MacInnes, known as Puck, is a grinder â sailingâs equivalent of a football lineman. With their brawn, he and other grinders operate hand-powered winches that raise and trim the sails, move the boom and do other tasks that require brute strength. But MacInnes has fallen victim to legal maneuvering and technology.
A study of a cross section of puppies showed that at 6 weeks, only 25 percent of puppies vaccinated were effectively immunized. At 9 weeks, that increased to 40 percent. At 16 weeks, 60 percent responded to the vaccination, and at 18 weeks, that number increased to 95 percent.
Soon after you bring your puppy home (preferably no younger than eight weeks of age), itâs time to start your socialization training program. Most puppies will not get all their shots until they are 15 to 16 weeks of age. Some breeders and veterinarians recommend an even more extended schedule.
