While fleas are not much of a problem in the arid Phoenix Valley and Sonoran Desert compared to humid regions, heartworms, ticks, and intestinal parasites still pose year-round risks to dogs and cats in Cave Creek, Carefree, North Scottsdale, New River, and Desert Mountain. At Desert Forest Animal Hospital, we evaluate your pet’s age, lifestyle, and health to create a customized parasite prevention plan that keeps them healthy and comfortable.
Based on this American Heartworm Society map American Heartworm Society, the incidence of Heartworm disease in increasing in Arizona. Heartworm disease is a serious, potentially fatal condition spread by mosquitoes. In Arizona, mosquitoes remain active much of the year thanks to irrigation, pools, and urban water sources. Heartworms live in the heart, lungs, and blood vessels, causing severe lung disease, heart failure, and organ damage. Wild animals like coyotes and foxes common in the North Valley area help spread the disease.
Ticks found in the Sonoran Desert can transmit Rocky Mountain spotted fever and other illnesses. Symptoms include lethargy, joint pain, decreased appetite, skin lesions, vomiting, neurological problems, and depression.
Intestinal parasites (roundworms, hookworms, whipworms, and tapeworms) are picked up from soil, wildlife, or other pets. They cause vomiting, diarrhea, weight loss, anemia, and poor coat quality. Many are zoonotic and can affect humans too.
Although fleas are far less common here than in other parts of the country, they can still appear seasonally or indoors and lead to flea allergy dermatitis (intense itching, skin inflammation, sores, and hair loss) plus tapeworm infestations.
Small puppies, kittens, and senior pets are especially vulnerable to anemia from heavy parasite loads, which can become an emergency.
We strongly recommend year-round heartworm prevention for all dogs and cats in Cave Creek and surrounding areas. Annual heartworm testing during wellness exams helps catch any issues early. Prevention is simple, affordable, and far easier than treatment.
Ticks are active in our local desert environment. Consistent prevention protects against tick-borne diseases that can make your pet very sick.
Regular fecal exams (recommended at least yearly) detect intestinal parasites before they cause problems. We provide deworming and prevention strategies based on your pet’s risk level.
Desert Forest Animal Hospital carries a variety of safe, effective options and will help you choose the best one for your pet:
