Young puppies are highly vunerable to certain infectious diseases and should be vaccinated against them the moment they're old enough to construct immunity. These diseases are distemper, infectious hepatitis, parvovirus, parainfluenza, and rabies. Leptospirosis, giardia, coronavirus, bordetella, bronchiseptica, and Lyme disease vaccinations are optional, depending on the occurrence of those diseases in your area and your dog's individual risk factors.
The American Animal Hospital Association (AAHA) has drafted guidelines categorizing vaccines as core, noncore, or otherwise recommended.
While the following tips suggest that puppies as young as 6 weeks might be vaccinated, most veterinarians and breeders hold back until 7 or 8 weeks of age. Also, vaccine recommendations state that many vaccines don't need boosters beyond 12 weeks of age, but veterinarians, particularly in endemic disease areas, may perform a final puppy vaccine at about 16 weeks.
A recombinant distemper vaccine has become available and, ideally, dogs will get either an MLV or perhaps a recombinant version of distemper vaccine. The first distemper shot should be given soon after weaning and before a puppy is positioned in his new home and it is subjected to other dogs. Some veterinarians recommend vaccinating puppies at 5 to 6 weeks of age, utilizing a combination canine distemper-measles-parainfluenza vaccine.
The explanation for combining distemper and measles vaccines is that a higher area of 6- week-old puppies don't get a reasonable response in the distemper vaccine alone due to maternal antibodies that neutralize the distemper antigen. The measles virus, quite like the distemper virus, can overcome maternal antibody interference and induce partial distemper protection.
Alternatively, if maternal antibodies have actually disappeared in the 6-week-old puppy, the distemper portion of the vaccine will induce complete protection.
The distemper-measles vaccine should be used only once, for that first vaccination, in support of in puppies. The newer recombinant distemper vaccine appears to overcome maternal antibodies and it is now thought to be a better option compared to distemper-measles combination.
Postvaccination encephalitis has occasionally occurred when an MLV distemper vaccine has been utilized in in conjunction with a parvovirus vaccine in pups younger than 6 to 8 weeks of age. Therefore, parvovirus vaccine shouldn't be given combined with the first distemper vaccination in very young puppies. The recombinant distemper vaccine is not likely to cause encephalitis, and it is therefore suitable for young puppies.
Puppies younger than 8 to 9 weeks of age should be revaccinated every a month until they're 16 weeks of age. Current recommendations will be to revaccinate at 1 year of age or in annually in the last vaccination, and then every 3 years. This time around period might be extended with future research data on amount of immunity.
