Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 2 months and 9 days old | 1.5 lbs

I just took my dog to the vet and they told me he has hypoglycemia and they sent me home with special high calorie food and told me to feed my puppy more because he was severely dehydrated and lethargic. He was very week and they gave fluid and karo syrup and he was better but at home he drank a lot of water no food and threw up 4-7 times. He's stumbling again and is starting to become weak. Unsure what to do pls help how do I get him to eat or do I take away his water?(Male 10 wks maltipoo)

Hypoglycemia is a big problem in small breed puppies. At 10 weeks old I would worried about that and also it could be that he has a liver problem (shunt) or a cardiac issue. Teddy may need more testing to figure out what is going on. An ultrasound may be taken of the abdomen to try and identify a pancreatic, liver or other type of tumor that could cause hypoglycemia. Puppies and adult dogs that appear to be in a stupor or coma during a hypoglycemic attack should immediately be given sugar water or an oral concentrated solution of glucose, such as corn (Karo) syrup or Nutri-Cal. Rub it directly on his gums. The sugar will be absorbed directly through the tissue into the bloodstream. You should add two tablespoons Karo syrup to your puppy’s water for all day sipping. Be sure to dump out and add fresh each day or the sugar water could grow bacteria. Schedule several meals every day. Toy breed adults and any young puppy have trouble eating enough food at one setting. So a small meal several times a day helps keep the blood sugar levels normal. I hope this helps. You really need to keep in contact with your vet about Teddy's symptoms. Best wishes.
