  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.
  4. 2P–values for faecal pH was determined for seven dogs (CD1 vs. HMB) and five dogs (CD2 vs. HMB), due to missing values.
  5. *Considered statistically significant; ** Considered a trend
