rise, flea eggs that have been lying dormant through winter start to hatch. Within weeks, you can have a full flea population in your home and garden. Even if you don’t see fleas, their bites can cause intense itching.

Some dogs are allergic to flea saliva, which makes even a single bite enough to cause days of scratching.

What to do:
Use a reliable flea preventive such as NexGard Spectra, Bravecto, or Advocate every month. Treat all pets in the household, and vacuum or wash bedding regularly to stop the flea life cycle.

2. Seasonal Allergies (Pollen and Grass)

Just like people, dogs can get hay fever too. In spring, pollen counts rise and grasses release allergens that can irritate your dog’s skin.

Common signs of spring allergies include:

• Licking paws

• Red skin or rash on the belly or armpits

• Frequent ear scratching

• Chewing or biting certain spots

What to do:
Wipe your dog’s paws after walks, wash them regularly, and keep bedding clean. If the itching continues, your vet may recommend an antihistamine or special diet to help reduce the allergic response.

3. Dry or Sensitive Skin

After the cooler months, your dog’s skin can become dry or flaky, especially if they’ve spent more time indoors with heating. Dry skin makes dogs more prone to scratching and irritation.

What to do:
Add an omega-3 supplement or feed a diet that supports skin health. Regular brushing also helps spread natural oils and keeps the coat healthy.

4. Mites or Other Parasites

Springtime is also when mites and other tiny skin parasites become more active. These can cause mange or localized itching, especially around the ears, elbows, or belly.

What to do:
Products such as Bravecto kill mites as well, giving long-lasting protection. If your dog still itches after treatment, ask your vet to check for secondary infections or allergies.

5. More Time Outdoors

Dogs naturally spend more time outside in spring. Running through long grass, rolling in the garden, or swimming in ponds can all expose them to new irritants.

What to do:
Give your dog a rinse after outdoor adventures and check for grass seeds or burrs in their coat. Keeping the coat trimmed short helps too, especially for long-haired breeds.

When to See the Vet

If your dog’s scratching causes red skin, hair loss, bleeding, or a bad smell, it’s time for a vet visit. Persistent itchiness can lead to infections or signal an underlying allergy.

Your vet can help identify the cause and recommend treatment to stop the itch for good.

The Bottom Line

If your dog is scratching more this spring, fleas and allergies are usually to blame. The best defence is prevention. Stay on top of monthly parasite control with trusted, good quality products, and keep your dog’s skin clean and healthy.
