Overweight dogs respond well to high-protein, high-fiber diet

A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs' body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all decreased with weight loss. View the source article

Top predators could 'trap' themselves trying to adapt to climate change

Over a 30-year period, African wild dogs shifted their average birthing dates later by 22 days, an adaptation that allowed them to match the birth of new litters with the coolest temperatures in early winter. But as a result of this significant shift, fewer pups survived their most vulnerable period because temperatures during their critical post-birth 'denning period' increased over the same time period, threatening the population of this already endangered species. It is the first study to sho

Urgent action needed on English Bulldog breeding, experts say

English Bulldogs must be bred with more moderate physical features, experts say, as a new study reports that the breed is significantly less healthy than other dog breeds. English Bulldogs are at increased risk of breathing, eye, and skin conditions due to their extreme physical features, including shortened muzzles, folded skin, and a squat body, reports a recent article.

A large predator from the Pyrenees

A fossilized lower jaw has led an international team of palaeontologists to discover a new species of predator that once lived in Europe. These large predators belong to a group of carnivores colloquially known as 'bear dogs'. They could weigh around 320 kilograms, appeared 36 million years ago before becoming extinct around 7.5 million years ago. View the source article

Quantifying cognitive decline in dogs could help humans with Alzheimer's disease

Researchers have found that a suite of complimentary tests can quantify changes in dogs suspected of suffering from cognitive decline. The approach could not only aid owners in managing their elderly canine's care, but could also serve as a model for evaluating cognitive decline progression in -- and treatments for -- humans with Alzheimer's disease.
