Cat owners do not provide more reliable weight estimates for cats compared with veterinary professionals in an emergency setting.

OBJECTIVES: The aim of the present study was to assess the accuracy of weight estimation in cats provided by pet owners, veterinary technicians, house officers (interns and residents) and attending clinicians in an emergency room (ER). An additional objective was to determine whether carrying the cat contributed to a more accurate weight estimate. METHODS: A total of 72 cats presented to an ER and were enrolled in the study. Pet owners, veterinary technicians, house officers and attending clinicians were asked to record the cats' estimated weights on individual data collection cards. The actual weights of the cats were then obtained and compared with participants' estimations. RESULTS: There were no significant differences between weight estimates provided by pet owners, veterinary technicians, house officers and attending clinicians. Similarly, neither the length of experience of the veterinary staff nor carrying the cat had an effect on the provision of a more accurate weight estimate. CONCLUSIONS AND RELEVANCE: Pet owners are no better at weight estimation of cats in the ER setting compared with veterinary professionals. Carrying the cat did not improve the accuracy of weight estimation among veterinary professionals. The mean cat weight of 4.9 kg could be used as an average cat weight in an emergency situation for an adult cat.

Pet owners provide a more reliable weight estimate for dogs compared to veterinary professionals in an emergency setting.

OBJECTIVE: To determine the accuracy of pet owners, veterinary technicians, house officers (interns and residents), and attending clinicians at estimating dog weights in a veterinary emergency room. ANIMALS: 272 dogs weighing over 2 kg presenting to the emergency room between June 1 and July 29, 2022. METHODS: Pet owners, veterinary technicians, house officers, and attending clinicians recorded the dogs' weight estimations on individual data collection cards. Pet owners were also asked to estimate their dogs' weight during the triage period. The dogs' actual weights were then obtained and recorded. RESULTS: Pet owners were more accurate than veterinary professionals at providing weight estimates for dogs. Weight estimates were accurate to within 10% of the dogs' actual weights for 67.9% (181/267) of pet owners. Forty-one percent (112/270) of attending clinicians, 35.3% (95/269) of house officers, and 35.4% (96/271) of veterinary technicians' weight estimates were within 10% of the dog's actual weight. There was no difference noted in the length of veterinary experience and ability to closely estimate the patient's weight. Overall, veterinary professionals were more likely to closely estimate the weight of large dogs compared to small dogs. CLINICAL RELEVANCE: The pet owner is most likely to provide an accurate weight for dogs and questions about the dog's weight should be directed to the client for situations in which a weight cannot be rapidly obtained.
