If your dog is diagnosed with diabetes mellitus, insulin therapy usually forms the foundation of treatment. However, diet also plays a large role; choosing the right food, keeping portions consistent and sticking to mealtimes can all help support the treatment plan recommended by your vet.
So, what can diabetic dogs eat and can they still enjoy treats? From choosing suitable diabetic dog food to building a reliable feeding schedule around insulin or medication, there are several things to consider. In this guide, we’ll cover the basics of feeding diabetic dogs, including which nutrients to look for, treat swaps to consider and how to create a routine that works for both you and your dog.
As every diabetic dog is different, always speak to your vet before making significant changes to their diet, feeding schedule or medication.
What Can Diabetic Dogs Eat?
For many diabetic dogs, a consistent diet with an appropriate balance of fibre, protein, carbohydrates and calories can form an important part of their management plan. Meal frequency and timing should be established with your vet, particularly when insulin is involved.
Proteins: Protein remains crucial for a diabetic dog's diet, as it helps to maintain lean muscle mass and also helps your dog to feel fuller. It’s best to focus on digestible animal proteins, especially if your dog also has a sensitive digestive system.
Fibre: An important nutritional consideration when it comes to managing canine diabetes; fibre helps slow the digestion of food and the absorption of glucose into the bloodstream. Veggies can be a good way to add fibre to your dog's diet, such as green beans, broccoli and Brussels sprouts.
Carbohydrates: Diabetic dogs don’t need to be on a zero-carb diet; however, the type and amount of carbohydrates they consume can be important. Complex and higher fibre carbohydrates can be preferred as they are slower digesting and prevent glucose from rapidly entering the bloodstream, while giving your dog the consistent slow release of energy it needs.
Calories and Weight Management: Weight management is one of the most critical factors when it comes to controlling canine diabetes. Obesity causes a resistance to insulin, making it much harder for them to use the insulin you inject. Working alongside your vet, you can determine the exact calorie needs for your specific dog. Dogs can lose weight rapidly before a diabetes diagnosis and will need a nutrient-dense diet to rebuild muscle and gain weight safely. Overweight dogs need a structured and gradual weight loss plan; your vet may likely recommend a specific weight management dog food.
Choosing the Right Diabetic Dog Food
There is no single dog food that’s perfectly suited for each individual diabetic dog. Your vet can help you choose a complete and balanced food that fits your dog’s individual needs, taking into account factors such as their weight, overall health, activity levels and diabetes treatment plan.
When comparing diabetic dog food options, look beyond individual ingredients and consider the nutritional profile of the food as a whole. A suitable diet should provide the nutrients your dog needs while helping you maintain consistent meal sizes and timings. Protein, fibres, carbohydrates and calories are all relevant when deciding on an appropriate diabetic dog food.
Consistency is also important; once you’ve found a food that works well for your dog, sticking with it and keeping feeding times the same can keep their daily intake and routine predictable. If, however, you did need to change their diet, it may be best to speak to your vet first, as they can help you manage the transition and may be able to recommend a veterinary diet for your dog.
It’s also worth getting familiar with the ingredients and nutritional information on your dog’s food label. Understanding what goes into their diet will help you be able to make more informed choices.
Building a Feeding Schedule for Your Diabetic Dog
A consistent feeding routine can make day-to-day diabetes management more straightforward. For dogs receiving insulin or other medication, meal timings may need to fit around their treatment plan, so always follow the schedule provided by your vet.
Keep Meals at Consistent Times
Try to feed your dog at roughly the same time each day, following the schedule recommended by your vet. Keeping mealtimes consistent can help make their food intake more predictable and can also make it easier to maintain a regular medication or insulin routine.
A regular schedule doesn’t mean you need to panic if a meal ends up coming a little earlier or later than usual. The important thing is to establish a routine that works for you and your dog.
It can help to build meals into your normal daily routine. For example, you might set reminders on your phone or use a written feeding chart to keep track of meals, treats and medications.
Measure Every Portion
Portion size matters just as much as meal timing. Measuring your dog’s food rather than estimating each serving can help you provide a consistent amount from one meal to the next.
A kitchen scale can be particularly useful for measuring dry and wet foods accurately. Follow the feeding amount recommended by your vet rather than simply relying on the general feeding guide on the packaging, as your dog’s individual needs may differ.
Don’t forget that treats, chews and other extras all contribute to your dog's overall intake too. Keeping these consistent and measured can help prevent their daily intake from gradually changing and their weight from fluctuating.
Feeding Around Insulin or Medication
For dogs receiving insulin, feeding and administration of their medication may form part of the same carefully planned routine. Your vet should give you specific instructions about when your dog should eat and when their insulin should be given.
