My friend, you can do a lot of self learning over the internet using Google just like the rest of us, and you know what the best thing about it is? It is FREE and you can go on to learn more and more things, kay?
Just type words like "neuter dogs" ( or "glucose puppy sick") and you will get tons of info to read, including cautions, how to prepare your dog before the operation, how to take care of him immediately after surgery to make him comfortable, even see pics of what the surgeon does to the dog during neutering, the benefits of neutering, etc. etc. ... huhuhuhuuuuu!!!! Lipink, I give you 1 month and you will soon be the guru on this forum giving out answers to newbies ...
