Diabetic Dog Companion is a free tool for owners of dogs with diabetes. It helps with part-meal dose adjustments, glucose curve logging, diet planning, and puts the most important facts close at hand.
It never sets or changes your dog's insulin dose — that is always your vet's decision. All guidance is sourced from the 2018 AAHA Diabetes Management Guidelines and manufacturer package inserts.

This page does arithmetic on the dose your vet prescribed — it never sets or changes that dose itself.
If your dog ate only part of the meal, adjust the dose. Drag the slider, or weigh what's left for an exact figure.
For a recurring part-meal or a second missed meal in a row, phone your vet rather than adjusting the dose yourself.
The general rule used by most diabetic dog communities is: the reading should be above 11 mmol/L (200 mg/dL) before you inject. This gives the glucose room to drop to a safe level without going into hypo territory.
| Reading after feeding | Guide |
|---|---|
| 11 mmol/L+ (200+ mg/dL) | Give the usual dose |
| 9–10 mmol/L (160–180 mg/dL) | Give ¾ of the dose |
| 8 mmol/L (144 mg/dL) | Give ½ of the dose |
| 5.5–7 mmol/L (99–126 mg/dL) | Give ¼ of the dose |
| Below 5.5 mmol/L (below 99 mg/dL) | Do not inject — treat for hypo |
Never give insulin to a dog showing hypo signs, or one that hasn't eaten. If you suspect a hypo, treat it straight away and phone your vet. This table is community guidance — your vet's instructions for your dog always take priority.
Never inject less than 11 hours after the previous injection. Two doses working at the same time significantly increases the risk of a dangerous low. If your injection is late, skip that dose rather than shortening the gap.

The green band is the target range (5.6–13.9 mmol/L · 100–250 mg/dL). Gold dashed lines are your meal/injection times; the green shaded bands are walks. The lowest point (the nadir) is marked in red — it is the number your vet uses to judge the dose.

• Weakness or wobbling
• Trembling or shivering
• Glassy or unfocused eyes
• Confusion or disorientation
• Unsteady walking, stumbling
• Seizure or collapse
If you see any of these — act immediately. Do not wait to test.
Never give insulin during or after a hypoglycaemic episode until glucose is fully stabilised and your vet has advised you on when to resume the normal schedule.
Common causes include: too much insulin relative to food eaten, a smaller meal than usual, unusual exercise shortly after injection, a fur shot where the dose was repeated, or the Ketoconazole drug interaction (which reduces the body's ability to counteract insulin). Tell your vet which you suspect.

There's a lot on this page, but to begin you only need two things: how much to feed, and — if you need a new food — one that isn't too high in fat or starch. Here's the short path. Protein, fibre and the meal builder can wait until you've found your feet.
Enter your dog's ideal weight and activity level to see daily calories — then the food list below shows grams per meal.
Based on the Waltham Energy Calculator. Use ideal weight — not current weight if your dog has lost condition.
Mix up to 3 foods and check the total calories and combined fat. Search by name to pick from the list — or enter values manually for any food not listed (e.g. fresh mackerel).

Enter figures from the food label. Fat and moisture give you the true fat; add protein, fibre and food type to also get an estimated carbohydrate figure.
Diabetic dogs do best on low fat, high protein food with fibre to steady blood glucose. The right balance depends on your dog's weight. Tap to see the targets, then use the sort buttons in the food finder below to check your food against them.
Guidance figures based on the 2018 AAHA Diabetes Management Guidelines and current veterinary nutrition evidence. Always confirm your dog's diet with your vet.
About this fat guidance: there is no single official guideline stating an exact fat ceiling for diabetic dogs in general. 14% dry matter fat is a widely used practical threshold, not a proven safety limit, and some dogs do fine well above it. Below 10 to 12% is better supported specifically for dogs with a history of pancreatitis or very high triglycerides. If your dog is underweight, restoring weight and muscle matters more than restricting fat. Ask your vet what is right for your dog.
If your usual food runs out or your dog goes off it, this works out how many grams of a different food gives the same calories per meal.
