Fleas in dogs
Fleas are more than an itchy inconvenience—they can seriously impact your dog’s health. A single flea infestation can lead to constant biting, discomfort, and even serious medical conditions.
Fleas may cause:
- Flea Allergy Dermatitis (FAD) – a common allergic skin reaction
- Transmission of tapeworms and harmful bacteria (e.g., Rickettsiae)
- Anemia, particularly in cases of heavy infestations
Protecting your dog from fleas means protecting them from disease, irritation, and long-term health risks.
Fleas Don’t Just Target Dogs – They Bite Humans Too
Fleas aren’t selective—they’ll bite humans as well, leaving behind itchy, inflamed red spots. And once they make their way into your home, they multiply fast.
A flea infestation isn’t just uncomfortable—it’s persistent. Without quick action, it can take months to fully eliminate fleas from your living space.
Stay alert—early prevention is the key to keeping both your pet and your home flea-free.
Flea Allergy Dermatitis in dogs
Flea Allergy Dermatitis is also called Flea Bite Hypersensitivity. Some dogs are more sensitive to flea bites than others, and they can have reactions to flea saliva, causing intense itching and a rash every time they are bitten.

Look out for pink to red skin and hair loss due to scratching of self-made injury. . You may also notice small red crusts and bumps on the back and rump of your dog.
