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

Scent dogs detect coronavirus reliably from skin swabs

A recent study confirmed that scent detection dogs can be taught to identify individuals with a coronavirus infection from skin swabs. In the experimental set-up at Finland's Helsinki-Vantaa International Airport, the accuracy of the dogs in identifying the samples was 92 percent. 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.

Cortisol in shelter dog hair shows signs of stress

Despite the good care, a shelter can be a stressful environment for dogs. Researchers investigated if the amount of the hormone cortisol in hair indicates the levels of stress that dogs experience before, during and after their stay in the shelter. View the source article

Dried avocado meal, a novel fiber source to be added to commercial dog food

Thanks to avocados' rise to superfood stardom, there are now more avocado-derived products in the supply chain than ever. In a unique study, researchers looked at the possibility of using avocado meal -- the ground, dried, and defatted pulp, seed, and skin left over after avocado oil processing -- as a fiber source in dry dog food.

Researchers discover genetic cause of sometimes deadly esophageal disorder in dogs

German shepherds are predisposed to congenital idiopathic megaesophagus (CIM), an inherited disorder where a puppy develops an enlarged esophagus that fails to move food into their stomachs. Puppies with the condition regurgitate their food and fail to thrive, often leading to euthanasia. Researchers have now developed a genetic test for the disease that German shepherd dog breeders can use to reduce the risk that puppies in future litters will develop the disease.

COVID in a cat

A study has confirmed what is believed to be the first published account of the delta variant of SARS-CoV-2 in a house cat. The viral sequence was a close match to strains circulating in the Philadelphia area at the same time, underscoring the virus's ability to jump from one species to another without acquiring significant mutations.

Core strength could help dogs avoid knee injuries

Agility dogs lacking core strength from routine physical exercise may be more susceptible to one of the most common canine knee injuries, a cranial cruciate ligament rupture, which is similar to an ACL tear in humans. According to a research survey documenting activity and injury odds of more than 1,200 agility dogs, just about any physical exercise seems to lower the risk of rupturing the ligament, but some exercises seem to increase the risk. In addition, the size and shape of the dog -- and t

Decline of vultures and rise of dogs carries disease risks

This is a story about vultures, feral dogs, rabies -- and piles of rotting animal carcasses. Buckle up. But in the end, it's about the power of conservation to keep ecosystems, even urban ecosystems, in balance, benefiting the people who live there. View the source article
