Prevent Heartworm to Prevent a Tragedy

preview full Prevent Heartworm

Heartworm disease, which infected mosquitos transmit to dogs and cats upon biting them, can cause serious complications and even death. A single adult heartworm can grow up to 12 inches and live for up to five years inside the body of a host animal. Female heartworm can also reproduce inside of your pet. A mature heartworm typically lives in the pulmonary arteries or right ventricle of the heart. When multiple heartworms are present, they invade the right atrium as well. Some of the common symptoms of heartworm infestation include:
·      Persistent Coughing
·      Fatigue not caused by exertion or relieved by rest
·      Appetite loss
·      Weight loss
·      Vomiting 
·      Lethargy
However, some animals don’t display any symptoms at all until it is too late to treat the infestation. That is why heartworm prevention is so important. At Grantsburg Animal Hospital, we can start a puppy on heartworm medication at eight weeks of age without testing him first. By age six months, we need to obtain a negative heartworm test in order to prescribe preventive medication. Dr. Palmquist can determine if a dog has heartworm with a simple blood test. We diagnosed 11 positive cases of heartworm in 2015.
Although heartworm infestation in cats is far less common, it does occur. Because of their smaller size, cats can have serious affects from a single worm. In some cases, the first indication that a cat has heartworm is her sudden death. Coughing and breathlessness are the most obvious clues of the presence of heartworm in a cat. An infestation is more difficult to detect in cats and requires several blood tests to rule out other conditions. If your pet tests positive for heartworm, we customize our treatment approach depending on the number of worms and the severity of the symptoms.
Let Us Help You Select the Best Heartworm Preventive for Your Pet

It can be challenging to know which type of heartworm medication to choose for your dog or cat. Typically, we only recommend oral heartworm medication that also controls internal parasites. A topical spot-on or an injectable medication are additional possibilities. Some of the factors Dr. Palmquist considers when making a recommendation are your pet’s species, age, lifestyle, and whether he normally accepts medications without a fight. After visiting Grantsburg Animal Hospital, you can easily order heartworm medications for dogs and cats from our online store. Please don’t hesitate to contact us if you have additional questions or concerns about heartworm prevention or treatment.

How to Keep Your Pet Safe During Lyme Disease Season


According to the American Lyme Disease Foundation, the disease is abundant throughout most of Wisconsin and either abundant or common in at least half of Minnesota. Now that spring is here, your pets have the opportunity to spend more time outdoors and in wooded areas where the ticks that carry Lyme disease thrive. Grantsburg Animal Hospital encourages you to learn about this serious and sometimes fatal tick-borne illness so you have all the resources you need to protect your pet.

How Ticks Transmit Lyme Disease to Dogs and Cats
Several species of ticks carry Lyme disease, including the American dog tick, black-legged (deer) tick, brown tick, and the Rocky Mountain tick. Some of these species are so tiny that you cannot see them, even when they are fully engorged with your pet's blood. Since these ticks require blood to survive and reproduce, they bite the host animal and can remain lodged in the body. The bacteria that causes Lyme disease is transmitted through the tick's saliva. 

A tick needs to remain attached to the animal for at least 48 hours for Lyme disease transmission to occur. Fortunately, many drop off after they feed and before they can infect the animal with Lyme disease. Another positive is that only a small percentage of dogs end up developing the disease even when the tick remained on their bod past 48 hours. The disease is rare in cats. Pets that do develop Lyme disease typically do not show any symptoms for two to five months.

Recognizing Lyme Disease in Your Pet
Be sure to check your pet daily for ticks, especially if you live in a wooded or rural area. Due to their tiny size, you need to run your fingers down your pet's back and tail as well as check her underside. It’s essential to check the head and ears since these are the most common areas for ticks to lodge. If you find one, pull it out with a pair of tweezers and place it in a jar of rubbing alcohol to kill it. The most common symptoms of Lyme disease in companion animals include f
ever between 103 and 105 degrees, lethargy, loss of appetite, joint swelling and stiffness, swollen lymph nodes, lameness, and frequently shifting weight between legs.

Preventing Lyme Disease
In 2015, we confirmed 259 cases of Lyme disease at Grantsburg Animal Hospital. Because Lyme disease can be deadly in some animals, we encourage you to contact us immediately if you suspect that your pet may have developed it. This is true even if she is not yet displaying any symptoms.

The easiest way to prevent your pet from developing this disease is to keep ticks away from him. We recommend Bravecto flea and tick prevention for dogs, which is available in our online store. This comes in the form of a chew that you only have to remember to give four times a year. Ticks die when ingesting the Bravecto and fall off your pet's body. We also carry several flea and tick options for cats in our online store. Lastly, be sure to discuss the possibility of getting the Lyme disease vaccine with Dr. Palmquist. He will evaluate your pet's lifestyle and risk factors to determine if the vaccine would be appropriate.

Make Sure Your Pet is Protected from Common Parasites This Spring

preview full Common Parasites This Spring
In just a few short days, it will officially be spring in Wisconsin and Minnesota. Like any Midwesterner, you have probably been looking forward to the change of season for months. The warmer weather means more time outdoors for your pets, which unfortunately increases their risk of flea, tick, and heartworm infestation. 

