Results of a web-based health survey of retired racing Greyhounds.

BACKGROUND: Adoption of retired racing Greyhounds has become increasingly popular during the past decade. To date, research has focused on the physiologic and clinicopathologic peculiarities of Greyhounds but there is little published information on disease prevalence in the breed. OBJECTIVE: The objective of this study is to determine the prevalence of disease in retired racing Greyhounds. ANIMALS: In this study, 747 Greyhounds were used. METHODS: A standardized survey method was used, and survey responses were collected by an Internet survey. Owners could answer a survey for every Greyhound that they had owned since January 1, 2005. RESULTS: Of the 692 eligible participants, 441 (63.7% response rate) completed surveys for 747 Greyhounds. The mortality rate for Greyhounds within the 2-year period was 15% (113 of 747 died). The most common cause of death reported was cancer (66 dogs, 58%), and the most common type of cancer listed as the cause of death was osteosarcoma (28 dogs, 25%). The most commonly reported groups of diseases or disorders were skeletal (232 dogs, 33%), skin (197 dogs, 28%), digestive (132 dogs, 18%), cancer (94 dogs, 13%), and endocrine (85 dogs, 11.9%). Forty-five percent of Greyhounds diagnosed with cancer and 6% of the overall population had osteosarcoma. CONCLUSIONS AND CLINICAL IMPORTANCE: The results of this study can be used by veterinary researchers to continue to investigate the most common diseases in this population. As more retired racing Greyhounds enter the pet population, the results of this study will help educate veterinarians and owners about the most prevalent diseases in the breed.

Evaluation of owner education as a component of obesity treatment programs for dogs.

OBJECTIVE: To compare results of a conventional obesity treatment program with those of an obesity treatment program that included education of owners of obese dogs. DESIGN: Nonblinded prospective clinical trial. ANIMALS: 60 obese dogs with a body condition score (BCS) of 8/9 or 9/9. PROCEDURE: Dogs were randomly assigned to control or owner education (EDU) treatment groups. A 6-month weight loss period was followed by an 18-month weight maintenance period. Daily caloric intake to induce loss of 1% of body weight/wk was calculated for each dog after assessment of prior diet history. The daily caloric intake for weight maintenance was estimated to be 20% greater than that calculated for weight loss with adjustments of +/- 5% as required. Weight and BCS were recorded monthly for each dog. Owners of dogs in the EDU group were required to attend monthly classes that addressed nutrition-related topics during the 6-month weight loss period. RESULTS: Dogs in both treatment groups had significantly lower weight at the end of the weight loss period, compared with initial weight. Mean weight loss at 6 months was 14.7% in the control group and 15% in the EDU group; this difference was not significant. During the weight maintenance period, percentage weight loss was maintained in both treatment groups. Mean changes in BCS at 6 months (relative to time 0) were -1.5 in the control group and -1.7 in the EDU group. At 24 months, mean changes in BCS (relative to time 0) were -2.1 in the control group and -2.2 in the EDU group. No significant differences in BCS were identified between treatment groups at either 6 or 24 months. CONCLUSIONS AND CLINICAL RELEVANCE: Mean decrease in BCS of 2 and mean weight loss of 15% were achieved and maintained in all dogs. An obesity treatment program that included dietary changes and monthly weight checks during the weight loss and weight maintenance periods was sufficient to achieve these results.
