Like all uninvited guests, parasites have a pretty terrible reputation. Not only responsible for wreaking havoc on a pet’s comfort and well-being, they’re known to spread disease. There are some pretty major signs your pet might have fleas, but sometimes these can go unnoticed. Before long, you could have a full infestation on your hands. We’re here to help prevent this from happening to your pet and home, so you can have the relaxing, enjoyable summer you’ve been waiting for.  

Lyme disease is one of the most common diseases seen in New England, and has been spreading quickly across the United States over the past 20 years.  According to the Companion Animal Parasite Council, all 50 states had cases of confirmed canine Lyme disease in 2018.  In our small state of New Hampshire alone, there were 11,374 Lyme positive dogs reported.  

About Lyme Disease

Lyme disease was first diagnosed in 1983 due to an outbreak of arthritic symptoms in humans in the Lyme Connecticut area.  Lyme disease is a spirochete bacterium that is transmitted to dogs, humans, and many other mammalian species through tick bites.  The deer tick or the black-legged tick, lone star tick, American dog tick, and brown dog tick carry and can transmit Lyme disease.

Symptoms

Common symptoms of Lyme disease in dogs include intermittent lameness, decreased activity level, decreased appetite, and fever.  Dogs do not always show all four of these symptoms, but typically develop a combination of two or more when they become clinically ill.   Also, dogs who are not properly protected and are repeatedly exposed to Lyme-carrying ticks are at risk of developing certain types of kidney disease.  Before proper prevention was available, many dogs infected with Lyme disease died of a syndrome known as Lyme nephropathy.

Transmission

If a live tick is attached to a dog for over 36 hours, it can then begin to transmit Lyme disease.  Unlike people, dogs do not perform tick-checks on themselves; and they do not commonly develop the typical bullseye rash as seen in humans.  Therefore, we typically do not know that our canine loved ones have been infected with Lyme disease until they come up positive on a blood test or develop symptoms and are diagnosed by a veterinarian.  Plus, dogs spend much of their time sniffing around and playing in areas where ticks thrive, such as woods and tall grasses.  The key to reducing the risk of our pets developing Lyme disease is through prevention.

Prevention is Key

Just as it is with us, nightly tick-checks are very important to perform on our dogs to help keep them free of tick-borne diseases.  However, life gets busy and small ticks can be missed on a fur-covered dog.  Two other main keys to preventing our 4-legged loved ones from becoming infected with Lyme disease are through proper year-round preventives and vaccination.

Which Products to Use

Ticks are one of the hardiest creatures on our planet.  Contrary to certain “opinions” on the internet, homeopathic and holistic options are not effective to kill ticks or prevent them from transmitting tick-borne diseases.  Over the years, there have been many different types of (flea &) tick preventatives in a variety of formulations.

In 2014, the Food & Drug Administration (FDA)approved new prescription medications called Isoxazolines.  These are typically chewable tablets, which makes it easier to administer to dogs. By avoiding topical products, it also eliminates the possibility of local skin irritation and reduces contact of the product with human and feline family members. These medications have completely revolutionized our ability to protect our dogs from Lyme and other tick-borne diseases.  They are incredibly well-tolerated and work much faster and more reliably than any of the more traditional topical preventatives.  Here, at Hampton Veterinary Hospital, we recommend year-round use of Bravecto for the majority of our canine patients.  

Remember, prevention is the key to keeping our loved ones safe & healthy!

Heartworm disease (HWD) is a serious and potentially fatal disease in dogs and cats that is spread by over 30 species of mosquitoes. Adult heartworms live in the heart and lung blood vessels of infected animals; one pet can have up to 300 worms! Heartworms live for up to 5-7 years and produce millions of offspring that live in the bloodstream until they develop.

Heartworm disease occurs all over the world, but has been increasing in prevalence in the United States, and spreading further and further across the country. New England has been seeing a significant increase in heartworm disease in the past 3-5 years. According to the Companion Animal Parasite Council, there were 674 reported cases in New Hampshire alone in 2018.

Signs

The signs of HWD depend on a number of variables, but are typically due to heartworms clogging the heart and major blood vessels. Signs can include:

• A soft, dry cough.
• Shortness of breath, exercise intolerance.
• Weakness, listlessness, loss of stamina, collapse.
• RARELY – swelling of the legs and belly, weight loss, and some animals may die suddenly during exercise or excitement.

Diagnosis

Diagnosis of HWD is done by a blood test that can be run in the veterinary hospital. Following diagnosis, further testing is recommended (such as bloodwork and x-rays) to determine if the dog can tolerate the appropriate treatment.

Treatment

In dogs, treatment of HWD is complex, expensive, and can be painful – it involves antibiotics (Doxycycline), an injectable arsenic-based compound to kill adult worms, and steroids to help decrease the inflammatory response when the worms begin to die. Strict rest for several months is incredibly important, as exercise and excitement can lead to dangerous and sometimes life-threatening clots. As long as the disease is not significantly advanced, this disease is treatable. However, in more advanced cases, prognosis can be poor due to substantial damage to the heart, lungs, blood vessels, kidneys and liver. Unfortunately, there is no current treatment for cats.

Prevention

Prevention is so important when it comes to heartworm disease, for both dogs and cats. Preventing the disease prevents damage to the heart and lungs, and avoids a painful and expensive treatment process, as well as strict activity restriction. By preventing this disease, you and your pet can enjoy a life of play and adventure without restriction!

Here are a couple of excellent options for preventing heartworm disease that we recommend here at Hampton Veterinary Hospital:

1. Interceptor PLUS for dogs – a chewable tablet given monthly, year-round.
2. Proheart Injection for dogs – an injection given here at Hampton Vet, and lasts 12 months.
3. Revolution PLUS for cats – a monthly topical, applied year-round.
