Hypoglycaemia in Dogs: Causes, Signs and What to Do

Hypoglycaemia in dogs, or low blood sugar in dogs, is a medical emergency that can quickly become life threatening. Causes include too much insulin in diabetic dogs, missed meals, severe illness, liver disease, heavy exercise, certain toxins and hormonal problems. Puppies and small toy breeds are most at risk. Early signs are weakness, tiredness, shaking, hunger and restlessness; severe signs include confusion, unsteady walking, seizures, collapse and unconsciousness. If the dog is conscious, give food and a quick sugar source such as honey or glucose syrup, gently rubbing a little on the gums if needed. If the dog is unconscious do not force food or drink, rub a small amount of sugar on the gums and contact your vet immediately. Veterinary treatment may include intravenous glucose, blood sugar monitoring, insulin dose changes and treatment of any underlying illness. To help prevent episodes, keep regular meal and insulin routines, avoid long fasts, monitor at-risk dogs and keep puppies warm and well fed. Quick recognition and prompt veterinary care improve the chance of a good recovery.

    Diabetes in Dogs: Signs, Causes and How to Manage It

    Diabetes in dogs is when the body cannot use or make enough insulin, so blood sugar stays too high. Early signs of diabetes in dogs include increased thirst, more urination, greater appetite, weight loss and low energy. Vets diagnose diabetes with blood and urine tests. Most dogs need lifelong insulin therapy plus a steady diet, regular exercise and routine feeding times to keep blood glucose stable. Owners should monitor for hypoglycaemia (weakness, trembling, collapse) and for serious complications such as cataracts, infections or diabetic ketoacidosis. Keeping dogs at a healthy weight, providing regular exercise and attending routine vet check ups can lower some risk factors. Contact your vet if you notice increased thirst or urination, unexplained weight loss, sudden lethargy, vomiting or other worrying changes so treatment can start early and improve your dog’s outlook.

    Diabetic Ketoacidosis in Dogs: Causes, Symptoms and Emergency Treatment

    Diabetic ketoacidosis (DKA) in dogs is a life‑threatening emergency that happens when the body cannot use glucose and produces too many ketones. It usually affects dogs with uncontrolled or newly diagnosed diabetes and can be triggered by missed insulin, infection, stress or poor appetite. Common signs of DKA include increased thirst and urination, weight loss, tiredness, poor appetite, vomiting, rapid or laboured breathing and a fruity smell on the breath. Vets diagnose DKA with blood sugar and ketone tests plus checks for dehydration, electrolytes and organ function. DKA treatment is urgent hospital care with intravenous fluids, insulin, electrolyte correction, feeding support and treatment of any infection. To help prevent DKA give insulin exactly as prescribed, keep regular meal times, monitor blood sugar if advised and call your vet promptly if your dog becomes unwell. Many dogs recover well with fast treatment, but delayed care worsens the outlook, so contact your vet or an emergency clinic straight away if you suspect DKA.

    How Hot Is Too Hot? The Danger of Hot Cars for Dogs

    Cars can become deadly for dogs in minutes, even on mild days. There is no safe outside temperature to leave a dog unattended in a car. Vehicles act like greenhouses and heat up fast, and cracked windows do not stop this. Around 20°C outside can already be risky and 22 to 24°C can quickly become life threatening inside a car. Flat faced breeds such as Bulldogs, Pugs, French Bulldogs and Boxers, plus puppies, older dogs, overweight or thick coated dogs and those with heart or breathing problems are at higher risk. Early signs of overheating are heavy panting, drooling, restlessness and bright red gums. Later signs include vomiting, collapse, seizures and loss of consciousness. If a dog is overheating move it to a cool place, give small sips of cool water, wet their body with cool water, increase airflow and call a vet; do not use ice cold water. Never leave a dog alone in a warm car. If the weather feels warm to you it is probably too warm for a dog. Leaving a dog in a hot car can cause severe suffering and may lead to fines or prosecution.

    What Are the Signs Your Dog Is Sick?

    Signs your dog is unwell include changes in appetite or thirst, vomiting or diarrhoea, low energy, coughing or laboured breathing, altered behaviour, skin or coat problems, trouble moving, eye or ear discharge, bad breath and sudden weight change. Seek veterinary advice if symptoms persist or worsen, and get emergency help for collapse, difficulty breathing, severe vomiting, a bloated abdomen, seizures or suspected poisoning. Regular vet checks, vaccinations, parasite control, good dental care, balanced food and exercise help prevent many health problems. Trust your instincts if your dog seems 'not themselves' and act quickly to get help.
