However, in most instances, a difference of a few days is unlikely to have a negative effect on immune response. 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.
The normal fasting value for blood glucose in dogs is between 75 and 120 mg per deciliter. The renal threshold for glucose is 180 mg per deciliter, according to the Merck Veterinary Manual. This means that once the blood glucose levels are over 180 mg per deciliter, the excess glucose is passed in the urine.
