I didn't move his thread, but the answer is "sometimes". When a new member makes an off-topic post, they almost always receive a PM letting them know and explaining why the thread was moved. More senior members, who know the forum is kept strictly on-topic don't always receive a PM. Honestly, they should already know better.
With regards to the dog getting sick, that would be terrible. Hopefully Taylo has asked the question elsewhere too, where it would be more appropriate.
