Although dog vaccination has been demonstrated to reduce and eliminate rabies in humans, during meetings there are often calls for further pilot studies. The assembled data proves that a widespread approach is now required. While zoonotic rabies has a minimal presence in developed nations, it is endemic throughout most of Asia and Africa, where it is considered to be a neglected tropical disease. In these areas, rabies causes an estimated annual mortality of at least 55,000 human deaths. Worldwide rabid dogs are the source of the vast majority of human rabies exposures. The World Health Organization (WHO), the Food and Agriculture Organization (FAO) of the United Nations and the World Organization for Animal Health (OIE) advocate a collaborative One Health approach involving human public health and veterinary agencies, with mass canine vaccination programs in endemic areas being the mainstay of strategies to eliminate dog-mediated human rabies. While post-exposure prophylaxis (PEP) is effective in preventing deaths in people exposed to rabies, it is comparatively expensive and has little impact on the canine reservoir that is the primary source of zoonotic rabies. Indiscriminate culling of the dog population is expensive and there is little evidence that it is effective in controlling rabies in non-island locations. Mass canine vaccination programs using a One Health framework that achieves a minimum 70% vaccination coverage during annual campaigns have proven to be cost-effective in controlling zoonotic rabies in endemic, resource-poor regions. Case studies, such as in Tanzania and Bhutan, illustrate how an approach based on mass canine rabies vaccination has effectively reduced both canine and human rabies to minimal levels. The multiple benefits of mass canine rabies vaccination in these cases included eliminating rabies in the domestic dog reservoirs, eliminating human rabies cases, and decreasing the rabies economic burden by reducing expenditures on PEP.
BackgroundAdherence to a prescribed therapeutic regimen is a critical factor for achieving medication effectiveness and therefore treatment success. In the case of companion animal ectoparasite control, suboptimal owner adherence to medication recommendations is thought to be a common cause of treatment failure, and previous reports have found pet owners applying an average of 4.0–4.6 monthly flea and tick treatments per year to their dogs. This study investigated: US veterinary hospital self-reported flea and tick prevention recommendations; dog owner recollection of these recommendations; dog owner opinion on flea/tick recommendations and estimated owner flea and tick medication adherence based on veterinary hospital purchase records.ResultsVeterinarians at 24 veterinary hospitals in 4 United States regions provided their flea and tick prevention recommendations. Five hundred fifty-nine dog owners, clients of the 24 hospitals, completed a survey evaluating their recollection of the hospitals’ recommendations and their opinions regarding required treatment frequency. Almost all veterinary hospitals in this study recommended 12 months of flea and tick prevention but only 62% of participating dog owners recalled this recommendation. The average owner response was that their dogs require 10.5 months of flea and tick prevention annually. Owner opinions were significantly different among U.S. regions with pet owners in the northeast U.S. believing that they needed significantly less canine flea and tick protection than pet owners in other parts of the United States. The estimated actual flea and tick prevention coverage was 6.1 months based on owner medication purchases over a 12-month period.ConclusionsIn the United States, dog owner opinions and actions show that their flea and tick treatment adherence falls short of veterinarians’ recommendations.
BackgroundVeterinary clinic transaction records from the USA were examined to determine dog owner purchase patterns for three prescription ectoparasiticides. In-clinic purchases of formulations of fluralaner (with 12-week duration per dose) were compared with dog owner purchases of afoxolaner and spinosad (both with 4 week duration per dose) in a population of 231,565 dogs over a 12 month period. Prior studies in human and animal medicine have suggested that patients more closely adhere to prescriber dosing recommendations when they receive a longer-duration medication.ResultsVeterinary clinic transaction records were examined for the period June 2014 through March 2017 using records from approximately 650 veterinary clinics. Ectoparasiticide purchase patterns were compared for two products (afoxalaner and spinosad) with monthly dosing and one product (fluralaner) with an extended (12 week) dosing interval. The average dog owner who obtained fluralaner purchased significantly more months of flea/tick protection (5.7 months) over the 12-month study period than the average dog owner that selected either afoxolaner (4.6 months) or spinosad (3.3 months). The proportion of dog owners who obtained only one dose of ectoparasiticide per 12-month period was 42% for fluralaner, 30% for afoxolaner and 37% for spinosad. The proportion of dog owners who obtained 2 doses or less per 12-month period was 67% for fluralaner, 52% for afoxoalaner and 67% for spinosad. Owners that obtained fluralaner were significantly more likely to obtain 7.0–12.0 months of flea and tick protection and significantly less likely to purchase 1.0–6.9 months compared with dog owners who purchased afoxolaner or spinosad.ConclusionsDog owners who obtained a flea and tick medication with a longer duration of action acquired significantly more months of protection in a year than dog owners who obtained shorter duration (1 month) products. Dog owners were better able to adhere to veterinary recommendations on ectoparasites control with a longer-acting flea/tick medication.
