Why Do We Need to Keep Away Fleas?
To explain to you how serious this issue is, you should know that there are more than 2,200 species of fleas around the world. They are not just some itchy nuisance, they transmit many diseases that thrive in your dog’s blood.
Fleas are attracted to dogs because they are warm-blooded animals, and this is the perfect environment for them. Also, they sneak into the dog’s fur and hide there. But their philosophy does not stop here.
These tiny creatures also have a favorite hiding spot on your dog. This is a place they choose, and there they can feed themselves and reproduce. The most common areas include the following:
- Neck and ears
- Base of the tail
- Between toes
- Around the belly and the inner thighs
In these places, they reproduce rapidly and lay up to 50 eggs per day. These eggs fall off the dog, onto the bedding, carpets, furniture, etc. They hatch in a period of 1 to 6 days, and then comes the larvae which hide in dark places.
Fleas prefer warm and humid conditions to survive. Then, fleas develop in stages and start “attacking” your dog. The worst thing is that an infested dog can “introduce new fleas” into the home. These fleas can even be a threat to you as an owner or to other pets in the same household.
If you notice your dog is fighting with these “little demons,” react immediately. If you leave them and ignore this issue, you will have a dog that is constantly itching and in discomfort.
And the problems don’t stop here. They can even get a serious infection or allergy. The most common is flea allergy dermatitis. This is a severe reaction due to flea saliva that results in inflamed, red, and infected skin.
Even if there is no infection, the constant itching could lead to hairless patches on your dog’s skin that are prone to serious threats from the environment.
Puppies and senior dogs are sensitive dog categories, and they are at a high risk of anemia that can cause weakness or fatigue. Worst case scenario, if a dog ingests a flea carrying tapeworm larvae, they can develop an intestinal parasite. Other common diseases due to fleas are:
By ignoring it, you will only put yourself at a high risk of flea infestation in your home.
So, if you are into alternative medicine, you will probably think about the natural solution. And the first thing you might think of is apple cider vinegar.
Can Apple Cider Vinegar Kill Fleas?
Apple cider vinegar is a common ingredient in cooking, but many people don’t realize it has a variety of other uses beyond the kitchen. I personally used it while I was trying to lose weight, but I’ve heard that this kitchen ingredient also has other purposes. It has a strong smell, and its acidity makes it an effective flea repellent.
The harsh truth is that this ingredient DOES NOT kill fleas; it only repels them. Fleas just don’t like the smell and taste of it, and if your pet has it, they will avoid it.
But this is not the only problem. When you apply ACV to your pet, it can cause them discomfort because of the stickiness.
So, if you thought of using apple cider vinegar for fleas while your dog is having a serious infestation, it won’t help them. In these cases, proven treatment solutions are the best idea.
Side Effects of ACV
The first problem when applying ACV to your dog is that there is no scientific proof that this remedy is safe and efficient. There are some possible side effects of it, including:
- Skin irritation - Some breeds might be more allergic than others. If your pet had some previous allergies in the past, be careful what you offer them.
- Stomach upset - This might sound unrealistic, but the truth is that pets are curious and will try to lick “the thing” that you applied. If they lick too much and are sensitive, they can develop a stomachache.
- Eye and nose sensitivity - Do you know that dogs have around 300 million olfactory receptors in their noses, compared to about 5 to 6 million in humans? Well, do you understand now how sensitive they can be to this smell. Try preparing a salad with apple cider vinegar, and if you put a bit too much, you will notice a weird feeling inside your nose. Well, imagine what happens to dogs when they smell this.
If your decision to use ACV is strong, then you should apply it to a small area of skin. Then, wait to see if your dog gets any skin irritation. But even if it doesn’t have any negative consequences in this “trial” period, no one guarantees that your dog won’t experience any side effects.
Disclaimer: There is a trend toward natural remedies, and almost 55% of pet owners are highly receptive to the idea of giving to their pets. But you should always consult with a veterinarian before you give your dog any new alternative medicines.
