“…The aim of the study 1 was to evaluate the extent of variation of salivary cortisol in dogs in a routine context and not stimulated for physical or psychological activities. For this reason, we asked the owners to collect the saliva on day 1 (D1), after day 2 (D3) and day 4 (D5) in three specific times of the day, in part following the sampling schedule adopted in a previous study (Sandri et al 2015). Present results did not confirm the data obtained in the former study, which indicated a significant decrease of salivary cortisol in the evening sample.…”

“…In our study, the mean concentrations measured were not significantly different and numerically very similar, being 1.90 ± 1.59 ng/mL at MO, 2.20 ± 1.84 ng/mL at MD and 1.72 ± 1.88 ng/mL at EV. According to present and previous data (Giannetto et al 2014;Glenk et al 2014;Sandri et al 2015), the late evening sample (EV) was considered appropriate as a baseline value. This sampling time was also the closest to the T1 sampling moment and this time was adopted in the study 2 as T0 value.…”

“…In veterinary medicine, dog saliva has mostly been studied for cortisol determination, which varies with breed size, (where large dogs have lower salivary cortisol), between intact and castrated/neutered individuals, and with circadian rhythm . However, more recently, dog saliva has been used to measure C‐reactive protein and adiponectin for non‐invasive monitoring of systemic inflammation.…”

Saliva is a complex multifunctional fluid that bathes the oral cavity to assist in soft and hard tissue maintenance, lubrication, buffering, defense against microbes, and initiating digestion of foods. It has been extensively characterized in humans but its protein composition in dogs remains poorly characterized, yet saliva composition could explain (patho) physiological differences between individuals, breeds and with humans. This pilot discovery study aimed to characterize canine saliva from two breeds, Labrador retrievers and Beagles, and to compare this with human saliva using quantitative mass spectrometry. The analysis demonstrated considerable inter‐individual variation and difference between breeds; however these were small in comparison to the differences between species. Functional mapping suggested roles of detected proteins similar to those found in human saliva with the exception of the initiation of digestion as salivary amylase was lacking or at very low abundance in canine saliva samples. Many potential anti‐microbial proteins were detected agreeing with the notion that the oral cavity is under continuous microbial challenge.

“…The feces were collected after evacuation from the ground using sterile gloves and were placed in 50 mL sterile tubes and immediately frozen at −20 • C until analysis. Salivary samples were collected with SalivaBio swabs (Salimetrics, LLC 101 Innovation Boulevard, State College, PA, US) following the procedure previously described [14]. After sampling, the swabs were introduced into tubes specifically designed to avoid cortisol sequestration (Salivette; no.…”

Several studies on the interaction between gut microbiota and diets, including prebiotics, have been reported in dogs, but no data are available about the effects of dietary administration of grape proanthocyanidins. In the study, 24 healthy adult dogs of different breeds were recruited and divided in 3 groups of 8 subjects each. A group was fed with a control diet (D0), whilst the others were supplemented with 1 (D1) or 3 (D3) mg/kg live weight of grape proanthocyanidins. Samples of feces were collected at the beginning and after 14 and 28 days for microbiota, short chain fatty acid, and lactic acid analysis. Serotonin and cortisol were measured in saliva, collected at the beginning of the study and after 28 days. A significantly higher abundance (p < 0.01) of Enterococcus and Adlercreutzia were observed in D0, whilst Escherichia and Eubacterium were higher in D1. Fusobacterium and Phascolarctobacterium were higher (p < 0.01) in D3. Salivary serotonin increased (p < 0.01) at T28 for D1 and D3 groups but cortisol did not vary. Proanthocyanidins administration influenced the fecal microbiota and neuroendocrine response of dogs, but a high variability of taxa was observed, suggesting a uniqueness and stability of fecal microbiota related to the individual.
