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.

Correcting night blindness in dogs

Researchers have developed a gene therapy that restores dim-light vision in dogs with a congenital form of night blindness, offering hope for treating a similar condition in people. View the source article

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

Genomic effects of inbreeding on Scandinavian wolves

Researchers have been exploring the genetic origins of the Scandinavian grey wolf population, which was founded by only three immigrating wolves. The scientists show that, after five generations of inbreeding, between 10 and 25 per cent of the original genetic variation has been eliminated. View the source article

Advanced prostate cancer antibody drug shows success in pet dogs

Mice are typically used as models in advanced prostate cancer research, but the profound differences between them and humans has long bedeviled the translation of findings from the animal to success in people. Dogs however are the only other animal that suffers from a significant incidence of prostate cancer, and researchers are finding them much more enlightening subjects in identification of drugs that show promise for human patients.

What is your dog’s lifespan? You might be surprised

The Dog Aging Project, founded in 2018, is by far the most ambitious project tackling the question of canine longevity, enrolling and studying tens of thousands of dogs of all sizes, breeds and backgrounds to develop a thorough understanding of canine aging. Their open-source dataset will give veterinarians and scientists the tools to assess how well a specific dog is aging and will set the stage for further research into healthy aging -- in both dogs and people. One of their most intriguing ave

Gene mutation that makes dogs small existed in ancient wolves

Popular belief has been that small dogs, such as Pomeranians and Chihuahuas, exist because once dogs were domesticated, humans wanted small, cute companions. But researchers now identify a genetic mutation in a growth hormone-regulating gene that corresponds to small body size in dogs that was present in wolves over 50,000 years ago, long before domestication.

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

New method gives rapid, objective insight into how cells are changed by disease

A new 'image analysis pipeline' is giving scientists rapid new insight into how disease or injury have changed the body, down to the individual cell. It's called TDAExplore, which takes the detailed imaging provided by microscopy, pairs it with a hot area of mathematics called topology, which provides insight on how things are arranged, and the analytical power of artificial intelligence to give, for example, a new perspective on changes in a cell resulting from ALS and where in the cell they ha
