Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 50 lbs
My pet is 2 years old and weighs 50 pounds she ate less than half a block of tomcat rat poison. I tried using hydrogen peroxide to make her throw it up however that did not work. It’s been about 10 hours and she’s seems fine. From what I’ve read it doesn’t seem like she ate enough to harm her but I’m really not sure and would like some advice

The fact she vomited it up clears about 60-70% of her stomach is the amount digested and absorbed is significantly reduced. However, there are two types of rat poison, one is an anti coagulatant and another affects the central nervous system. The first is responsive to vitamin k, the other has no antidote.
Tom cat brand is typically the neurological form of poison. Vitamin I will not hurt but it won’t help if that is the case. You need to watch for twitching or seizures and weakness over the next week.
