Newmanâs Own Socialism? Mark Engler &squarf; September 22, 2010 I recently started shopping at a grocery store that is conveniently located near where I live, but that unfortunately doesnât have a lot of organic food options.
Some owners may be surprised to know that a female Boxer can enter heat relatively early. Boxer dogs typically enter the first heat between the ages of 6 months old and 1 year old. However, some may have it as early as 4 months or as late as 15 months old. If your un-spayed female does not have her first heat by the age of 2 years old, you'll want to alert the veterinarian. Since the heat cycle will occur when a Boxer is still a puppy, this means that he is able to become pregnant at that young age.
Small breed dogs typically start having estrus (heat) cycles earlier, at 4-6 months of age, and large breeds typically start later, at 12 to 24 months of age. The estrus cycles vary between each individual dog, average of 7 to 10 days. Some dogs as few as 2 days, some dogs cycle as long as 21 days.*.
