Here is the thing with rat poison, if it is good old decon(not a newer generation poison) and you saw or know the dog ate it, you made them vomit and you got them on vit K for 3 weeks 99.999% of them will be fine.
It is when you don't know they ate it, don't seek medical care thinking they seem fine that 2 weeks later you are in a world of hurt. I can't tell you the number of people I have argued with on the phone that they need to make the dog vomit and get them on vit K but they refused because the dog is fine(for now). If they don't want to follow advise why call?
Anyway, you are a great mom. You monitored your dogs enough to know what happened and took the appropriate steps to assure their well being. Accidents happen that's why they are accidents. It is how we respond to them that shows our character. HUGS
