Itching

Biting

Skin bumps and redness

Do a thorough inspection of fleas on your dog’s skin. Fleas are tiny, dark insects. If you have a black dog, you will have to take a closer look because they can camouflage.

If you are lucky, you may see the fleas in action. They may scurry away or even jump.

Flea larvae
