Yes. I have had this problem over the years. My little Angel Baby had this. I had the nutri-cal on hand, honey. Just a few little lickings, a couple 'finger lickings' of water and rest. Then when they come out of it, give a little food. Not too much of anything.
This makes me smile, thinking of Angel Baby who passed a year ago. I always make myself a vanilla latte in the morning and she would be waiting for her 'sugar sugar'. This was a couple fingers of the foam on top. Gave her a little boost, before feeding, while I showered. Ahhhh the memories of our past Yorkie babies!
