Flea Allergy Dermatitis in NZ Dogs: Calm the Itch Fast
What is flea allergy dermatitis
Some dogs are allergic to flea saliva. One bite can trigger days of intense itch, often over the rump and tail base. You may see red skin, scabs, hair loss, or constant scratching. The fix is a steady plan that stops new bites and soothes the skin.
Your 5-step relief plan
-
Start reliable flea control today
Pick an application you can give on time, every time. For dogs, proven options include:
-
Treat every pet in the home
Untreated pets keep the life cycle going. Dose all dogs and cats on the same day to avoid bounce-back. -
Clean the environment
Hot-wash bedding. Vacuum rugs, skirting boards, sofas, and car seats. Empty the vacuum outside. Repeat weekly for a month. -
Soothe the skin
Use a gentle, vet-recommended shampoo and cool water. Avoid harsh products. If skin is broken, smelly, or very red, book a vet visit. -
Stay consistent for 3 months
Flea eggs in the home can hatch for weeks. Keep prevention on schedule. Set phone reminders so dates are not missed.

FAQ
Can one flea bite really cause all this scratching
Yes. Dogs with flea bite allergy can react to a single bite, so strict, on-time prevention is key.
How long until my dog is comfortable
Many dogs improve within a few days once new bites stop. Skin often takes one to two weeks to fully settle. Keep going even if you cannot see fleas.
Do I need to treat my indoor cat too
Yes. Fleas can thrive in warm homes. Treat all pets to stop the cycle.
Chew or spot-on. Which should I pick
Choose the option you can give on time. Chews suit swimmers and hands-off homes. Spot-ons suit owners who prefer a quick skin application.
