I am so sorry to hear that your Pom is unwell!
I am concerned because he is taking in so little water, and no calories. Because he is small, he may have hypoglycemia (low blood sugar). I would like you to go right away and treat him for that by rubbing a 1/2 teaspoon of honey, karo syrup, corn syrup or pancake syrup on his gums, or let him lick it off your fingers if he will do that.
Please go do that now, and then come back and we can talk more!
No, don't bother with the honey now! He should have enough calories in there that I am no longer worried about low blood sugar!
Please let me know if he does vomit, or still cannot pass a bowel movement. I will be here to help!
That sounds good! I will be here for the next 1/2 hour, and then have appointments for 2 hours. Then I will be back!
