INVESTIGATIONS INTO HYPERLIPIDEMIA AND ITS POSSIBLE ...

might affect lipid metabolism (hypothyroidism, pancreatitis, pregnancy). Thus, 16 dogs
completed the study.
The 16 dogs that completed the study had a median BCS of 5 (range: 4 to 6) and
a median age of 8.5 years (range: 6.7 to 11.9 years). Eleven dogs were female (all
spayed) and 5 dogs were male (all castrated).
Group 2 consisted of 28 Miniature Schnauzers that had a median BCS of 5
(range: 4 to 6) and a median age of 9.1 years (range: 7.1 to 12.2 years). Fourteen dogs
were female (8 spayed) and 14 dogs were male (5 castrated).
Serum triglyceride, cholesterol, and Spec cPL concentrations in Group 1
Analysis using the Friedman’s test (repeated measures non-parametric 1-way
ANOVA) showed that serum triglyceride concentrations before the diet change (median
of sample 1: 480 mg/dL; median for sample 2: 493 mg/dL) were significantly higher
than after the diet change (median of sample 3: 177 mg/dL; median for sample 4: 168
mg/dL; P=0.0001; Figure 16). Dunn’s post-test indicated that there were no significant
differences between samples 1 and 2 (i.e., while dogs were on their original diets) or
between sample 3 and 4 (i.e., while dogs were on the study diet). There were significant
differences between samples before and after the diet change (P500 mg/dL in Group 1
