Parasite Prevention and Control

Protecting Your Pets Against Pests and Parasites With Help From Your Casper Veterinarian

No matter how thoroughly domesticated your "indoor pets" may be, they're still prone to the tiny intruders known as pests and parasites. These unwanted guests literally feed on animals, with results ranging from irritation and infection to death. The special animals in your life depend on you to protect them from these dangers -- and you can depend on Westside Animal Hospital. Our animal hospital in Casper can provide the necessary preventative programs and treatment measures to safeguard your pet's well-being.

Worm, Flea and Tick Prevention With Your Casper Veterinarian

Worms are one of the most common categories of pet parasite. Whipworms, roundworms, hookworms and other worms typically originate as eggs in animal feces which can easily be transferred from pet to pet, causing severe digestive problems and other dangers. Other worm parasites such as tapeworms and heartworms enter pets' bodies through mosquito bites. Heartworm is an especially dreaded kind of infestation for its ability to cause heart and lung failure. This sad decline in your pet's health may go on for years (in dogs), or it may even cause sudden death (in cats). To make matters worse, treatment for heartworm infestation is a long, difficult process in dogs, while cats have no safe treatment option at all.

External parasites such as fleas and ticks are no less of a problem. In addition to causing tapeworm infestations, flea bites can transfer diseases such as plague, cat scratch disease, and haemobartonellosis; severe infestations can even cause fatal blood loss in small or weakened animals. Ticks spread Rocky Mountain spotted fever, Lyme disease, ehrlichiosis, and anaplasmosis. Both types of pests can cause allergic dermatitis, with obsessive scratching creating opportunities for skin infections.

Turn to Your Casper Veterinarian for Flea, Tick, and Heartworm Prevention

Your Casper veterinarian at Westside Animal Hospital, Dr. Doug Johannessen or Dr. Laura Johannessen, can help you minimize your pet's vulnerability to parasites of all kinds. Many of today's preventative medications provide protection against multiple threats; for instance, some heartworm prevention products also guard against hookworms, roundworms, fleas and tapeworms. We may recommend more than one product to make certain that your pet enjoys thorough protection against different pests and parasites.

Flea and tick prevention options include oral, topical and collar-based products. Collars typically last longer than ingested flea and tick prevention products, which must be administered monthly, but some pets are allergic to them. We can select the right flea, tick, and heartworm prevention program for your individual pet. We can also recommend best practices for keeping your home as pest-free and parasite-free as possible, from cleaning up animal feces immediately to vacuuming your upholstery on a regular basis. (Many of the same parasites that afflict pets can trouble humans too!)
