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

Many new college students report pet separation anxiety

A survey of a sample of new first-year college students leaving pets at home and found that 75% experienced some level of pet separation anxiety -- with one in four reporting moderate to severe symptoms. The students who had higher anxiety tended to be those who treated their pets more like people, identifying them as friends, sleeping in the same room and generally spending a lot of time with them. Students who had dogs at home also tended to report more attachment to their pets -- and more sep

Cat bacteria treats mouse skin infection, may help you and your pets as well

Researchers identify a strain of bacteria on healthy cats that produces antibiotics against severe skin infections. The findings may soon lead to new bacteriotherapies for humans and their pets, wherein cat bacteria is applied via topical cream or spray.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/hcAJTiqRHz0View the source article

Man's best friend could be a jaguar's next meal: A case study from the Mexican Caribbean

Events of jaguars predating on and attacking dogs are poorly documented throughout the Americas. Researchers from Mexico and Germany report in detail jaguar attacks on 20 dogs at a tourist site in the Mexican Caribbean. In addition, they describe an initiative proposed by locals as well as national and international NGOs to prevent human-jaguar conflicts due to pet predation.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/YMxp97HEvfUView the source article
