Serum total immunoglobulin E (IgE) (a, b), ragweed (RW)-specific IgE (c, d) and immunoglobulin G (IgG) (e, f) levels in offspring, exposed to either RW or air (control), from non-allergic (a, c, e) or allergic (b, d, f) parents. After the collection of blood at 28 weeks of age, dogs were challenged by instillation with RW, and further blood samples were collected on day 1 (d1) and day 4 (d4) after challenge. *P < 0·05 versus control. #P < 0·05 versus non-allergic [one-way analysis of variance (anova) with Tukey multiple comparison post-test]. Linear trend post-test analysis using 12–28 week samples (†P < 0·05). Linear trend analysis for RW-specific IgE did not reach statistical significance (P = 0·08). All error bars are expressed as mean + standard error of the mean (SEM).
