Tailoring vaccine protocols to benefit the patient and practiceMay 22, 2019More and more pet owners are starting to question veterinarians and their staff about the need for vaccinating their pets due to misinformation on the internet, as well as sensationalized stories about pets who may, or may not, have experienced a vaccine reaction. Those in opposition of vaccines are passionate about their views, while those in favor are equally vehement on the subject. Is one side right and the other wrong, or is there common ground to be found? Likely a little of both. Not all is yet known about the immune system, and there is still research that needs to be done. As such, recommendations offered today are based on current information, with the full knowledge they could change in the future. Not what they used to be Vaccines were developed to help prevent infectious disease, which they do, and vaccine technology has advanced tremendously since the inception of vaccinology. Vaccine opponents often argue ingredients such as adjuvants (e.g. aluminum, mercury, formaldehyde, and foreign proteins) are reasons to not vaccinate, as they can be the cause of adverse advents. This was true in the past; however, many vaccines have been "purified" over the years through the removal of …

Is fear driving the anti-vaccine movement?May 22, 2019Vaccines are one of the most effective means for preventing disease ever developed and one of the great triumphs of scientific medicine. Widespread vaccination of children has dramatically reduced—and in some cases eliminated—infectious diseases that have plagued humanity for thousands of years. There is less research evidence for the impact of vaccination in companion animals, but there is ample reason to believe vaccines have been equally successful in dogs and cats.3–7 Any veterinarian old enough to remember the emergence of canine parvovirus (CPV) in the U.S. in the late 1970s, for example, would probably testify to the efficacy of vaccination in reducing the incidence of this disease.5–7 There also is compelling evidence showing the reduction of both canine and human rabies cases due to vaccination programs aimed at dogs.8–12 And similar to smallpox, the veterinary disease rinderpest was eradicated largely due to the use of an effective vaccine.13 Vaccines and autism Despite the evident success of vaccination in reducing morbidity and mortality, there has always been controversy about the practice.14 The introduction of widespread vaccination in children was initially met with resistance and legal challenges. There was fear about the safety of vaccines, as well as resistance rooted in …
Service dogs can lead to a better life for ownersMay 21, 2019Service dogs improve the quality of life for their owners, according to a new study. Due to an increase in demand for service dogs, researchers at Purdue University College of Veterinary Medicine determined a need for using standardized measures to look at the relationship between the human-animal bond and psychosocial outcomes among people with service dogs over a four-year period. Elanco Animal Health funded the study. "Our goal was to apply strong science in quantifying the effects these dogs can have on well-being," says Maggie O'Haire, PhD, associate professor of human-animal interaction at Purdue University. "The research also reveals the distinctive role a service dog may have in the lives of the families of those individuals." Of the 154 recruited participants, 97 people who used a mobility or medical service dog displayed better psychosocial health, including higher levels of social and emotional functioning, and better functioning at work and/or school in comparison to the 57 who were on a waiting list. "Previous smaller and chiefly qualitative studies have found preliminary evidence service dogs can have psychosocial benefits among individuals with physical disabilities, but the research has been limited," said Tony Rumschlag, DVM, director, consulting veterinarians, U.S. companion animal business …
Treat aspiration pneumonia like a bossMay 13, 2019With a 25 percent death rate, aspiration pneumonia should be taken seriously. Treatment traditionally includes hospitalization, IV fluids and antibiotics (often a cephalosporin combined with enrofloxacin), oxygen therapy, nebulization, and coupage.
