Policies for the vaccination of cats and dogs in New Zealand veterinary practices

AIMS: To determine current practices and attitudes towards vaccination of dogs and cats of veterinarians in New Zealand; the methods used for informing clients on which vaccines to use, and the preferred site for vaccination of cats.

METHODS: A postal questionnaire was sent to all 483 listed veterinary practices in New Zealand during February 2012. Some questions were specific to pet dogs, cats, or working farm dogs. Responses were categorised according to practice type and geographical region of the respondent. Factors associated with respondent recommendation of annual vaccination with modified live viral (MLV) vaccines were examined using logistic regression analysis. Vaccines that were considered to be essential for every animal were defined as core; those that may be recommended for animals whose location or lifestyle placed them at risk, were defined as non-core.

RESULTS: There were 204 useable returns, equivalent to a response rate of 42.2%, distributed across the country. Annual vaccination with MLV vaccines of dogs was recommended by 54/198 (27.3%) respondents, and of cats by 107/181 (59.1%) respondents. Factors associated with the recommendation of annual administration of MLV vaccines to dogs included being a companion animal practice, a desire for policies on vaccination to be left to individual clinics, and having one veterinarian in the practice. Administration of the final vaccination for puppies was recommended at ≥14 weeks old by 55/185 (29.7%) respondents, and for kittens at ≥13 weeks old by 42/183 (23%) respondents. Of respondents that administered MLV vaccines annually, 62/103 (60.2%) believed reducing the frequency of vaccination would reduce income, and 52/103 (50.5%) considered it would have a negative effect on animal health. Advice to enable clients to decide which non-core vaccines were administered was given by 181/199 (91%) respondents. Factors considered when recommending a vaccine included consideration of risk to individual patients (190/203; 93.6%), requirements of boarding kennels/catteries (165/203; 81.3%) and clinic vaccination policy (142/203; 70%). The preferred site for administering MLV vaccines to cats was the dorsal neck or inter-scapular region (137/198; 69.2%). Amongst respondents, 18 wanted disease surveillance information to allow for truly informed decisions to be made about vaccination.

CONCLUSIONS AND CLINICAL RELEVANCE: Veterinarians can now compare their own vaccination practices and attitudes with those of veterinarians nationally, and internationally. There is a need for national surveillance information and for continued education of the public and commercial kennel and cattery owners for optimal vaccination strategies to be developed.     

Qualitative study of factors associated with antimicrobial usage in seven small animal veterinary practices in the UK

Responsible use of antimicrobials by veterinarians is essential to contain antimicrobial resistance in pathogens relevant to public health. Inappropriate antimicrobial use has been previously described in practice. However, there is scarce information on factors influencing antimicrobial usage in dogs and cats. We investigated intrinsic and extrinsic factors influencing decision-making of antimicrobial usage in first opinion small animal practices in the UK through the application of qualitative research methods.     

Primary hyperparathyroidism in dogs and cats

The most common cause of primary hyperparathyroidism in dogs and cats is a solitary adenoma involving an extracapsular parathyroid gland. The prognosis is excellent if the affected parathyroid gland is removed. Nonsurgical methods are discussed, although there are no current data to support any benefit over conventional surgery. The common postoperative complication to consider is hypocalcemia. Hypocalcemia can be successfully managed in these animals if it is anticipated and treated promptly.     

Mortality related to general anaesthesia and sedation in dogs under UK primary veterinary care

ObjectivesTo quantify and explore risk factors in dogs seen at primary care UK veterinary clinics for general anaesthetic (GA)/sedative-related death overall, in addition to neuter-specific procedures.Study designA nested case-control study within UK primary care veterinary electronic patient record surveillance programme, VetCompass, including over 300 UK veterinary practices.AnimalsA total of 157,318 dogs undergoing GA/sedative events.MethodsCases included dogs undergoing GA/sedative events between January 2010 and December 2013 with GA/sedative-related death recorded within 48 hours or 2 weeks of the event. Controls were randomly selected from dogs undergoing GA/sedation that did not die within these time periods. Risks of GA/sedative-related death for all surgeries and neuter-specific surgeries were estimated. Demographic and clinical associations with GA/sedative-related death were reported as odds ratios following multivariable logistic regression modelling. Statistical significance was set at 5%.ResultsFrom 157,318 dogs with a GA/sedative event, there were 159 (0.10%) within 48 hours and 219 (0.14%) GA/sedative-related deaths within 2 weeks. Within 89,852 dogs that underwent a neuter surgery, there were eight GA/sedative related (0.009%). Greater age, poorer American Society of Anaesthesiologists health status scores and more urgent procedures were associated with greater odds of death. Compared with mixed breeds, Rottweilers and West Highland White Terriers had greater odds and Cocker Spaniels had lower odds of GA/sedative-related death.Conclusions and clinical relevanceThe overall risk for GA/sedative related death was relatively low, particularly among the subset of dogs undergoing castration or ovariohysterectomy surgery. Associations and risk estimates may assist shared decision-making in clinical practice and provide benchmarks for audit.     

Number of cats and dogs in UK welfare organisations

It is not known how many cats and dogs are admitted to welfare organisations annually. This study produced the first estimates of the size of this population. A questionnaire was mailed out to welfare organisations during 2010, followed by a postal/email reminder and requests to non-responders for a telephone interview. The questionnaire covered areas including, the current number of cats and dogs being housed, how much of the year organisations were operating at full capacity as well as the number of cats and dogs admitted, rehomed and euthanased between January and December 2009. Responses were obtained from 54.8 per cent of organisations. Sixty-six per cent of cat welfare organisations and 48 per cent of dog welfare organisations reported that they operated at full capacity for 12 months of the year. The number of cats and dogs entering UK welfare organisations during 2009 was estimated as 131,070 and 129,743, respectively. This highlights the scale of the work performed by welfare organisations in caring for and rehoming unwanted cats and dogs annually and emphasises the urgent need to address concerns over the considerable number of these animals. This study has also produced useful baseline data, which will be essential for monitoring population changes over time.     

Numbers of dogs, cats, birds, and exotic animals in veterinary practices in the Netherlands 1994-2005 and possible consequences for the veterinary curriculum

The species of pets owned in the Netherlands are constantly changing, and it is important that veterinary practitioners have information about the number and species of pets presented in veterinary practice. Using the same methodology as in 1994, we determined the relative importance of the various pet species in 2005 and compared these data with those for 1994. The most notable findings were a 25% increase in the number of birds and exotic animals seen in small and large animal practices (from about 10% to about 12.5%), a doubling of the number of birds and tripling of the number of pigeons seen in mixed practices, a doubling of the number of reptiles seen in small animal practices, and a 10-fold increase in the number of fish seen in veterinary practices in general. There was a significant decrease in the proportion of cats (from 46% to 40.7%) and an increase in the proportion of dogs (from 44% to 46.7%). These trends in veterinary practice consultations did not parallel those seen in pet ownership. The increase in the number of birds (especially pigeons), reptiles, and fish seen in veterinary practice emphasizes the need to pay attention to these species in the standard companion animal curriculum.
