Dietary Aspects of Weight Management in Cats and Dogs

Website Investigation of Pet Weight Management-Related Information and Services Offered by Ontario Veterinary Practices

Pet owners rely on information and advice from their veterinary practice to effectively manage their pet's weight. This study investigated weight management information and services displayed on practice websites in Ontario, Canada. Information collected from the websites of 50 randomly selected small and mixed-animal practices included practice and staff demographics and the type of weight management services, products, and information advertised or displayed. The most frequently advertised weight management service and product were nutritional counselling (34%) and therapeutic diets (25%), respectively. Current bodyweight measurement was advertised on just over half of the websites (54%), while physical therapy counselling was the least-advertised service (16%). Further statistical analyses were performed in an exploratory fashion to determine areas for future research. Binary logistic regression analyses were used to investigate the association between practice demographics and the type of weight management information advertised online. A maximum of two predictor variables were included in each regression model. Exploratory analyses indicated that when controlling for the number of veterinarians in each practice, having a higher number of veterinary technicians was associated with increased odds of a practice website advertising current bodyweight measurement by 80.1% (odds ratio (OR) = 1.80, p = 0.05). Additionally, when controlling the number of veterinary technicians, having a higher number of veterinarians was associated with increased odds of a practice website advertising sales of therapeutic diets by 119.0% (OR = 2.19, p = 0.04). When using corporate practices as reference, independently owned practices had decreased odds of advertising sales of treats and weight management accessories on their practice websites by 78.7% (OR = 0.21, p = 0.03). These preliminary results suggest that advertising weight management information is not prioritized on veterinary practice websites in Ontario, especially those with lower staff numbers. The findings of this study raise awareness on the current state of weight management promotion for pets on veterinary practice websites and highlight ways to improve upon a practice's online presence.

It discusses how to determine appropriate nutritional goals for individual patients, including comorbid patients with diabetes. Considerations for macronutrient and micronutrient modifications will be reviewed.

Assessing owners' readiness to change their behaviour to address their companion animal's obesity

BACKGROUND

Owner behaviour change in relation to management is critical for successful pet weight loss. The stages of change (SOC) can be used to conceptualise the process of intentional behaviour change. Clients may be more likely to make successful changes when practitioners use communication techniques appropriate for a client's current stage. The objective of this cross-sectional study was to assess pet owners' SOC in relation to managing the weight of their overweight or obese pet.

METHODS

An online questionnaire targeting dog and cat owners was distributed via snowball sampling. A total of 532 questionnaires were included in the analysis. Of these, 153 participants (28.8%) self-identified their pet's body condition score (BCS) as greater than 5 (on a nine-point scale). An adapted University of Rhode Island Change Assessment scale was completed by 119 of these participants (77.8%) to assess their readiness to change related to managing their overweight or obese pet.

RESULTS

Most participants were scored in the precontemplation (52.1%) and contemplation (42%) stages, where readiness to change is low. Owner assessments likely resulted in underestimation of pets' BCS.

CONCLUSION

The results offer preliminary insight into the SOC of owners who identify their pets as overweight or obese. Developing tools to assess and understand owners' readiness to change may be useful in informing veterinary professionals' communication approaches when engaging in weight management conversations.

Veterinary professionals’ weight-related communication when discussing an overweight or obese pet with a client

OBJECTIVE

Pet weight may be difficult for veterinary professionals to address with clients, particularly when pets are overweight or obese. The objective of this study was to characterize the communication processes and content of weight-related conversations occurring between veterinary professionals and clients.

SAMPLE

Audio-video recordings of 917 veterinarian-client-patient interactions involving a random sample of 60 veterinarians and a convenience sample of clients.

PROCEDURES

Companion animal veterinarians in southern Ontario, Canada, were randomly recruited, and interactions with their clients were audio-video recorded. Interactions were reviewed for mentions of weight, then further analyzed by means of a researcher-generated coding framework to provide a comprehensive assessment of communication specific to weight-related interactions.

RESULTS

463 of 917 (50.5%) veterinary-client-patient interactions contained an exchange involving the mention of a single patient’s (dog or cat) weight and were included in final analysis. Of the 463 interactions, 150 (32.4%) involved a discussion of obesity for a single patient. Of these, 43.3% (65/150) included a weight management recommendation from the veterinary team, and 28% (42/150) provided clients with a reason for pursuing weight management.

CLINICAL RELEVANCE

Findings illustrate opportunities to optimize obesity communication to improve the health and wellbeing of veterinary patients.