ASU begins clinical study for cancer-preventing vaccineMay 10, 2019An Arizona State University (ASU) professor has begun a five-year clinical study examining the effectiveness of a cancer-preventing vaccine for dogs. Stephen Johnston, PhD, a scientist, professor at the School of Life Sciences, and director of the Biodesign Center for Innovations in Medicine, developed the vaccine over a span of 12 years. He says his goal is to change the way veterinarians treat cancer by preventing it before it can start. Over the course of the five-year study, 800 dogs will either be given the vaccine or a placebo and will be monitored. The University of Wisconsin (UW) School of Veterinary Medicine, Colorado State University (CSU) and University of California (UC), Davis are also participating in the trial. "We're testing a totally novel way of creating an anticancer immune response," says David Vail, DVM, DACVIM (oncology), professor and board-certified oncologist at the UW School of Veterinary Medicine. "The holy grail would be to prevent cancer as opposed to waiting for it to start and then treating it." The vaccine is designed to target common canine cancers, including lymphoma, osteosarcoma, hemangiosarcoma, and mastocytomas. At the beginning, two sets of vaccines will be given every two weeks and then annually. The …
Homemade cat food diets low on nutrientsMay 8, 2019Most homemade cat food recipes are unlikely to provide essential nutrients and some may even contain potentially toxic ingredients. Those are the results of a study by researchers at the University of California (UC), Davis who looked at 114 recipes from online sources and books written by non-veterinarians and veterinarians. While recipes authored by veterinarians had fewer deficiencies, the study found they were still lacking nutrients. Of the all the recipes studied, 40 percent did not provide feeding instructions and the rest lacked detail or were unclear. "Only 94 recipes provided enough information for computer nutritional analysis and of those, none of them provided all the essential nutrients to meet the National Research Council's (NRC's) recommended allowances for adult cats," says lead author, Jennifer Larsen, UC Davis School of Veterinary Medicine veterinary nutritionist. In addition, the study found many of the homemade cat food was lacking concentrations of three or more nutrients, with some missing up to 19 essential nutrients. Further, many recipes provided less than 50 percent of the recommend allowances of several essential nutrients, including choline, iron, zinc, thiamin, vitamin E, and manganese. The study revealed seven percent of the recipes included ingredients that are potentially toxic …

Experts weigh in on ear examsMay 7, 2019Ears. They're the bane of veterinarians and clients alike, not to mention the dogs and cats who must contend with itchy or painful ear conditions caused by environmental and food allergies, bacteria and yeast overgrowth, mites, foreign bodies, trauma, tumors, or polyps. Ear problems can spring from many different sources. That makes it essential to conduct a thorough exam, be familiar with some of the other disorders that can lead to ear problems, and know what to ask owners to bring out clues to the cause. Itch triggers Allergies are probably the number one cause of ear inflammation. Once ears become inflamed, secondary infections caused by overgrowth of normal populations of bacteria or yeast in the ear typically follow. The result is exudate, pain, and worsening inflammation. Young animals in multipet households or hoarding situations may pass ear mites (Otodectes cynotis) back and forth, especially if they aren't on a monthly preventive, are fed a poor diet, or are sick. Demodex canis is another mite that can affect young or old animals who are immune-suppressed. Less commonly, endocrine diseases (e.g. Cushing's or hypothyroidism), as well as certain autoimmune disorders, can cause ear problems. Take hypothyroidism. "Those dogs commonly will have …
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 …
Getting to the root of pyodermaMay 7, 2019Scaling, hair loss, papules, pustules, and epidermal collarettes. All are clinical signs pointing toward canine pyoderma. The culprit may seem clear at first glance; however, veterinarians must look at the bigger picture to address the underlining issue. It's important to first understand the meaning of pyoderma, particularly regarding the depth of infection, says Elizabeth Layne, DVM, Dipl. ACVD, clinical instructor at the University of Wisconsin-Madison, School of Veterinary Medicine. The most common form of pyoderma is superficial bacterial folliculitis, a bacterial infection of the upper part of the hair follicle, caused by Staphylococcus pseudintermedius. Deep bacterial infections (presented as swelling, nodular lesions, and oozing draining tracts) can occur, but that is a different diagnostic and therapeutic approach, Dr. Layne adds. Superficial bacterial pyoderma is almost always secondary to some kind of skin abnormality, such as atopic dermatitis. Other skin diseases (e.g. flea allergy dermatitis, sebaceous adenitis, or primary seborrhea) can also result in superficial pyoderma, Layne notes. Systemic illness or immune compromise may lead to superficial bacterial pyoderma as well. Since pyoderma commonly masks another condition, a vicious treatment cycle can ensue if the underlining problem isn't identified. "Veterinarians often recognize the signs of infection and treat with antibiotics …
