I looked at some previous post on worming goats but couldn't find an age to start worming at. my goat is a 9 week old saanen alpine so how much to give? weigh her or should i use the girth weight method? use safeguard or ivermectin first? how often to alternate. when should the CDT shot be given and when should it be repeated? can i do it myself or should i go to the vet? sorry for all the questions but i would like to get a friend for my girl and want her to be all up to date and be able to get the new one up to date too
