I have a long coat chihuahua named Louie. He is just 10 weeks old an such a sweetheart. But he has a problem with low blood sugar. I took him to the vet because he had suddenly become sick overnight. He was perfecty fine and playful before bed and in the morning he could not lift his head. The vet said he was hypoglycemic and gave him a sugar solution and he perked up within a half hour. Now I give him the sugar every 3 hours and even have to wake him at night to give him some so he will not be so low in the morning. Does any one know if this is common in chihuahuas and will he grow out of at as he gets older?
