How can a diabetic dog not stand up after eating metformin?

I wonder who diagnosed it. What are the diagnostic criteria for dog bedwetting patients? Let's talk about metformin first. Metformin is an insulin sensitizer, which increases the sensitivity of insulin, makes it work better, and converts glucose into energy needed by the body. This medicine will not cause hypoglycemia or gain weight (maybe lose weight), but it has gastrointestinal reaction (the most common) and fatigue, which may be caused by these side effects.
