If happening after physical activity Iwould first think of low blood sugar -- hypogylcemia. Do you have Nutrical on hand? Rub a little of that on his gums when this happens to see if it improves. This is a potentially dangerous problem and not to be taken lightly. If you do not have Nutrical, you can use a little corn syrup, rubbed on his gums same way. Make sure he eats regularly. I would really be watchful when he is active, especially. Do not leave the little one alone, until you get this problem identified for sure.
Google hypoglycemia in puppies and see if you recnogize the symptoms. |
