Chihuahua Blood Sugar Problems

Updated on December 22, 2016

What is Hypoglycemia in Chihuahuas?

Chihuahuas, like many small breeds, have trouble regulating their blood sugar. The first time my Chi suffered an episode of low sugar, I really did not know what was wrong. He was 7 months old, and had a pretty typical day. Then a short time after playing, he started walking like he was drunk. It was as though he had no control over his legs. He threw up foam and then basically fell over. I was beside myself how we could have been playing one minute and into this scene the next.

I have always had at least one dog in my life, and my Chihuahua, Norbit was my first small breed of dog and I was not savvy to the hypoglycemia thing. It was on a Sunday, so we wrapped Norbit up in a blanket and went to the emergency vet. They took one look and said my dog had been poisoned. I said that was really impossible, he literally spent zero time unattended. I knew for certain my dog hadn't chewed on anything but his toys. Then another vet tech on duty said, "He is in sugar shock". She had several Chihuahuas at home herself she had rescued and she said low blood sugar wasn't uncommon in small breeds.

She put some Karo syrup on a flat wooden stick and he just stared at it glassy-eyed like he had no idea how to lick. So she put roughly a teaspoon of the syrup in a syringe and while explaining I should never do this at home as he could choke, he gently pushed the syrup right down this throat. He was seriously right as rain in a very short time. It was extremely frightening however and I vowed to do my best that my dog never experienced this again by learning why it happened and what I needed to do to prevent it.

What Symptoms Will My Chihuahua Have?

In the case of my dog, his low blood sugar was caused by a play session that went on a little too long and too hard. Who can say no when a puppy keeps wanting to play? That was my mistake and I definitely learned from it.

I found from talking to my vet that a chihuahua with low blood sugar may :

  • Wobble when either standing or sitting.
  • If laying down your dog may have trouble lifting his head.
  • Your dog may have a blank stare with glassy eyes.
  • Often dogs in sugar shock tilt their heads to one side as if their head is very heavy on one side.
  • As the low blood sugar progresses, your dog may shake badly, drool and froth at the mouth.
  • Obvious signs of being disoriented.

Home Treatment of Hypoglycemia for Your Chihuahua

These tips for home treatment are only to get your Chihuahua up and about. Always follow up with your vetrinarian. It's important to make sure there are no other outstanding medical issues causing that may have the same symptoms as low blood sugar such as tumors, bacterial infections, pancreatic issues and other serious medical conditions.

Your goal here is to raise your dog's blood sugar so something sweet is in order. You can use honey, Karo syrup, or maple syrup. Also, I've used vanilla ice cream. As hypoglycemia can progress quickly and become life threatening for your pooch, it's important to act fast. Whatever method you choose to raise your dog's sugar level, don't just put honey in his mouth. He could choke. If he will lick it off your fingers, great. If not, you can rub honey, syrups or ice cream on your dog's gums. Be careful, disoriented dogs can bite. If your dog has passed into the severe stage of low blood sugar and is having focal seizures or unconscious, keep rubbing syrup on their gums on the way to the vet, it may be life saving for your pet. It doesn't take much.

On the few occasions my 10-lb chihuahua has gone into sugar shock, it's taken just a couple of teaspoons of honey to bring him around. After your dog becomes alert, he should eat as soon as possible so his blood sugar can become stable. You can give your dog regular food or treats, whatever you can get him interested in eating is fine. Add a little honey or ice cream to entice them to eat.

Last Word About Low Blood Sugar and Your Chihuahua

You can almost entirely avoid bouts of hypoglycemia by feeding your dog regularly and according to Dr. Greg Martinez DVM, since a lot of commercial dog foods are high in grain products, those foods actually set your dog up for low blood sugar. By switching to a low glycemic dog food, you can help your Chi maintain a more constant sugar level.

My vet advised me to feed my dog more than twice a day. So I just took his total amount of food and divided it up into smaller servings and if we do happen to have a play session that he over-exerts himself, and he loves to play hard, I make sure he eats a snack afterwards and it's kept the low blood sugar incidents at bay along with more frequent, smaller meals.

Also, if you have a Chihuahua or other small breed, make sure you have honey, Karo syrup, or vanilla ice cream at the ready. My vet also recommended a supplement called Nutri-Cal, which is a high calorie supplement that provides extra energy. I hope you never have to experience this with your dog, but if you do, now you know how to handle it.

      Thank you for this. My Chihuahua has had severely low sugar for a few days now and the vet wants to put him to sleep because they can't find the cause. They say it will affect his brain if he keeps having regular bouts of low sugar so I'm looking for ways to keep it up.

      It just so happens I have a jar of honey in the cupboard from when my little brother came to stay (I despise honey lol) So I will try that.

      He isn't eating at all though so I am having to syringe feed him 5ml of prescription diet every hour and also syringe feed him a glucose solution.

      He is still crashing though, did your vet give you any other tips for getting his sugar up? My Mum has gone to buy ice cream so I will try that too. I just really don't want them to put him down, he is only 2 years old :(
