Understanding Fleas and Their Harmful Impact on Dogs
What Are Fleas and How Do They Affect Dogs?
Fleas are tiny, wingless parasites that feed on the blood of mammals, including dogs. Their bite leads to severe itching, skin irritation, and, in some cases, serious health complications. Beyond causing discomfort, fleas can transmit diseases, leaving your dog vulnerable to more than just an itch.
Common Health Problems Caused by Fleas
- Skin Irritation: Flea bites cause persistent scratching, leading to hair loss, open sores, and even infections.
- Allergic Reactions (Flea Allergy Dermatitis – FAD): Some dogs develop allergies to flea saliva, triggering severe itching and inflamed skin.
- Anemia: In severe infestations, blood loss can lead to anemia, making your dog lethargic and weak.
- Disease Transmission: Fleas carry parasites and diseases such as tapeworms, Bartonella (cat scratch fever), and murine typhus.
- Behavioral Issues: Chronic infestations can cause restlessness, anxiety, and mood changes due to constant discomfort.
A proactive flea control plan, including flea collars, is essential to safeguard your dog’s health and comfort.
