For dogs, Barstow Animal Hospital recommends year-round flea and tick preventatives, as these parasites are common in the local area and can transmit diseases like Lyme disease and Rocky Mountain spotted fever. The hospital also advocates for monthly heartworm prevention to protect against the dangers of heartworm disease, which can cause irreversible damage to a dog's heart and lungs if left untreated. Intestinal parasites, such as roundworms, hookworms, and tapeworms, are also common in dogs and can be easily transmitted through contaminated water or soil. Regular fecal examinations at the hospital ensure that intestinal parasites are promptly detected and treated.

Similarly, for cats, parasite prevention at Barstow Animal Hospital involves a multi-faceted approach. Cats are also susceptible to flea infestations, and while ticks are less common in indoor cats, they can still occur if the pet has access to outdoor environments. The veterinary staff recommends flea and tick preventatives as well as heartworm prevention for outdoor cats or those who spend time in areas with high mosquito populations. Intestinal parasites are a concern for cats too, as they can become infected by ingesting contaminated prey or soil. Barstow Animal Hospital provides routine deworming services to protect cats from these parasites, ensuring they remain healthy and comfortable.
