Fleas in Dogs

Fleas are annoying for you and your dog. Flea bites cause itching and inflammation, and fleas can carry diseases. In addition to being itchy, a flea infestation can make your doggy sick if left untreated.

Poor nutrition

Poor nutrition can lead to anemia and skin problems. Fleas cause significant blood loss by causing a dog’s immune system to react, which causes the dog to have a lower concentration of red blood cells in its body. This leads to anemia, a condition where red blood cells are not being produced fast enough for the body’s needs. Fleas also cause skin rashes and allergies by irritating your dog’s skin with their saliva and feces, leading your pet’s immune system to attack them as if they were bacteria or viruses.

Poor nutrition can also make dogs more susceptible to flea infestations because they become weaker overall and are less likely able to fight off an infection like this one

Flea allergy dermatitis

If a dog has flea allergy dermatitis, it will experience symptoms such as hair loss and red skin. The itching that follows can cause the animal to scratch and chew at the affected area until it becomes raw. Fleas are not necessary for the development of this condition, but they are one of its most common causes.

Flea allergy dermatitis is not contagious.

Anemia

Fleas can cause anemia by ingesting the dog’s blood. They also cause blood loss when you scratch at a flea bite and the skin breaks (this is called a “flea allergy dermatitis”).

  • In puppies, cats, and kittens: When a flea bites them, it sucks up their blood. Over time this can weaken their immune systems and even lead to anemia. This isn’t as common in adult dogs but it can still happen.
  • If you have a pregnant dog: Fleas will suck on her unborn puppies too—and if they take enough blood they may be born underweight or with low red cell counts that make them more susceptible to infections later in life. This condition is called congenital parasitism (parasites are things like worms).
  • If you have an elderly dog who suffers from kidney disease or other health problems: These dogs might not produce enough red cells themselves so having them sucked out by parasites will make things worse.

Tapeworms

Tapeworms are parasites that live in the digestive tract of animals. They are transmitted by fleas or through a bite from an infected fleas. Tapeworm larvae can be eaten by cats and dogs, which can pass them into their feces. The tapeworm eggs are then picked up by fleas, which then become infected with the tapeworms. A dog or cat may become infected when it eats an egg-carrying flea during grooming or cleaning itself after it has been outside playing in areas where there are many other animals that have been infected with tapeworms in the past year.

Tapeworms can cause anemia and weight loss if they grow too large because they will feed on nutrients from your pet’s internal organs instead of using those nutrients to build muscle mass like normal pets do! Luckily for us humans though, these parasites do not cause any issues for us at all – but we should still keep our pets safe from getting them so they don’t go crazy eating everything we own!

Hair loss

Fleas can cause hair loss.

Fleas are parasites, and like most parasites, they feed on the host animal. They do this by sucking blood from the animal’s skin. This can make your dog anemic (low on red blood cells) which can lead to other health problems such as weakness and fatigue. Also, many dogs are allergic to flea saliva or flea eggs (flea bites). If your dog’s immune system is compromised due to another disease (for example: cancer), parasites may be more likely to attack his/her body because their immune systems aren’t working well enough to fight them off with ease.

Conclusion

If your dog has fleas, you need to eliminate them. Their bite can cause serious health problems, including anemia. Additionally, if your dog is infested with fleas and they end up in your home or yard it can lead to a long term flea problem in both areas.
