Hypoglycaemia in the dog
The dwarf and toy breeds often show phases of hypoglycaemia (lack of sugar in the blood) before the age of six months. These breeds are very often extremely sensitive to stress, which could lead to hypoglycaemia by consumption of sugar reserves.
The dog shows great weakness and depression. Sometimes he is unable to stand on his feet. It shows convulsions, and often hypothermia. The dog must be infused to give him the glucose that is deficient. In adulthood, if the disorders have not disappeared, look for another cause of these symptoms.
