I know there is debate over the PP, but I've decided to follow my vet's recommendation and do it. I started today. I've read in other threads that one of the side effects could be signs of colic. My question, when can those signs appear? First day? Day 3? Two weeks? Any and all days? Wondering if I need to stick around the farm to keep a watchful eye. Also, when do they start shedding? Is that when colic signs might appear? And finally, is there a better part of the day to deworm?
