New CAPC study shows Lyme disease is spreadingMay 7, 2019Research from the Companion Animal Parasite Council (CAPC) indicates seroprevalence of Lyme disease in dogs is not only increasing in the Northeast, where it is considered endemic, but also spreading into areas that were previously thought to not be at risk for this serious, zoonotic tick-borne disease. ("Seroprevalence" in this case refers to the prevalence of dogs exposed to Borrelia burgdorferi, the pathogen responsible for causing Lyme disease in the U.S. based on serologic tests—hereafter referred to as "prevalence.") Study results were published in the December 2018 issue of Environmetrics, the official journal of The International Environmetrics Society (TIES). This milestone study, titled "A Large-scale Spatio-temporal Binomial Regression Model for Estimating Seroprevalence Trends," suggests canine prevalence rates for Lyme disease are rising and that those rates are increasing most in areas where the pathogen has recently encroached. Specifically, exposure in dogs to B. burgdorferi is rising in states not traditionally considered to be areas of high Lyme risk. Significant increases in the percentage of dogs testing positive for exposure have also been seen in areas that have not yet reported significant human incidence. These findings suggest canine Lyme prevalence could serve as an early warning system for changes in …

CAPC forecasts higher heartworm infections in South Central, Southeastern statesApril 26, 2019The Companion Animal Parasite Council (CAPC) predicts in its newly released parasite forecast that heartworm occurrence will be higher than average this year . "We started providing our annual forecasts over eight years ago because of the dynamic and ever changing nature of parasites," says CAPC executive director, Christopher Carpenter, DVM. "Over the years, we have seen these diseases continue to move. Our annual forecast will alert pet owners to the risks this year and remind them our pets need to be tested and protected year-round." The council's forecast predicts these areas are the riskiest for parasite-related diseases: South Central and Southeastern states are expected to see a higher than average infections with heartworm. The areas of greatest concern are those along the Mississippi River from Northern Louisiana into Illinois. Areas with historically lower incidence of heartworm such as Indiana, Illinois, and Iowa, should note the predicted higher prevalence. The Appalachian region, the Atlantic Coast, Wisconsin, and Minnesota are seeing a high threat again for Lyme disease. Northwestern Minnesota is forecasted to be active with the transmission of the agents of anaplasmosis. Southern Central states, particularly Oklahoma, Arkansas, and Missouri are expected to see higher numbers of ehrlichiosis. To …
Informed pet owners more likely to give heartworm preventativesApril 24, 2019Pet owners who have regular and open discussions with their veterinarian are more likely to consistently give their animals preventatives. Not only that, but according to a new study by Ceva, those clients have fewer issues with their cost and actual administration. "Our research showed the most consistent users follow their veterinarian's recommended steps for preventing the disease," says Ceva's senior director of veterinary services and pharmacovigilance, Charles Johnson, DVM. "They also value and rely on their veterinarian's recommendations more than inconsistent and non-users." The study's goal was to look at why consumers don't use preventatives consistently. The results point to lack of education as the main culprit. Respondents reported they are often left uninformed about the risks and health issues their pet could experience by contracting the disease, and they are confused about how preventatives work in general. The other findings of the study are: • only 25 percent of dogs receive heartworm preventives on a regular basis; • only 33 percent of users have purchased heartworm preventives during the past year; and • one in four dog owners think they are giving a heartworm preventive, but are really just providing flea and tick protection. …
Why heartworm prevention begins in your practiceApril 24, 2019According to the American Heartworm Society (AMS), it is estimated more than one million dogs have heartworm disease. Spread by mosquitoes, heartworms live in the heart and pulmonary arteries of infected dogs and cats. Left untreated, the disease can lead to heart failure, as well as damage to other organs. To mark Heartworm Awareness Month, we asked Claire Walther, DVM, veterinary specialty operations at Zoetis Petcare, for her take on what veterinarians can do to better convey the need for heartworm prevention to pet owners. 1) What is the single biggest misconception among veterinarians regarding heartworm disease? Biologically, it is how missing one dose of a preventative medication can lead to the development of heartworm disease. We say it to our clients daily, but many of us couldn't explain why if a client asked. In my own practice, I struggled with the answer. Here is a 30-second sound bite I've used with my clients to help simplify what is a complex discussion. "Young heartworms are carried by infected mosquitoes, and it only takes one bite to transmit them to your dog.1 Once in your dog, the young heartworms live just underneath the skin for about a month—this …
Overland Park, Kans, tops list of heartworm cities for MarchApril 17, 2019According to Companion Animal Parasite Council's (CAPC's) top 10 list, Overland Park, Kans, was the number one city for heartworms in March. CAPC says annual testing is more important than ever to ensure dogs and cats are protected no matter where they live or travel. It also recommends year-round heartworm protection. "It takes just one heartworm-infected dog in an area to become a reservoir of infection, increasing the number of infected mosquitoes and ultimately spreading the heartworm parasite to unprotected dogs and cats," says CAPC board member, Michael Yabsley, MS, PhD, FRES, professor in the department of population health, College of Veterinary Medicine and Warnell School of Forestry and Natural Resources at the University of Georgia. According to CAPC, national frequency rates for heartworm have increased each of the last five years and are now up 20 percent from 2013 levels. The following U.S. cities have the highest percentage increase in positive heartworm tests for March: 1) Overland Park, Kans. 2) San Francisco, Calif. 3) Laredo, Tex. 4) Thousand Oaks, Calif. 5) Salinas, Calif. 6) Oceanside, Calif. 7) Clarksville, Tenn. 8) Portland, Ore. 9) Providence, R.I. 10) Jersey City, …
AHS releases new heartworm recommendationsApril 2, 2019The American Heartworm Society (AHS) has released its 2018 Canine Heartworm Guidelines. The guidelines recommend yearly screenings for dogs more than seven months of age, the use of heartworm preventive medications, and reduced exposure to mosquitoes. It also suggests veterinarians recommend the use of Environmental Protection Agency- (EPA-) approved mosquito repellents for heat-treating a pet patient's serum. It is especially important for pet owners in Texas to follow the guidelines as mosquitoes are extremely widespread, according to the Texas Veterinary Medical Association (TVMA). The most telltale signs a dog has been infected is a persistent cough, difficulty breathing, intolerance to exercise, decreased appetite, and weight loss, while cats will suffer from lethargy, vomiting, or asthma. It is very common for the first indication of heartworm to be a sudden collapse or death. Preventing the disease in dogs is easy, safe, and affordable, whereas treatment is not. There is currently no treatment for cats. Testing and treating for heartworm can be difficult, which is why prevention is key to protecting pets. See the website to view the updated guidelines.
