Symptoms of ear mite infestations usually include a combination of skin irritation; scratching around the ears, head and neck; shaking the head; ear discharge that may be dark and waxy (similar to lumps of coffee) and an unpleasant odor in the ears. Your veterinarian can confirm whether mites are present by looking at a sample of ear debris under a microscope.

Mites, especially Sarcoptes mites (also known as scabies mites), can cause severe itching, hair loss, and skin infections. Other symptoms may include red, scaly skin, starting in areas of fine hair, such as the armpits and groin. Your veterinarian can confirm a mite diagnosis by looking at a skin scraping sample under a microscope. With NexGard and NexGard SPECTRA you can protect your dog from mites. A single chew, once a month, treats and controls three of the most common mites that infest dogs: Demodex mites, Sarcoptes mites, and Otodectes ear mites.

Yes, NexGard and NexGard SPECTRA kill fleas quickly before they lay eggs, thus preventing further infestation of the environment. If there is a moderate to heavy environmental infestation, fleas may continue to emerge into the surrounding area for weeks or months due to the continued development of flea eggs, larvae, and pupae that are already present at the time of treatment, a phenomenon known as “resurgence.”  Therefore, more than one monthly treatment may be necessary to achieve control of moderate to heavy flea infestations. In areas where fleas are common year-round, monthly treatment with any of the NexGard chews should continue year-round without interruption. To minimize the likelihood of flea reinfestation, it is important to treat all animals within the home with an effective flea control product.
For more information, consult your Veterinarian.

Heartworms are transmitted from one dog to another by mosquitoes, which suck up tiny immature heartworms, called microfilariae, when they bite an infected dog. The larvae develop in the mosquito and are transmitted when the infected mosquito bites another dog.
 

Signs of heartworm disease can be subtle and difficult to detect until its later stages. As the disease progresses, signs may begin to appear. Contact your Veterinarian immediately if you notice coughing, difficulty breathing, sluggishness, and less energy for exercise in your dog. Adult heartworm causes serious damage to your dog's heart and lungs, and if left untreated, heartworm disease can lead to a serious and life-threatening illness.
 

Although it is possible to treat heartworm disease, it is difficult, expensive, and can be risky, especially in dogs that have begun to show clinical signs. It is best to prevent dogs from acquiring heartworm with a prophylactic treatment such as NexGard SPECTRA or HeartGard^® PLUS.