Because treatment plans can vary, there isn’t a single feeding and insulin schedule that’s suitable for every diabetic dog. Don’t change the timing or amount of insulin yourself because you may have changed your dog’s food or feeding routine. If you are planning on changing your diabetic dog’s diet, feeding times or regular treats, speak to your vet first.
What if My Dog Won’t Eat?
A diabetic dog refusing a meal is something to take seriously, particularly if they are already receiving insulin. Giving your dog their dose of medication on an empty stomach can cause hypoglycemia. Rather than automatically giving their usual medication or insulin, skipping it or changing the dose yourself, consult with your vet first.
Similarly, if your dog is regularly refusing food, has a sudden change in appetite or seems unwell, you should contact your vet for advice. Keeping a simple record of meals, appetite, and any unusual changes can also provide your veterinary team with useful information when assessing your dog's routine.
Can Diabetic Dogs Have Treats?
Diabetic dogs may be able to have treats, but treats should form a small and consistent part of their overall diet. The type, quantity and frequency of those treats are worth considering alongside your dog’s main food, particularly if they are following a carefully controlled feeding plan.
There are some simple treat swaps that you can make, if approved by your vet. For example, you could use a small amount of your dog’s diabetic dog food as a reward; other options can include high-fibre vegetables such as steamed green bean pieces or cucumber slices, provided it fits their feeding plan.
If you do choose to use diabetic dog treats instead, choose options that are appropriate for your dog’s overall dietary plan and keep portions small. Veterinary diet snacks may also be suitable, particularly where a veterinary diet is already part of their management plan.
Remember to include treats when considering your dog’s daily intake, and if you’re unsure, consult with your vet to ensure regular treats don’t affect your dog’s feeding routine or medication schedule.
What to Avoid When Feeding a Diabetic Dog
When managing a diabetic dog, it’s not just their main food that matters. Unplanned snacks, table scraps and sugary foods can all add extra calories or nutrients to their diet or make their usual routine less consistent. As a general rule, avoid giving your dog:
Sugary Human Foods: Sweets, desserts, sugary drinks and other foods that contain lots of added sugars aren’t appropriate treats for dogs and should be avoided. Some human foods also contain ingredients that are toxic to dogs, so it’s best not to use human snacks as rewards.
Table Scraps and Leftovers: Leftovers can contain unpredictable amounts of fats and carbohydrates, adding extra calories to your dog’s daily intake. Doing so can also encourage begging and generally make it harder to keep track of everything your dog has eaten each day.
Unplanned Treats and Snacks: Regularly adding extra treats, chews or snacks can gradually increase your dog’s calorie intake. If you want to introduce treats into your diabetic dog’s feeding routine, check with your vet first and keep the amount consistent with your dog’s overall feeding plan.
Sudden Changes to Their Diet: Changing your dog’s main food or introducing lots of new foods at once can alter their nutritional intake and disrupt their established routine. Always make sure to discuss any significant dietary changes with your vet before making them.
It’s particularly important to remember that a food being safe for humans doesn’t necessarily make it suitable for dogs. If you’re unsure about whether a particular food or treat is appropriate for your diabetic dog, ask your vet first.
When to Speak to Your Vet About Your Dog’s Diet
Your vet should be a part of every significant change to a diabetic dog's diet and feeding routine. While general nutritional guidance can help you understand what your dog needs, their individual treatment plan should always take priority.
As such, speak to your vet before changing your dog’s main food, significantly altering portion sizes, changing meal timings or introducing new treats on a regular basis. This is particularly important if your dog is following a prescribed veterinary diet or receives insulin or another medication.
You should also speak to your vet any time that your dog’s appetite changes noticeably, they repeatedly refuse meals, or you notice an unexpected change in their weight or general wellbeing. These changes can have a range of causes, so they shouldn’t be managed by changing your dog’s food or medication without professional advice.
Keeping a simple record of what your dog eats, when they eat, and any treats they receive can be helpful when discussing their routine with your veterinary team. With the right diet, a consistent routine and appropriate guidance, feeding can become a manageable part of caring for a dog with diabetes.
Final Thoughts
Feeding a diabetic dog is about more than simply choosing the right food. A consistent diet, measured portions, regular mealtimes and carefully selected treats can all help create a predictable routine, while your vet’s advice should guide the decisions that are specific to your dog.
If your dog has been diagnosed with diabetes, speak to your veterinary team before making significant changes to their food and diet, feeding schedule or treats. They can also help you choose an appropriate diet and make sure it works alongside your dog’s individual treatment plan.