BackgroundDoses of flea and tick medication acquired by dog owners over a 12 month period were determined from veterinary hospital transaction records in Spain. The number of months of flea and tick protection potentially obtained by dog owners prescribed fluralaner, a flea and tick medication with a 12 week re-dosing interval, was compared with months of flea and tick protection obtained by dog owners prescribed monthly oral or spot-on products. Prior studies in human and veterinary medicine have suggested that longer-acting medications benefit patients by providing improved adherence to provider recommendations.ResultsDog owners took home, on average, significantly more months of protection when they obtained the 12 week duration product fluralaner (4.3 months) than they did when they obtained other flea and tick products providing 1 month of protection [3.24 months (oral), 2.9 months (spot-on)]. Many dog owners (46–64%) obtained only one dose of flea and tick product each year, regardless of the duration of protection offered by the product. Significantly more dog owners obtained 7–12 months of protection when they were prescribed fluralaner (15.7%) by their veterinarians compared with dog owners prescribed monthly flea and tick products [6.8% (oral), 8.3% (spot-on)].ConclusionVeterinary prescription of fluralaner delivers more months of potential flea and tick protection as shown by dog owner acquisition of flea and tick medication. The use of a longer-acting medication requires the administration of fewer doses and may translate into better adherence to veterinary ectoparasite control recommendations.
Background: An extended duration flea and tick medication of the isoxazoline class (fluralaner) was introduced in 2014 in the United States and other countries. A survey was developed in 2016 to gauge dog owner adherence with veterinary recommendations around the administration of preventive flea and tick medications. Current fluralanerusing dog owners were also asked to compare their experience with opinions on monthly flea and tick products. Aim: To survey dog owners who were current users of fluralaner on their opinions, experiences, and attitudes around the administration of flea and tick medications to their dogs in light of current veterinarian recommendations. Methods: Dog owners in the United States (US), United Kingdom (UK), and Australia that gave fluralaner oral chews to their dogs were asked to compare their experience using fluralaner (12-week dosing) and monthly flea and tick medications. The survey responses of dog owners in the UK and Australia were compared against responses to a similar survey conducted in the US in 2017. Surveys were completed by dog owners who were in the clinic for any reason other than a sickness visit. Additionally, veterinarians that prescribed fluralaner from all three countries provided their annual flea and tick treatment recommendation for dogs. Results: A sample of veterinarians from the US, UK, and Australia that prescribe fluralaner recommend that dog owners obtain approximately 12 months of flea protection per year and 9–12 months of tick protection per year. A variable proportion of owners (22%–90%) reported that their dog participates in outdoor and social activities associated with an increased flea and tick exposure risk. A similarly variable proportion of owners reported prior experience of finding fleas (24%–50%) or ticks (18%–35%) on their dogs. All participating owners treated their dogs currently withfluralaner and most (68%–77%) had previously treated their dog with monthly flea and tick products. The convenience of 12-week dosing and less frequent dosing were the most frequently identified product qualities associated with their choice of an extended effect flea and tick treatment.Conclusion: Most veterinarians surveyed in this survey recommended year-round use of a flea and tick medication for dogs in the US, UK, and Australia. Dog owners recalled the veterinary recommendation for flea and tick prevention as 8–10 months per year. Most dog owners from the clinics in the US, UK, and Australia had used shorter-acting (monthly) flea/tick medications previously. The majority of those who currently gave fluralaner doses to their dogs were “satisfied” or “very satisfied” with the extended duration flea and tick product. Preference for a 12-week duration medication over monthly re-treatment was also high (82%–92%) in all three countries and was associated with convenience.
