Well, let's begin with feeding wholesome homemade food. This will help minimize the toxins that enter your pet's body and maximize the the toxins that leave. This in turn helps create normal and healthy skin. Immediately this helps to create the environment of a healthy animal, not a dead one. Fleas don't like this and begin looking for a new toxic environment.
Now don't expect wholesome homemade food to get rid of every flea and don't expect it to work over night. There are many factors that get involved in determining whether or not there will be a flea problem including, but not limited to, the area in which you live, the climate, time of year and so on.
The good news is that people who feed wholesome homemade food tend to experience fewer fleas and sometimes no fleas as their companions begin their journey on the road of health. The reality is, a flea or two is not a problem. Fleas naturally exist. But a flea infestation, now that's a problem. A flea infestation indicates an unhealthy body but as your pet gets healthier while eating a wholesome homemade diet, then the flea infestation naturally begins to go away.
If you have ever read books like Dr. Pitcairn's Complete Guide to Natural Health for Dogs and Cats you will notice that for skin problems like fleas, ringworm, mange, ticks to name a few, it is suggested that people should ensure their companion is getting enough of the mineral called sulphur. Sulphur helps with skin problems.
Garlic is said to repel fleas, and it does, but not because of its odour. It does so because it has a high sulphur content. Equally important to ensuring that your companion gets enough sulphur, one needs to ensure your companion can utilize the sulphur. You can be feeding foods high in sulphur, but if your pets can't utilize the sulphur, then the sulphur is useless. The best way, in my opinion, to ensure your companion is utilizing nutrients of all kinds is to feed wholesome, natural foods with good supplements — the key word again is balance.
It's worth noting that it is reported that garlic is said to be toxic to pets in larger doses. This is true of any vegetable that is a member of the onion family. As a result, I personally do not use garlic in my pet's diet. Even though garlic may be safe in lower doses, I simply prefer to not take the chance.
Okay, so you've minimized the toxins entering the body by eliminating chemicals, you're feeding wholesome homemade food, sulphur is coming into the body naturally, so — what else can be done?
Well, in addition to minimizing the toxins entering the body, we can help maximize the toxins leaving by introducing some herbs or nutritional supplements that aid the body in detoxifying. Even if your pet doesn't have fleas, it's always a good idea to help purify the blood, aid the kidneys, liver and lymphatic system.
Obviously, constantly washing the bedding and vacuuming your carpets is another good idea that helps with flea problems.
From a herbal standpoint, a good herbal shampoo can be used to help wash off any toxins and clean the skin. I personally do not use shampoos that contain artificial ingredients like propylene glycol.
I also prefer to stay away from products that contain herbs like cedarwood, pennyroyal, citronella, eucalyptus, and tea tree oil.
It is true that many use these herbs, but we must remember that our pets have a sense of smell 1000 times more powerful than ours. Since the above mentioned herbs are strong smelling, they will give your pets a nauseous feeling, migraines and more.
These products may be suitable for humans, but they should be kept away from dogs and cats. If you don't believe me, put some tea tree oil under your dog or cat's nose and watch them turn away!
In addition, these products can irritate the skin and we must always remember that any product that goes onto the skin of our pets should be safe to be licked internally. For example, even if pennyroyal had a soft aroma, we still must remember that this herb is lethal and has been used to induce abortions. Pennyroyal should only be used while under the direct supervision of a master herbalist. It is reported that only 50mg/kg of pennyroyal oil can be lethal.
These products sell quite well because just like with commercial pet foods, it is the human that is buying these products and not the pets. Our pets don't have a choice. They rely on you.
