Dogs can be 'early-warning systems' for toxic chemical exposure at home

[FfFfFfFF 58,131]

More than 10,000 years of domestication have made dogs strikingly similar to humans, from their ability to read facial our expressions to our closely related genomes. Now, a new study reveals that dogs and humans carry the same toxic chemicals in their bodies—a discovery that could possibly improve human health.

Using silicone wristbands and collars—a relatively new technology for detecting chemical exposure—the team found remarkable similarities between dogs and their owners’ chemical loads, according to the study, published recently in the journal Environmental Science and Technology.

These results are encouraging, says study leader Catherine Wise, because they show dogs can act as early-warning systems for human health, providing valuable clues about the detrimental effects of these exposures. 

Wise adds that her research is particularly relevant now, due to the coronavirus pandemic.

“When most of us are stuck at home with our dogs a lot longer,” she says, the importance of “our shared environment has never been so great as it is today.”
