Any vet, even a dog/cat one will carry SMZ-TMP liquid( script only I believe ). It will knock cocci out over the course of a week and its only once daily. Tell them its for a baby goat with cocci and they'll let you buy it without bringing the goat in. Time is of the essence here as the goat can also be severely stunted and non thrifty. Cocci can cause a lifetime of problems if not treated quickly.
