Quick answer: Low blood sugar (hypoglycemia) in dogs is an emergency. If your dog is weak, wobbly, disoriented, or having a seizure, rub a tablespoon of honey, maple syrup, or corn syrup directly onto their gums, then call your veterinarian or an emergency clinic right away. Once your dog can swallow safely, offer a small meal of protein and complex carbohydrates to keep their blood sugar steady while you get them checked.
I'm Preston Smith, co-founder of Bully Sticks Central. Hypoglycemia is one of those things that looks scary and moves fast, so the most useful thing I can do is walk you through exactly what to do in the moment, and how to keep it from happening again.
What are the signs of low blood sugar in a dog?
Hypoglycemia comes on quickly and gets worse if it isn't treated. Watch for lethargy or sudden weakness, a wobbly or drunken-looking walk, trembling or shivering, confusion or a glazed stare, pale gums, and in severe cases collapse or seizures. Toy and small-breed puppies, very active working dogs, diabetic dogs on insulin, and dogs who have gone too long without eating are the most at risk, according to the American Kennel Club.
How do you treat low blood sugar in dogs at home?
If your dog is conscious and can swallow, feed a small amount of food right away. If they're too weak to eat, or you see trembling or seizure activity, rub a sugar source onto the gums instead:
- Rub sugar on the gums. About one tablespoon of honey, corn syrup (such as Karo), or maple syrup rubbed onto the gums and inner cheek gets absorbed even if your dog can't eat. VCA Animal Hospitals recommends this as an emergency measure.
- Follow with a real meal. Once your dog is alert and swallowing normally, give a small portion of their regular food or a protein-rich snack so their blood sugar doesn't crash again in 20–30 minutes.
- Call your vet no matter what. Low blood sugar is usually a symptom of something else — an underlying illness, an insulin dose that needs adjusting, or an infection. Even after your dog perks up, have them examined so you treat the cause, not just the episode.
- Never force liquid into an unconscious dog. If your dog is seizing or passed out, don't pour syrup down the throat — apply it to the gums only and get to an emergency vet immediately.
How can I prevent hypoglycemia from happening again?
Once the emergency passes, prevention comes down to keeping blood sugar steady throughout the day:
- Feed smaller, more frequent meals. Especially for small-breed puppies, several small meals a day prevent the long gaps that trigger a crash.
- Build meals around protein and complex carbohydrates. These release energy slowly and hold blood sugar more evenly than sugary treats.
- Keep a fast sugar source on hand. A small bottle of honey or corn syrup in your bag and car means you're never caught without one.
- Work with your vet on the underlying cause. If your dog is diabetic, has recurring episodes, or is a very young toy breed, your vet can help you fine-tune diet and, if needed, medication.
Do treats and chews affect blood sugar?
They can, which is why I'm careful about what goes into ours. Sugary, heavily processed treats can spike and then drop a dog's blood sugar. That's a big part of why every product we make at Bully Sticks Central is 100% natural, single-ingredient, 100% real meat — no added sugars, fillers, or rawhide. Our single-ingredient chews are fully digestible and made from meat that's ethically sourced from grass-fed American and Argentinean farms, so you always know exactly what your dog is eating.
If you have a puppy — the group most prone to hypoglycemia — our guide to bully sticks for puppies covers safe chewing options for little dogs. And when you want a longer-lasting chew that won't spike blood sugar, a natural bully stick is a simple, protein-rich choice. Everything we sell is 100% high-quality guaranteed.
When should I go straight to the emergency vet?
Go immediately if your dog is having a seizure, is unconscious, doesn't bounce back within a few minutes of getting sugar on the gums, or has repeated episodes. Hypoglycemia can be life-threatening, and a professional needs to find and treat what's causing it. When in doubt, call — most vets and emergency clinics will talk you through the first few minutes on the phone.
