1. **Flea Allergy Dermatitis (FAD)**: Many dogs develop an allergic reaction to flea saliva, leading to intense itching, redness, and inflammation of the skin. This condition can result in secondary infections due to constant scratching and biting at the affected areas.
2. **Anemia**: In severe infestations, fleas can consume a significant amount of blood, leading to anemia, especially in puppies and small breeds. Symptoms of anemia include lethargy, weakness, and pale gums.
3. **Tapeworms**: Fleas can carry tapeworm larvae. If a dog ingests a flea while grooming, it may become infected with tapeworms, which can lead to digestive issues, weight loss, and discomfort.
4. **Dermatitis and Skin Infections**: Flea bites can lead to dermatitis, and the constant scratching can create open wounds, which can become infected. This can cause further complications and require veterinary treatment.
5. **Transmission of Diseases**: Fleas can transmit various diseases to dogs, including Bartonella (which can cause cat scratch fever) and even some forms of the plague in rare cases. While these are less common, they are still potential risks associated with flea infestations.
6. **Behavioral Changes**: The discomfort caused by fleas can lead to changes in behavior, such as increased irritability, restlessness, and changes in eating or sleeping habits.
To prevent these health risks, it's essential to maintain a regular flea prevention regimen, including topical treatments, oral medications, and regular cleaning of your dog's environment. Regular vet check-ups can also help monitor for any flea-related issues.