Keep more flea and tick preventive purchases in-clinicMarch 20, 2019When pet owners needed to purchase parasite control products, they traditionally went to their local veterinarian. However, the influx of retail businesses (both online and brick and mortar) competing in this market has created a financial feasting frenzy on clinic profits. "We have moved from having a near monopoly on the sale of flea/tick products to the current situation where less than half of clients are now purchasing their flea/tick products from their veterinarian," says Lowell Ackerman, DVM, DACVD, an independent consultant, author, and lecturer. In most veterinary hospitals, pharmaceuticals represent 25 to 30 percent of revenue, according to Dr. Ackerman. As the bulk of that revenue comes from the sale of parasite control products, this "erosion" of sales is both significant and troubling. Reel 'em back in Reasons as to why pet owners have strayed beyond home base varies. Cost, convenience, and just not knowing the benefits of purchasing from their veterinarian are examples. When it comes to product pricing, veterinarians need to be competitive, but they don't need to be the low-price leader, according to Ackerman. "Clients see most noninjectable parasite control products as commodities, and it is easy for them to compare prices across different sources," …
Salt Lake City, Utah, tops the list of heartworm cities for February in the U.S.March 15, 2019Salt Lake City, Utah, was the number one city for heartworms in February according to Companion Animal Parasite Council's (CAPC's) top 10 list. The monthly report warns pet owners, veterinarians, and pet-related service providers of U.S. metropolitan areas with highest percentage increase in positive heartworm tests. CAPC is devoted to monitoring and reporting emerging threats to pets. "The new CAPC Top 10 Cities Heartworm Report demonstrates heartworm disease—transmitted by mosquitoes—is a national threat to pets who are increasingly vulnerable to this debilitating and potentially fatal illness in most communities across the country," says CAPC board member, Michael Yabsley, MS, PhD, FRES. These are the U.S. cities with the highest percentage increase in positive heartworm tests for February: 1) Salt Lake City, Utah 2) Alexandria, Va. 3) Riverside, Calif. 4) Topeka, Kans. 5) El Paso, Tex. 6) Paterson, N.J. 7) Chesapeake, Va. 8) Reno, Nev. 9) Modesto, Calif. 10) Boise, Idaho "It takes just one heartworm-infected dog in an area to become a reservoir of infection, increasing the number of infected mosquitoes and ultimately spreading the heartworm parasite to unprotected dogs and cats," Yabsley says. "This is why CAPC recommends monthly …
Boehringer Ingelheim launches initiative to fight heartworm disease in dogsMarch 6, 2019Boehringer Ingelheim is debuting Heartworm 2020, an initiative dedicated to increasing the number of dogs who receive heartworm disease prevention in 2019. The initiative comes in response to a report from the American Heartworm Society (AHS) that found a 21 percent increase in positive heartworm tests per clinic. "We knew we could help increase the number of dogs receiving the heartworm disease prevention," says Sarah Cloud, Heartgard brand director. "Heartworm 2020 addresses this issue at the grassroots level by asking everyone in the veterinary clinic to participate. If every clinic does their part to get 20 new dogs on prevention, that means 583,240 more dogs will be protected from this potentially deadly disease in 2019 than were protected in 2018." To help clinics accomplish the Heartworm 2020 goal, Heartgard Plus will give heartworm disease education tools and incentives to pet owners. Heartgard Plus will also provide clinics with tracking tools and educational resources for staff. "Helping clinics educate pet owners on the on-going risks of heartworm disease is the first step in increasing the number of dogs on prevention," says head of U.S. Pet Veterinary Professional Services, Zach Mills, DVM. "Heartworm 2020 will help educate pet owners on heartworm …
