Roof rat problem here in winter. Before Dixie came to live here the whole patio/dog run area was open to the dogs. Put D-Con in the crawl space...got to thinking OMG...what if a rat died and the dogs ate it??? since their "route" was where the dogs had acess. Called the 800 number. Was told that since the poison caused the rats to bleed out it would take 10 eaten per pound of dog weight for there to be a problem. Since my kids are/were 70 to close to 90 pounds I was told not to worry. Since Dixie the rat "route" is fenced off.
