Keeping your pet’s health at the highest level is a true challenge, and protecting your dog from fleas can feel like a never-ending battle. Owners start to feel this during the warmer months.
Even if you are trying to prevent an infestation or you are dealing with one, finding the right solution is pretty hard. There are many flea treatments available, and each has promising results, but often you might get confused and wonder what actually is the best solution is for your dog.
So, today, we are going to discuss the natural remedies and how they work against fleas. Let’s discuss how does lemon juice work against fleas and what the most effective methods are to keep your dog safe and sound!
Why Do We Need to Keep Away Fleas?
Fleas are extremely serious, as there are more than 2,200 species of fleas around the world. Besides causing itchiness, they can transmit many serious diseases that thrive in a dog’s blood.
Dogs are the perfect hosts for fleas because they offer everything that fleas need to survive, including:
- Warmth
- Moisture
- Shelter (fur)
Once fleas sense that they have a dog in their surrounding, they quickly attach because this is their way to feed themselves.
Fleas have strong back legs that allow them to jump and land on a dog. They use their sharp, clawed feet to catch tightly in between the fur. Sucking the dog’s blood allows them to survive and reproduce.
The most common areas where they attack include the following:
- Neck and ears
- Base of the tail
- Between toes
- Around the belly and the inner thighs
If you don’t do anything about fleas, then the situation can escalate quickly, and here is what to expect:
- Constant itching and scratching
- Flea allergy dermatitis
- Anemia
- Tapeworm infections
- Flea infestations inside the home
By ignoring fleas, you will only put yourself at a high risk of flea infestation in your home. But also, you will put the other pets in your household at risk.
Can Lemon Juice Kill Fleas?
You might wonder why do these solutions become popular? Well, it is pretty simple, it is a simple and cheap option. The recipes are various, and the most common that people use is one whole lemon combined with 1 cup of water.
You can use this water to comb your dog. But the problem is that this is not the final solution, as lemon juice can only deter or repel the fleas, and not kill them.
What Other Uses Does Lemon Juice Have?
Dogs in general should not eat lemons because it is highly toxic. Lemon juice has only a few minor uses in dogs, and you should be very cautious because lemon is acidic and can cause irritation if used improperly.
When applied topically, lemon juice can neutralize mild odors on the dog’s coat. So when you apply lemon juice to deter fleas, you will also have a good-smelling dog.
Side Effects of Lemon Juice
When used as advised, lemon juice should not be harmful for your dog. However, if used improperly, it can cause some unwanted side effects:
- Skin irritation
- Upset stomach
- Eye irritation
- Allergic reactions
- Toxicity
If you decide to topically add lemon juice to your dog, then use it with caution. Add lemon juice to a small area and monitor your dog closely. If your dog shows some unwanted effects, then stop adding it to larger areas.
