Oxidative stress has been associated with the development of many chronic and degenerative diseases in canines. The presence of antioxidants in food contributes to the reduction of the harmful effects of reactive oxygen species (ROS) and nitrogen (RNS). Polyphenols are a group of substances with high antioxidant activity and play an important role in the prevention of diseases. The aim of this study was to evaluate the relationship between the composition, the antioxidant capacity and the polyphenol content of dog feeds from different commercial segments. Nineteen dog foods from four commercial segments: popular, economic, premium and super premium were randomly selected. Through a bromatological analysis the composition of each feed was evaluated. Total antioxidant capacity (TAC) and total phenolic content (TFC) were measured through the ABTS and Folin-Ciocalteu methods, respectively. A...

The study aimed to assess the efficacy of high-intensity interval-training (HIIT) compared to moderate-intensity continuous training (MICT) for 12 weeks on a treadmill on maximal aerobic potency, aerobic resistance, respiratory and heart rate at rest, left ventricle structure and function in dogs. The study design was a blinded controlled clinical trial. Thirty untrained dogs between 12 and 84 months were randomly distributed in the groups: HIIT (n=11), MICT (n=9); and control (n=10). Dogs with cardiovascular, neuromuscular, orthopaedic conditions, body condition score over 7, or any abnormalities that impaired exercise performance were excluded. Before and after the programme, dogs performed an incremental exercise test to determine the maximal velocity (Vmax) and velocity at lactate threshold (VLT). Respiratory and heart rates and left ventricular chambers and systolic function at rest...
