With the exception of rabies vaccine, ACIP allows a grace period of 4 days (i.e., vaccine doses administered up to 4 days before the recommended minimum interval or age can be counted as valid).
Blood Glucose in Dogs. Healthy dogs have normal blood glucose levels, which tend to range from 75 to 120 milligrams per deciliter of blood. Dogs that have levels of 80 milligrams per deciliter or lower are likely to develop hypoglycemia.
Edit. Normal blood glucose values for non-diabetic cats and dogs range from 80-150 as measured on a vet's glucometer.
