Dogs can get fleas from a variety of sources, including:
* Contact with other animals: Dogs can get fleas from other animals that they come into contact with, such as cats, rabbits, and wildlife. Fleas can easily jump from one animal to another.
* Infested environments: Dogs can also get fleas from infested environments, such as yards, parks, and kennels. Fleas can lay eggs in these areas, which can hatch into larvae and eventually develop into adults.
* Humans: Humans can also bring fleas into their homes and yards, where they can then infest dogs. This can happen when people come into contact with fleas outdoors or when they bring infested animals into their homes.
Fleas can cause a variety of problems for dogs, including:
* Itching and skin irritation: Fleas bites can cause itching and skin irritation, which can lead to excessive scratching and hair loss.
* Allergic reactions: Some dogs are allergic to flea saliva, which can cause severe itching, swelling, and inflammation.
* Tapeworm infection: Fleas can carry tapeworms, which can be transmitted to dogs when they ingest fleas. Tapeworms can cause a variety of symptoms, including diarrhea, weight loss, and abdominal pain.
* Anemia: In severe cases, fleas can cause anemia, a condition in which there is a deficiency of red blood cells. Anemia can cause weakness, fatigue, and pale gums.
