Information sourcing by dog owners in the UK: Resource selection and perceptions of knowledge.

Background: Dogs are a popular pet in the UK. Information resources utilised by dog owners can influence welfare at acquisition and throughout a dog's lifetime. This study determined where UK dog owners source information, and how perceptions relating to pedigree dog breeding and health may influence this process.

The dog as a sentinel species for environmental effects on human fertility.

Despite the vast body of evidence that environmental toxicants adversely affect reproductive development and function across species, demonstrating true cause and effect in the human remains a challenge. Human meta-analytical data, showing a temporal decline in male sperm quality, are paralleled by a single laboratory study showing a similar 26-year decline in the dog, which shares the same environment. These data are indicative of a common cause.
