Frequently Asked Questions
My dog is scratching so much he's bleeding – what do I do right now?
That must be awful to watch. Deep breath – first, stop the bleeding by applying gentle pressure with a clean cloth. Then get a fast-acting flea treatment on him immediately. If the bleeding doesn't stop or you see pus, call your vet right away.
How can I tell if it's flea allergy dermatitis or just normal itching?
Great question. The key clue is location – flea allergy usually hits the base of the tail and lower back. If your dog is mainly scratching those spots and has little red bumps, it's likely FAD. Normal itching is more spread out.
How long does it take for flea allergy dermatitis to go away after treatment?
It can be frustrating – most dogs start feeling better within 4-8 hours after the fleas die. But the skin may take 1-2 weeks to fully heal. Keep up with the soothing baths and prevent scratching to speed recovery.
Is it worth going to the vet or can I treat it at home?
That's a common concern. If it's a mild case (just scratching, no infection), home treatment with flea meds and shampoo can work. But if you see hot spots, oozing, or no improvement in 2 days, a vet visit is worth the cost – they can prescribe stronger anti-inflammatories and antibiotics to avoid bigger bills later.
Can flea allergy dermatitis spread to my other pets or my family?
That's scary, but the dermatitis itself isn't contagious – it's an allergy. However, fleas can jump to other pets and humans, so you need to treat all pets and the environment.
Do I need to treat my dog for fleas year-round even in cold climates?
Yes, indoor heating creates a perfect environment for fleas. Plus, wildlife can bring fleas into your yard. Year-round prevention is the easiest way to avoid those awful flare-ups.