During Flea and Tick Prevention Month, we encourage you to learn more about the damage caused by these parasites and the importance of year-round protection. To fully appreciate the importance of parasite prevention, consider that we diagnosed 562 cases of tick disease and 11 cases of heartworm disease in dogs during 2015.

According to the American Association for the Prevention of Cruelty to Animals, fleas are the most common external parasite that threaten the health of companion animals. They live from two weeks to one year and can produce millions of offspring in that time. Fleas are wingless insects that survive by feeding on the blood of a host animal. Signs that your dog or cat could have fleas include:

• Loss of fur
• Flea dirt in the coat that looks like grains of sand
• Persistent scratching, biting, or licking skin
• Developing allergies
• Flea eggs that appear as tiny white grains
• Tapeworm
• Pale gums and lips
• Developing cat scratch disease
• Anemia due to severe blood loss

Ticks also feed on the blood of host animals, although their presence does not cause as many obvious symptoms as fleas. To starting feeding on host blood, a tick first burrows its head into the skin. It's most common to find ticks on your pet's head, ears, neck, and feet. Unlike fleas, pet owners can usually spot a single tick with the naked eye. They are the size of a pinhead before they bite and then swell up as they gorge with blood. If you spot one, pull it out with a pair of tweezers and then place it in a jar containing alcohol to kill it. 

Ticks can inflict pets with serious diseases, including Lyme disease, Rocky Mountain Spotted Fever, and Anaplasmosis. Additional complications include anemia from blood loss, paralysis, and skin irritation. If your pet displays signs of an infection such as fever, vomiting, or lethargy, contact Grantsburg Animal Hospital immediately for an evaluation.

Your pet can get heartworm from a single mosquito bite if the mosquito has bitten an infected animal. Once inside your pet's body, the heartworm can grow to a foot long and live in the heart, lungs, and blood vessels of your pet. Heartworm can also reproduce rapidly, causing lung disease, organ failure, or even death. Sadly, some pets don't display any symptoms until heartworm disease is advanced. Typical signs of heartworm infestation in dogs include a persistent cough, loss of appetite, fatigue, intolerance of exercise, and weight loss. Cats display the same symptoms in addition to vomiting and difficulty walking.

Our Recommendations
The veterinarians at Grantsburg Animal Hospital recommend Bravecto for the best protection from fleas and ticks for dogs. Bravecto is a chewable supplement that comes in several different flavors and sizes. Your dog thinks he is getting a treat and you only have to give it to him once every three months. We carry several additional canine and feline flea and tick prevention products in our online store and in all three clinics, including collars, shampoos, drops, and spot-on kits. 

We also recommend Heartgard to protect against heartworm for both dogs and cats.  Heartgard is a monthly chew that provides your pet with unparalleled protection from this aggressive parasite.

March is National Pet Food Nutrition Month

The Academy of Nutrition and Dietetics originally started National Nutrition Month to call attention to the importance of nutritious food choices for children and adults. The awareness campaign has since evolved to include the veterinary industry. At Grantsburg Animal Hospital, we see first-hand the effects of both good nutrition and poor nutrition. Some of the consequences of the latter include malnutrition, obesity, skin and coat problems, allergies, and an increased risk of diabetes, heart issues, and cancer. 

Choosing the Most Nutritious Food for Your Pet
While nobody wants their pet to experience such serious health problems, it can be hard to select the most nutritious pet food. Before making a purchasing decision, it’s important to consider your dog or cat’s age and special health requirements. Many companies that manufacture pet food tailor their product to age categories and common issues such as a sensitive stomach. It’s also important to check the pet food label. Both dogs and cats benefit from food that has animal protein as its first ingredient.

For dog food, other important ingredients include water, fats, carbohydrates, vitamins, and minerals. Cat food should contain antioxidants, fat, and fiber. Pet food labels are regulated by the American Feed Controls Office and must contain the following:

• Product name
• Ingredient list
• Guaranteed analysis that states the percentage of main nutrients in the pet food
• Nutritional adequacy statement
• Feeding guidelines
• Net quantity statement
• Manufacturer’s name and address

While this list sounds impressive, it leaves room for many omissions. For example, ingredients added by anyone other than the original manufacturer do not have to be included on the label. Additionally, a manufacturer can add words such as premium or all-natural to the packaging without having to create a higher quality product. That’s why knowing how to decipher a dog or cat food label is important. For additional information on how to interpret each of the above categories, go to the website Dog Food Scoop or Cat Food Analysis.

If you still feel uncertain about which type of food and brand is best for your dog or cat, our staff is happy to help. Just give us a call or bring it up at your pet’s next wellness exam. Your pet’s veterinarian will consider individual factors such as species, breed, age, weight, and general health before making a recommendation. 

Grantsburg Animal Hospital carries Purina Pro Plan and Purina Prescription diets in all three of our clinic locations located in Grantsburg and Frederic, Wisconsin and Wild River, Minnesota. The Purina brands are also available from our online store. If your pet has allergies, we encourage you to consider feeding him or her Taste of the Wild grain-free food. This specialty food is also available in all three clinics.
