Can be caused by

*Absolute deficiency of insulin due to [[Endocrine Pancreas - Pathology#Degenerative pathology|degenerative changes]] in beta cells (Miniature poodles, Dachsunds,Terriers seem to be predisposed)

*Absolute deficiency of insulin due to [[Pancreas, Endocrine - Degenerative Pathology|degenerative changes]] in beta cells (Miniature poodles, Dachsunds,Terriers seem to be predisposed)

*Antagonism of insulin by hormones from the adrenal and thyroid glands, anterior pituitary causing high levels of blood glucose (e.g. progesterone may initiate postoestrus DM in the bitch, hyperadrenocorticism)
