Hello, I understand that you are concerned about Ratimor causing the death of a small dog.
Ratimor is a rodenticide that contains the anticoagulant bromadialone but it is at a fairly low concentration.
The maximum tolerated oral dosage of bromadiolone is 10mg/kg. For a 10 kg (22 pound) dog, this corresponds to 100 mg of pure Bromadiolone. That would be 2 kilograms of bait at the dosage of 0.005%. At doses of 15 mg/kg and higher, hemorrhages would begin to appear on the third day after exposure which would be fatal unless we administer an intravenous injection of Vitamin K1 at a dose of 5 mg/kg of body weight.
So while it is possible that Ratimor could be deadly in a small dog they would have to eat a significant amount of the toxin to cause bleeding and death.
Please let me know if you have any further questions.
how much is a significant amount
