External parasites live on the skin and in the ears of your pets. They cause irritation to the skin which can often lead to more advanced skin problems such as infections, hair loss, itchiness, increased thickness and pigmentation. Many external parasites are communicable from pet to pet and from pets to people.

The most common external parasites that we see affecting dogs and cats in our area are:


Ear Mites

Sarcoptic Mange


Fleas and ticks suck blood from our pets of Alta Loma, Rancho Cucamonga, Upland, Ontario, Claremont, Fontana, and the Inland Empire can cause anemia. They may also transmit diseases such as Lyme’s Disease (Borrelliosis) and Plague. Mange mites and ear mites are very itchy and will cause the pets great distress if left untreated.

We rely on visual inspection and microscopic examination of skin scrapings to diagnose these infestations. Once we make the diagnosis, then therapy can be started with a variety of drugs.

To prevent Flea and Tick infestations our veterinarians can use either a topical drug such as Frontline Plus.

Frontline Plus is administered on the neck of the pet once a month. This remarkable drug continues to kill both fleas and ticks for 4 weeks or more. It will not wash off during bathing or if the pet swims or gets wet in the rain. It is safe in pets as young as 9 weeks of age.

If ticks are not an issue for your pets, we offer a once-a-month tablets to control fleas. In addition to controlling fleas, these once-a-month tabletss control heartworm disease and the major intestinal parasites (roundworms, hookworms and whipworms).
