Abstract

In dogs, the phase from mating to the end of weaning lasts about 120 days and encompasses many aspects that, interacting, contribute to increase the allostatic load. The coat and claws, useful for long‐term change assessments, have the advantage of being collectable without invasiveness. In the present study, the Cortisol (C) and Dehydroepiandrosterone‐sulfate (DHEA‐S) concentration monthly changes in the coat and claws were studied in female dogs from mating to the end of weaning to assess Hypothalamic–Pituitary–Adrenal (HPA) axis activation during pregnancy and the post‐partum period. The results from 15 Dobermann Pinscher female dogs showed a trend of increase of the coat C from mating to 60 days post‐partum, with significant changes between mating and parturition‐60 days post‐partum (p < 0.01) and between the 30‐day pregnancy diagnosis (PD) and 30–60 days post‐partum (p < 0.05). The claws C trend showed significant increases between mating and 30–60 days post‐partum (p < 0.05) and between the PD and 60 days post‐partum (p < 0.01). DHEA‐S in both matrices showed non‐significant changes. The results suggest that maternity could play a pivotal role in the HPA axis activation, with a subsequent chronic secretion of C determining an increase in the allostatic load in the mothers. Neither maternal parity nor litter size played a significant role in the accumulation of C and DHEA‐S in both matrices.
