There are meningococcal vaccines that help protect against five types (serogroups) of meningococcus bacteria, including the three types most common in the United States (serogroups B, C, and Y).

Small breed dogs typically start having estrus (heat) cycles earlier, at 4-6 months of age, while large breeds typically start later, at 9 to sometimes as late as 24 months of age. Estrus cycles can vary between each individual dog, an average of 6 to 12 days. Some cycles can last as few as 2 days, while others can last as long as 21 days.1 Female dogs cycle throughout their life and do not experience menopause (reproductive cycles ceasing with age), like human females do.
