  1. ♦Maximum and minimum values are provided in brackets.
  2. Abbreviations and explanation: The diet periods were as follows: CD1 for week 1 and 2, during which all dogs were acclimated to commercial dry food (CD; Felleskjøpet’s Labb adult), followed by incremental substitution of the CD diet with minced beef − LMB, low minced beef for week 3, MMB, moderate minced beef for week 4, and HMB, high minced beef for week 5 – and finally, CD2 for week 6 and 7, during which the dogs were reintroduced to the CD diet.
  3. 1Wilcoxon-matched sign rank test without correction for multiple comparisons. P-value for CD1 vs. HMB was determined for 9 dogs and P-value for CD2 vs. HMB was determined for 8 dogs.
