Objective—To determine the spatiotemporal gait characteristics and associated covariates of clinically normal dogs and dogs with spinal cord disease.

Animals—42 clinically normal dogs and 24 dogs with myelopathy at spinal cord segment T3-L3.

Procedures—Gait was analyzed for velocity, stride length, stride time, stance time, and swing time and compared between groups with consideration of covariates, including height, weight, velocity, sex, and age.

Results—By use of multivariate regression, dogs with neurologic signs, compared with clinically normal dogs, had decreased stride time, stance time, and stride length in the forelimbs and increased swing time in the hind limbs.

Conclusions and Clinical Relevance—Use of spatiotemporal gait characteristics appears to have potential for use as an outcome measure for dogs with neurologic disease.

To compare measurements of crude fiber (CF) and total dietary fiber (TDF) for various dog foods and their effect on the calculated nitrogen-free extract and metabolizable energy (ME) content, and to compare label-guaranteed and laboratory-analyzed macronutrient values.


51 dog foods fed to client-owned dogs with osteoarthritis.


Foods were analyzed for dry matter, ash, crude protein, acid-hydrolyzed fat, CF, and TDF. Metabolizable energy was calculated by use of a formula with modified Atwater factors and formulas recommended by the National Research Council that included both CF and TDF values. Linear regression analysis was performed to determine the correlation between CF and TDF values.


Only a few foods failed to conform to the guaranteed analysis for all macronutrients except for CF, in which approximately 40% of the foods exceeded the guaranteed maximum values. The CF and TDF values were moderately correlated (r = 0.843). Correlations among CF- and TDF-based ME estimations were moderate with use of the modified Atwater formula and strong with use of the National Research Council formulas (r = 0.86 and r = 0.91, respectively).


Values for CF were the most variable of the macronutrients of the evaluated dog foods and results suggested that CF is an incomplete and inaccurate measurement of dietary fiber content and, thus, its inaccuracy may lead to inaccurate and variable ME values.
