If you live in North Texas, your dog needs parasite protection all year round. Our warm, humid climate means fleas, ticks, and mosquitoes are always active. If your dog is not on a regular prevention regimen, they are at risk for diseases like heartworm. Some of these parasites can also affect humans. Fleas can infest your home and ticks can spread Lyme disease, so keeping your dog protected keeps everyone safer.
Heartworm Prevention: The One You Cannot Afford to Skip
Because mosquitoes spread heartworm, every dog in Texas is at risk. Mosquitoes carry heartworm larvae and transfer them directly into your dog’s bloodstream when they bite. The larvae will then grow into worms that can be up to a foot long and live for seven years.
But because it takes about six months for heartworm larvae to mature, it may be some time before your dog shows signs of infection. Symptoms include coughing, fatigue, loss of appetite, and weight loss. While deworming treatments will get rid of the worms, by that time they may have already caused serious damage. Prevention is a much better way to go.
Dogs in Texas need to take heartworm medication once a month, and their stool should be tested for heartworms at least once a year.
Why Your Dog Needs Protection from Fleas and Ticks
Fleas are annoying, itchy, and dirty. They also spread a lot of nasty diseases. In dogs, fleas can cause dermatitis, anemia, tapeworm infections, and other illnesses. Unfortunately, some of these flea-borne diseases can spread to humans as well. In fact, Texas has some of the highest rates of murine typhus, a bacterial infection that gets transmitted through flea feces.
Ticks are a cause for concern as well. Brown dog ticks are common across Texas, and lone star ticks are widespread throughout the state. These parasites can transmit Rocky Mountain spotted fever, Lyme disease, ehrlichiosis, and other serious illnesses. And because there are no vaccines that prevent tickborne diseases in dogs, flea and tick prevention is the best route to take. Whether you use a flea and tick collar or give your dog a pill, when you protect your dog you’re protecting yourself, too.
Flea, Tick, and Heartworm Medication for Dogs: What You Need to Know
There is a lot of variety in parasite prevention products, and not all of them cover everything. Some products cover fleas only. Some cover fleas and ticks. Some include heartworm prevention as well.
Here’s what you need to remember:
- Heartworm prevention medication requires a prescription. Your dog will also need a negative heartworm test before starting.
- Flea and tick products vary in effectiveness. For instance, topicals have to be applied frequently, while chewable pills last longer. And over-the-counter products do not work as well as prescription medications.
- Not all products are safe for all dogs. Some breeds and very young or old dogs may need different doses, so checking with your vet matters
The best way to protect your pet is to ask your vet for a prescription. They will recommend the best options for your dog’s lifestyle, and risk factors and determine the correct dose for their health history, breed, and size.
