The article discusses a study where the thickness of the caudal pole of both adrenal glands were measured in 266 dogs with non-adrenal gland illness and compared based on the dogs' age, sex and body weight. The main outcome of the study noted that adrenal size in dogs with non-adrenal gland illness varies with body weight, age and sex and suggests that these variables should be considered when establishing normal values and evaluating adrenal glands.
