So do humans... DEET in bug spray, stimulants in Red Bull, a bazillion things in cigarettes, **** in Coke, crap in McDonald's, pills pills pills pills, mercury from the weekly sushi fix, fertilizers and pesticides on the lawns, pollutants from vehicles and in the atmosphere, I'd hazard a guess that we're just as polluted as Fido and Morris.
I am glad they're studying this. I do feel there is an overuse in chemicals that we can do without.
How about all the prescription drugs in our drinking water?
Animals pick up different things because they don't wear shoes and lick their feet. And then there are all the chemicals we deliberately inject into animals. That's why I don't feed raw, actually. I don't want my dogs eating tons of animal flesh that has been treated poorly, in every sense of the word.
