Enzymatic blood activity at different stages of the dog’s life. Comparison of the means (red line) of (A) ALT, (B) LDH, and (C) ALP between groups of clinically healthy dogs of different ages: group I (n = 35, 4–8 wk), group II (n = 48, 9–24 wk), group III (n = 21, 25–52 wk), and group IV (n = 71, > 52 wk). Horizontal blue dotted lines represent the RIs for adult dogs with a 90% CI (see Table 1). Means that do not share a letter are significantly different (p < 0.05)
