I've got 10 lab puppies, who are 6 weeks old and I just got a quote from the vet... $660.00. I saw another question from a woman asking for information on how to give them their shots herself. I am going to do that myself. But am unsure as to where to buy the supplies from. I live in a small town in British Columbia, Canada. Does anyone now someplace on-line to purchase this medication, what exactly I should be buying (the names)?
