Introduction
Stress is a response of the body to physical or psychological environmental stressors. Cortisol level
in blood serum is an indicator of stress, but the blood collection can cause unpleasant conditions and rise
of this hormone. Therefore, less invasive methods are searched to determine stress hormone level, for example, by measuring it in saliva.
Objectives
The aim of the study is to find out the changes of stress hormone in blood and saliva in home and experimental dogs in simulated short-term stress conditions.
Methods
The study included six clinically healthy experimental beagle dogs and six home American Staffordshire terriers. The animals were let into a fenced area to adapt. Loud drum sounds were used as a stressor. Blood serum samples were taken for sodium, potassium, glucose and cortisol level determination, saliva samples – for cortisol determination.

Introduction
Canine Monocytic Ehrlichiosis (CME) is a prevalent systemic disease worldwide that causes lesions due to direct agent injury and secondary autoimmune lesions in the dog. It is known the occurence of myocarditis in this cases.
Objectives
The present study analyzed the clinical, haematological, biochemistry and analysis of cardiac biomarkes data, Creatinokinase-MB (CKMB), Cardiac Troponina I (cTNI) and N-terminal pro B-type natriuretic peptide (NT- proBNP) in infected dogs on the chronic phase of CME.
Methods
It was used 20 naturally infected dogs on the chronic phase of CME at the inicial attendance (G1) and a follow- up of 28 days (G2) was made. This data was compared with a control group of ten healthy animals.
Results
Eight of the 20 dogs (40%) died after 28 day
monitoring. Anorexia, emesis, fatigue, heart murmur, hypoalbuminemia, heart murmurs and raise of Alanina Aminotranferase (ALT) and Alkaline Phosphatase (AP) were common signs encountered. Fatigue was statistic preditor of mortality. The mean concentration of cTNI and CKMB was significant (0.24 ng / mL ± 0.5; 229 ± 205 IU / mL) compared to the control group (0.042 ± 0.07 ng
/ mL;126 ± 46 . 12 IU / mL). No differences were found between the concentration of NT-proBNP on G1 (135.46 ± 29.7) and G2 (138.28 ± 19.77).

Results
Cortisol level in the blood and saliva showed different increase and decrease rate both in home and experimental dogs. Blood sodium, potassium and glucose measurements did not show any significant changes.
Conclusions
Therefore, the authors can conclude that each animal responds to a stressful situation with different hormonal activity. Cortisol level in saliva and blood is released with different speed and is not an objective indicator of acute stress.
