Why is my dog itching with no fleas, even on flea prevention?

Updated On September 23rd, 2025

Pet's info: Dog | American Cocker Spaniel | Female | spayed | 1 year and 4 months old | 13 lbs

Sophie has Bravecto. She is due for another chew in 2 weeks. She is itching though. Can she have the Bravecto early? Or can I put a dose of Revolution on her until she gets Bravecto again. I do NOT see any fleas on her at all. Bathed her. She is biting the tops of her paws. She has that itch reflex when I run my fingers up her spine. No sign of of skin redness, scaling or irritation.

Bravecto is generally a very good product and at this point, especially with not seeing any fleas, it’s unlikely that they are the cause of itching. I don’t recommend to apply another product or to give the Bravecto early. Pets can be itchy for many reasons. Itching on the feet can be a sign that she walked through a chemical or plant that may be causing an allergic reaction. Also try to recall if she has had any new foods or treats as that could cause itching too. Lastly, environmental allergies can flare up when our homes are closed up in winter time with the furnace circulating large amounts of dust, dust mites and other indoor allergens. At home you can start her on an omega 3 fatty acid supplement for dogs, this will help improve skin health. You should also call you veterinarian and ask about antihistamines or if they think she needs something stronger. Bathing her in a oatmeal dog shampoo and conditioner can also help decrease itchiness. Most dogs can be bathed once a week. I hope this is helpful and please feel free to post any additional questions.
