Thanks and no, I'm not his or any type of breeder. He actually came from a very irresponsible breeder and came to us when he was way too young to be taken away from him mom.
The vet said rectal prolapse does happen to puppies sometimes and there could be varies causes but heart worms were usually the most common. And so I've started him on his heart worm meds. (The reason I haven't done so is b/c the original vet said not to while he's taking current meds for his prolapse.)
He seems to be doing fine right now and just being a brat.
The ER vet also supplied some pain meds so he'll be on that for the next 3 days.
I'd post a picture of him but I haven't read the direction as to how yet but I will soon. He's really adorable and the family just loves him.
