Researchers found that companion dogs, but not pigs, would show their owners the location of a food reward out-of-reach. This suggests that directing humans' attention to interesting locations may not be a universal ability among domestic animals. Dogs and other visually communicative species were more likely to use this behavior.
Steaming hay kills harmful microorganisms, but damages proteins making them less digestible for horses. This can lead to impaired muscle development and nutrient deficiencies, affecting growth and coat health. Horses can be enriched with protein-rich feedstuffs to mitigate this risk.

Cats spent more time at the tray and made more first choices to eat from it than the puzzle, suggesting a preference for easy access to food.
A new model calculates maximum running speeds for animals of any size, revealing that medium-sized animals achieve top speed due to their body shape and leg structure. Larger or heavier animals are limited by the weight and stiffness of their bones, resulting in lower top speeds.

The findings, based on underwater excavations, provide new insights into the region's moral code and power structure.
A new paper suggests that diseases can be more lethal in new hosts with larger evolutionary jumps between species. This research uses data from the World Organisation for Animal Health to track diseases across domesticated mammals and their outcomes.
A study by Radboud University ecologist Luca Santini found that mammals living in urban environments produce more young, which is likely due to high mortality rates. Different groups of mammals use various strategies to adapt, such as producing larger litters, having brains and bodies better suited for their environment.
A team of researchers found that animals switch to more stable gaits during speed-related transitions to minimize unstable dynamic states and reduce the risk of tripping or falling. The study, which examined nine animal models across various species, suggests that gait transitions prioritize stability over energy savings.
