Dog's body size and shape could indicate a greater bone tumor risk

New research has now confirmed that larger breeds, such as Rottweiler, Great Dane and Rhodesian Ridgeback, have a greater risk of osteosarcoma than smaller breeds, as well as showing that breeds with shorter skulls and legs have lower osteosarcoma risk. The findings could inform future breed health reforms as well as studies into the way tumours develop from normal bone.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/0wcyqC-vnFQ View the source article

Milk prebiotics are the cat's meow

If you haven't been the parent or caregiver of an infant in recent years, you'd be forgiven for missing the human milk oligosaccharide trend in infant formulas. These complex carbohydrate supplements mimic human breast milk and act like prebiotics, boosting beneficial microbes in babies' guts. Milk oligosaccharides aren't just for humans; all mammals make them. New research suggests milk oligosaccharides may be beneficial for cats and dogs when added to pet diets.http://feeds.feedburner.com/~r/s

Paw hygiene no reason to ban assistance dogs from hospitals

According to a UN-agreement, assistance dogs like guide dogs, signal dogs and medical response dogs are welcome in hospitals and other public places. However, in practice, they are regularly refused entry. Hygiene reasons are often given as the main argument for this. Research now shows that the paws of assistance dogs are cleaner than the shoe soles of their users, and thus, paw hygiene is no reason to ban assistance dogs from hospitals.http://feeds.feedburner.com/~r/sciencedaily/plants_animals

A new blindness gene uncovered in a canine study

A study has uncovered a mutation in the IFT122 gene in blind dogs. The gene defect now discovered results in the progressive destruction of photoreceptor cells and retinal dystrophy. IFT122 is a new candidate also for retinal dystrophy in humans. A gene test in support of breeding and diagnostics has been developed based on the finding.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/PH-C4_O-zhU View the source article

Wolf social group dynamics matter for infectious disease spread, models suggest

By modeling wolves in Yellowstone National Park, researchers have discovered that how a population is organized into social groups affects the spread of infectious diseases within the population. The findings may be applicable to any social species and could be useful in the protection of endangered species that suffer from disease invasion.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/moCGUBjBqbs View the source article

Detection dogs help generate important data for research and conservation

It is often difficult to find out exactly where the individual species can be found and how their populations are developing. According to a new overview, specially trained detection dogs can be indispensable in such cases. With the help of these dogs, the species sought can usually be found faster and more effectively than with other methods.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/mLxDKMChjr0 View the source article

How did dogs get to the Americas? An ancient bone fragment holds clues

Researchers analyzed the dog's mitochondrial genome, and concluded that the animal belonged to a lineage of dogs whose evolutionary history diverged from that of Siberian dogs as early as 16,700 years ago. The timing of that split coincides with a period when humans may have been migrating into North America along a coastal route that included Southeast Alaska.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/N2i3DTAOzsU View the source article

New features of a gene defect that affects muzzle length and caudal vertebrae in dogs

A recent genetic study provides new information on the occurrence of a DVL2 gene defect associated with a screw tail and its relevance to canine constitution and health. The variant was found in several Bulldog and Pit Bull type breeds, and it was shown to result in caudal vertebral anomalies and shortening of the muzzle. The DLV2 variant may also affect the development of the heart.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/gFGqT4IFfvY View the source article

Wolves prefer to feed on the wild side

When there is a choice, wolves in Mongolia prefer to feed on wild animals rather than grazing livestock. Previous studies had shown that the diet of wolves in inland Central Asia consists mainly of grazing livestock, which could lead to increasing conflict between nomadic livestock herders and wild predatory animals like wolves.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/Bnl_59N4xto View the source article

Toward a disease-sniffing device that rivals a dog's nose

A new system can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog's nose. Researchers coupled this to a machine-learning process that can identify the distinctive characteristics of the disease-bearing samples.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/58oOFy7Hz5I View the source article

Researchers uncover hidden hunting tactics of wolves in Minnesota's Northwoods

Researchers show that wolves have evolved ambush hunting tactics specifically tailored for catching and killing beavers. The study challenges the classic concept that wolves are solely cursorial predators. Instead, wolf-hunting strategies appear highly flexible, and they are able to switch between hunting modes (cursorial and ambush hunting) depending on their prey.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/m-CrhO7C7yk View the source article

Challenges of animal ownership during the pandemic should be considered alongside the potential benefits, study shows

Animal owners frequently report concerns and worries relating to caring for their animal during the pandemic, new research suggests. The study also revealed owners had increased their appreciation of their animals during the first lockdown phase. The notion that people 'could not live without' their animals and that they were a 'godsend' or a 'lifeline' in the pandemic was frequently expressed.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/b0QOcB1hK3g View the source article

New stem cell therapy in dogs -- a breakthrough in veterinary medicine

Scientists have developed a novel method to induce stem cell generation from the blood samples of dogs. Through this technique, the scientists hope to advance regenerative therapies in veterinary medicine. This would mean that, in the near future, veterinarians might be able to reverse conditions in dogs that were previously thought incurable.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/p2Ni8rD2r3A View the source article

Women influenced coevolution of dogs and humans

A cross-cultural analysis found several factors may have played a role in building the relationship between humans and dogs, including temperature, hunting and surprisingly - gender. The analysis used ethnographic information from 144 traditional, subsistence-level societies from all over the globe. People were more likely to regard dogs as a type of person if the dogs had a special relationship with women -- such as having names and being treated as family.http://feeds.feedburner.com/~r/science
