2-17-2013 New rat poison containing bromethalin is VERY dangerous to dogs, cats, and kids. (Submitted by by Steve Dobbins):
See the below link about this new rat poisons' main ingredient, bromethalin.
If my math and weight conversions serve me correctly:
My 90 pound German shepherd would be about 41 kg (2.2 lb/kg ).
So his median lethal dose would be 97 to 149 mg ! (at 2.38 to 3.65 mg/kg)
For those of you who might have difficulty grasping how small an amount this is:
When you mail a letter, your first class postage limits you to one ounce before additional postage is required.
(roughly equal to a large envelope plus 5 sheets of paper, the fifth or sixth sheet puts you over, depending on the paper)
One ounce is about 28.4 grams.
One milligram (mg) equals 1/1000 of a gram.
So his median lethal dose would be about 0.10 to 0.15 grams !!!
Or 0.0034 to 0.0052 ounces !!!
The following information is second hand. Apparently a Samoyed was poisoned in Denver while at the 4 day show cluster in Denver.
The Samoyed has already died from the poisoning. (This information is being put out and that show cluster is not even over)
The source of the poisoning may have been rat poisoning being placed under the beds at some hotels.
