A recent survey of 178 dogs in 10 states found that two-thirds consume higher-than-recommended levels of heavy metals in their drinking water. The study highlights the need for further research on the long-term health effects of these exposures, particularly in rural areas where private wells are common.
Researchers found that short-nosed dogs are calmer and less reactive, but this benefit is often masked by lack of training. Consistent training is crucial for their good traits to shine through.
A new study led by Texas A&M University found that popular sporting group breeds are more likely to be motivated by food, while owners in urban environments and with multiple dogs are also at risk.
