![]() Additional studies are required to validate these standards and create a clinical tool for growth monitoring in pet dogs.Ĭitation: Salt C, Morris PJ, German AJ, Wilson D, Lund EM, Cole TJ, et al. In the current study, a series of evidence-based growth standards have been developed to facilitate charting of bodyweight in healthy dogs. This suggested that growth could be described using size categories rather than requiring curves for specific breeds. ![]() For the remaining 4 breed curves, occasional deviation across centile lines was observed, but overall agreement was acceptable. For 20/24 of the individual breed centile curves, agreement with curves for the corresponding bodyweight categories was good. Five bodyweight categories were created to cover breeds up to 40kg, using both visual assessment and hierarchical cluster analysis of breed-specific growth curves. However, these shifts were small in comparison to inter-individual variability amongst dogs, suggesting that separate curves for neutered dogs were not needed. Neutering before 37 weeks was associated with a slight upward shift in growth trajectory, whilst neutering after 37 weeks was associated with a slight downward shift in growth trajectory. Over 100 growth charts were modelled, specific to different combinations of breed, sex and neuter status. Curves were displayed graphically as centile charts covering the age range 12 weeks to 2 years. Growth centile curves were constructed using Generalised Additive Models for Location, Shape and Scale. Electronic medical records were used to generate bodyweight data from immature client-owned dogs, that were healthy and had remained in ideal body condition throughout the first 3 years of life. The primary aim of this study was to develop evidence-based growth standards for dogs, using retrospective analysis of bodyweight and age data from >6 million young dogs attending a large corporate network of primary care veterinary hospitals across the USA. ![]() Limited information is available on what constitutes optimal growth in dogs.