Owners' views of canine nutrition, weight and wellbeing and their implications for the veterinary consultation

OBJECTIVES

To investigate owners' views around canine nutrition and wellbeing, how these beliefs may differ according to the weight status of the dog and the implications for owner support approaches.

MATERIALS AND METHODS

A researcher-mediated questionnaire collected quantitative and qualitative data via structured interviews with dog owners (n=147) attending a country park in the East Midlands, UK, with a specific focus on views around canine nutrition and wellbeing.

RESULTS

Forty-four percent of owners cited "past experience" when determining what to feed, and only 9% of owners cited the veterinarian as a source of this information. When comparing chosen verbal description versus non-sequential body condition score images of the dog, only 22% of owners with overweight animals matched perceived verbal and visual appraisals, compared with 89% of owners of ideal weight dogs. Owners cited a good diet and regular exercise as important factors for canine wellbeing, but companionship with other dogs as the least important factor.

CLINICAL SIGNIFICANCE

Owners report being aware of the important association between canine nutrition and wellbeing, but their considered importance of factors influencing dog wellbeing may be influenced by their perceived weight status of the animal. Veterinarians may need to reframe owner discourse such that there is more routine discussion around weight and nutrition at every consultation. Furthermore, the use of non-sequential body condition score images could be a useful tool for a more considered opinion of canine weight status by owners.

Effect of food toys on owner-perceived quality of life of cats during a prescribed weight loss plan

OBJECTIVE

To determine the effect of a food toy on owner-perceived quality of life (QOL) of overweight cats during a weight loss plan.

ANIMALS

44 adult cats, 1 to 10 years of age with a body condition score (BCS) ≥ 7/9.

PROCEDURES

Cats were randomly assigned to the food toy or food bowl group. Cat owners completed an initial questionnaire and received a prescribed weight loss plan, bag of dry veterinary therapeutic cat food formulated for weight loss, measuring cup, and food bowl or ball-type food toy. Body weight and BCS were checked monthly. Owners completed a monthly questionnaire to assess their cat's QOL. Low-calorie vegetables were offered to 32 cats whose owners reported disruptive food-seeking behavior.

RESULTS

Of the 44 cats in the final analysis, 29 cats either lost ≥ 2 BCS points or achieved an ideal BCS. Owner-perceived QOL was higher at the final weigh-in, compared with that at the initial weigh-in. An effect of food toy versus food bowl on owner-perceived QOL was not detected. Of the cats offered vegetables, 28 cats would eat the vegetables with a palatability additive; 4 cats ate vegetables plain.

CONCLUSIONS AND CLINICAL RELEVANCE

Owner-perceived QOL was higher at the end of the study. Feeding overweight cats by use of a ball-type food toy did not influence owner-perceived QOL. Low-calorie vegetables can successfully be added to the weight loss diet to promote satiety; albeit, a palatability additive is likely needed. Further studies regarding feeding management for cats during a weight loss plan should be explored.

The effects of fiber source on extrusion processing parameters and kibble characteristics of dry cat foods

Cellulose and beet pulp have been commonly used in the pet food industry to increase the dietary fiber content of cat foods. However, pet food companies seek alternatives to these so-called byproducts. Miscanthus grass is grown for its fiber content and may serve as an alternative to traditional fibrous ingredients. The objectives of this study were to determine the effects of fiber sources on extrusion processing and kibble structure of cat foods. Three replicate batches of a complete and balanced foods for adult cats at maintenance each containing 10% of Miscanthus grass, cellulose, or beet pulp was mixed and kibbles were produced on a single-screw extruder. Feed rate, preconditioner water and steam, extruder screw speed, extruder water and steam addition, and knife speed were adjusted to achieve a wet bulk density of 330 g/L. After extrusion, kibbles were dried at 115.5 ºC to less than 10% moisture. Dried kibbles were coated with chicken fat and flavor enhancer. No effects due to fiber source were reported for extrusion parameters or kibble measurements (P > 0.05) with the exception of compression energy, wherein kibbles produced with cellulose required more energy to compress than those containing beet pulp (6,917 N mm vs. 3,591 N mm, respectively). In conclusion, tested fiber sources had no impact on extrusion parameters and most kibble characteristics. Kibbles containing cellulose required more energy to compress than kibbles containing beet pulp. Miscanthus grass could be used as an alternative to traditional fiber sources used to produce cat foods.
