At Pet Health Hospital we want to make sure that your cat or dog is free of parasites (intestinal, external, and heartworms). The dry and arid climate of Las Vegas makes the occurrence of these parasites less frequent than in other places in the United States. It does not mean that we do not see these problems in the valley, though. Screening for these diseases is included in our Canine Health and Feline Health Lifetime Care Programs. A Pet Health Hospital Veterinary professional will discuss and evaluate the environmental history (groomers, dog parks, boarding) and travel history of your pet to help determine if parasite prevention would be beneficial.
