About this app

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.

Insulin & doses
Set your dog's dose in My Dog
How the Part-meal helper works

This page does arithmetic on the dose your vet prescribed — it never sets or changes that dose itself.

  1. Your dog's dose is entered in My Dog, not here — along with the syringe type and when insulin's given. Set it there once and it appears at the top of this page from then on.
  2. Usual dose vs give this time. The Part-meal helper shows both side by side — the standing dose your vet set, and what to give for this particular meal if your dog didn't finish it.
  3. Drag the slider, or weigh it properly. Roughly how much was eaten works fine, but entering the grams given and grams left turns it into an exact figure instead of a guess.
  4. Not sure how much to feed in the first place? The Diet section works out a recommended weight from your dog's ideal weight and activity level — for one food, or a combination of several in the Meal builder. That's the figure to use as food given here.
  5. Once-daily basal insulin (Toujeo, Tresiba) is different. If that's what's set in My Dog, the whole Part-meal helper disappears — feeding and injecting aren't tied together the way they are with Caninsulin or ProZinc, so there's nothing here to calculate.
Your prescribed dose
Always feed first, then inject — give the full dose unless your dog ate less than a full meal (use the part-meal helper below).

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.

Checking the reading before you inject

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.

If the reading is below 11 mmol/L (200 mg/dL) before the meal, give the meal first, then retest after 30 minutes. If still below, retest again after a further 30 minutes, then use the table below as a guide — always confirming with your vet what is right for your dog.
Reading after feedingGuide
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.

The 11-hour rule

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.

Monitoring
Glucose readings & curve

Glucose curve

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.

Emergency — Hypo guide
Low blood glucose treatment
Signs of hypoglycaemia (low glucose)

• 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.

Treatment — do this now
1
Give sugar immediatelyRub a small amount of glucose gel, honey, corn syrup or golden syrup on the gums and inner cheeks. Do not put anything in the mouth if your dog is unconscious.
2
Wait 5–10 minutesKeep your dog calm, warm and still. Do not leave them alone.
3
Test if you canIf your dog responds and you can test safely, check the glucose. A reading above 5 mmol/L (90 mg/dL) is a good sign.
4
Offer a small mealOnce alert, offer a small amount of food to help stabilise glucose.
5
Phone your vetEven if your dog appears to have recovered, your vet needs to know. A hypo episode may mean the dose needs reviewing.
⚠ If your dog does not respond to glucose gel within 10 minutes, or loses consciousness, go to an emergency vet immediately.
Do not inject

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.

What causes a hypo?

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.

New here? Start with these steps

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.

  1. Enter your dog's weight. In Daily calorie calculator just below, put in your dog's ideal weight, activity level and meals per day. It works out the calories per day, and how many that is per meal.
  2. Already have a food? Type its name in the Food finder and it shows the grams to give per meal — that alone is enough to get started. You can also search it in the Meal builder if you'd like to combine two or three foods.
  3. Choosing a food, or checking yours? In the Food finder, use the fat filter — ≤14% (a common working threshold) or ≤10% (a more conservative target if your dog's had pancreatitis) — and the carbohydrate filter — Lower, Moderate or Higher estimated carb. Both are useful starting points, not hard rules; some dogs do fine outside them. You can also tap Sort by: Lowest fat. Each food shows the grams per meal for your dog.
  4. Food not on the list? Use the DMB checker — enter the fat, moisture, protein and fibre from the label and it works out the true fat figure plus an estimated carbohydrate figure, so you can compare properly. Or add it properly in the Meal builder's "not in list" box with the figures from the label — it's remembered as one of your foods, and from then on it shows up as your current food in the Food swap calculator and the Food finder too, so you can compare it against anything on the list. This is worth doing for a newly diagnosed dog especially, since the old food often isn't on the list at all.
  5. Feeding more than one food? Use the Meal builder. Add your main food first — its amount fills the meal automatically — then add the other foods by the amount you actually give, and the main food adjusts to keep the meal on target.
  6. Food run out, or your dog's gone off it? Use the Food swap calculator below — pick your current food and the new one, and it works out the grams that give the same calories, so the switch keeps the meal on target from day one.
  7. Later, when you're ready. Protein and fibre matter too — but don't worry about them at the start. They're shown on every food for when you want them.
  8. Two golden rules. Change foods slowly, over 7–10 days (see "Changing your dog's food" in Learn), and whatever the app suggests, your vet always comes first.
Daily calorie calculator

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.

Meal builder

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).

Fat filter:
Backup & restore

DMB fat & carb checker

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.

Dry foods typically show 8% moisture. Wet foods are usually 75–82%. If moisture isn't on the label, use 8% for dry and 78% for wet.
Diet targets for your dog

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.

Food finder (184 foods)
Food swap calculator

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.

Only foods with calorie data appear in the lists. The true fat figures help you judge whether the new food suits your dog. Talk to your vet if you're not sure.
