As every dog and cat is different, results will vary based on a number of factors including environment, severity of the condition, age, genetics and more. Many dogs and cats with flea sensitivities have benefited from the addition of NuVet Plus® to their diet.


Fleas cause our canine and feline friends many problems. Pets may not always feel the initial bite, however they do suffer the aftermath. Some dogs and cats develop an allergic reaction to an antigen in the flea saliva. This allergic reaction will cause them to itch and scratch the bite location, resulting in development of an infection. Moreover, this allergic reaction known as flea bite hypersensitivity or flea allergy dermatitis is classified as a seasonal allergy, which occurs most often during spring and fall, when flea infestations are at their highest. It develops in pets with allergies to one or more of the foreign proteins that attach to flea saliva bacteria (antigens).


Characteristic found in dogs or cats with fleas include, biting, scratching as well as, rubbing itself against corners of chairs or doorways to relieve the itching sensation caused by the flea bite. Usually, a pet will bite at the flea until the flea dies, and the itching subsides. Pets that experience an allergic reaction will excessive itching, scratching and biting at the spot.


If left untreated, excessive itching cases (pruritus) can lead to hot spots: raw, red spots on skin and fur that usually appear behind the ears, in ear flaps and on legs, flanks, feet and the rear end. Hot spots (superficial pyoderma) inflame and become infected from the constant irritation; pus from infected sites enters the intestinal tract when the affected dog or cat bites and licks at the wound. From there, the infection can readily spread to the rest of the body. All this from a single flea bite!

NuVet Plus

A healthy skin and coat and strong immune system provide an essential defense against flea infestations and bites and help to prevent flea bite hypersensitivity from developing in sensitive dogs. When bites do occur, good skin and coat health helps wounds heal quickly to prevent hot spots and infections.

NuVet Plus also helps boost their immune system so that the body can fight off infections.

Supporting your pet’s diet with a high quality food containing essential protein will add critical nutrients to their bodies.  Equally important is providing food, that is low on grains like corn and wheat as well as “meat by-products”. However, even a high quality pet food alone isn’t enough.  NuVet supplements are a vital component, helping fill the nutritional gaps to keep your dog or cat healthy.   It boosts internal defenses and provides critical nutrients to the blood, bones, and skin as well as supporting the vital organs to help prevent the damaging effects of free radicals.

NuVet®’s Hot Spot Treatment Spray offers immediate relief from the agony of hot spots. It contains natural eucalyptus extract and aloe vera to comfort and heal hot spots, flea bites and flea allergy dermatitis.

The vitamins, minerals, enzymes and herbs contained in NuVet Plus® help to strengthen your pet’s skin and immune system against potential damage from flea bites, allergic reactions to flea saliva and secondary infections. Not only will NuVet Plus® help to strengthen your pet’s immune system against flea bites and flea bite-mediated complications, it is a complete formula that will help support all your pet’s internal systems.

Beneficial Ingredients

Listed below are a few of the NuVet Plus® ingredients that may be particularly beneficial for your dog or cat with fleas:

• Alfalfa – Alfalfa supplies many of the vitamins, minerals, amino acids (especially tryptophan), digestive enzymes and protein that a balanced diet requires, including the A, B-6, D, E, and K vitamins, beta-carotene, fiber and chlorophyll, calcium, magnesium, phosphorous, iron, potassium and several trace minerals. The alfalfa in NuVet Plus® builds a strong and healthy body that resists damage from flea bites and development of related complications such as flea allergy dermatitis, hot spots and secondary infections. Strong, healthy skin resists allergic reactions and hot spot wounds from forming.

• Amino acids – Amino acids provide a double blow against flea bites and related complications by strengthening the skin and coat against flea bites and increasing the antioxidant activity of certain enzymes. The amino acid L-Methionine is especially useful in strengthening skin against flea bites and flea bite allergies and aids in wound healing to prevent the development of hot spots.

• Blue green algae – This important nutrient contains ample amounts of chlorophyll, a natural detoxifier and blood cleanser that helps flush hot spot-mediated infections out of your dog’s body.  It strengthens the immune system, supports rapid wound healing, enhances red blood cell production and maintains nervous system health. Blue green algae supplementation builds a strong defense against flea bites and strengthens hypersensitive nerve sheaths against the itching response.
• Brewer’s yeast – Brewer’s yeast is a rich source of B complex vitamins; Vitamins B-1, B-9 and B-12, in particular, support and strengthen the nervous system against the itching response. Brewer’s yeast supplementation has also proven effective against the development of severe flea infestations.

• Cat’s claw (una de gato) – Cat’s claw is an ancient herb from the Peruvian rain forest that acts as an antioxidant, an anti-inflammatory and an immune system enhancer against flea bite-mediated allergic responses and infections. Its anti-inflammatory properties keep skin tissue inflammation to a minimum following a bite, and by doing so prevent hot spots from developing or at least minimize their damage.

• Evening primrose oil –Evening primrose oil contains high amounts of gamma-linolenic acid, an Omega-6 essential fatty acid essential to the stimulation and maintenance of skin and nerve cells. Studies have also shown that evening primrose oil relieves inflammation. With these properties, then, evening primrose oil helps reduce flea bite-mediated inflammation and itching. Less itching means fewer – or no – hot spots. 

• Pine bark extract – Pine bark extract contains Proanthocyanidins, which hold in check the enzymes that cause skin inflammation.

• Potassium (citrate) – Potassium is essential to nervous system health, particularly the transmission of nerve impulses such as the itching response. NuVet Plus® has chosen to include in its formulation potassium citrate, which is a highly bio-available source of potassium.

• Vitamin E – Vitamin E’s anti-oxidant properties strengthen the immune system against flea bite allergies and the development of flea bite-mediated infections.
