After a run of wet weather, you might notice your dog scratching, chewing at their coat or struggling to settle. The weather may have you wondering about fleas. It is worth checking, but scratching alone cannot tell us what is wrong.
If your dog is uncomfortable, getting to the cause comes first. Repeated scratching or licking needs attention rather than being dismissed as a new habit.
Can rainy, humid weather mean more fleas?
Flea development is influenced by temperature and moisture. Warm, humid conditions can help their immature stages survive in suitable environments. That makes prevention worth keeping on top of in Brisbane, rather than waiting until your dog starts scratching.
Rain itself doesn’t prove there is a flea problem. Conditions around bedding, sheltered resting areas and inside the home also matter. Fleas can remain a concern beyond the hottest part of the year.
Look beyond the fleas you can see
Adult fleas live on animals, while eggs and other developing stages can be present in the surroundings. This helps explain why dealing with a problem may involve both your pet and their environment.
Regularly wash bedding according to its care instructions and vacuum places where pets rest. If fleas have been found, ask your vet for a plan that covers the animals in your household and their shared spaces. Seeing more fleas after treatment doesn’t automatically mean the product has failed, as environmental stages may still be emerging.
Choose prevention for your own pet
Your vet can help select a product suited to your dog’s age, weight, health and local risks. Follow the label, keep to its schedule and check any bathing or swimming instructions.
Don’t double up products or give extra doses because your dog is still itchy. If you have cats or other animals, check that every product is appropriate for the animal receiving it.
Scratching doesn’t always mean fleas
Allergies, mites, infections and other skin problems can also cause licking or scratching. Flea allergy can make bites particularly uncomfortable, and more than one problem can be present at the same time.
Look for redness, sores, hair loss or repeated attention to one area. Paw licking alone cannot tell you whether the cause is fleas, an allergy or something else. Arrange a veterinary check if the behaviour persists, the skin is damaged or your dog seems uncomfortable.
Think about comfort before behaviour
If your usually settled dog becomes restless or irritable, consider whether something physical has changed. A training exercise won’t resolve an untreated skin problem.
Keep a brief note of when the scratching started, where your dog is licking and which parasite products have been used. That information can help your vet work out what is happening.

Does an itchy dog after rain definitely have fleas?
No. Fleas are one possibility. Allergies, irritation and infections can look similar, so persistent itching needs a veterinary assessment.
Should I give another flea treatment if the scratching continues?
Check with your vet first. Tell them which product you used and when. Another dose may be inappropriate, and the scratching may have a different cause.
