Your dog was just diagnosed diabetic. Now what?

So it’s not unusual to feel overwhelmed, confused, or even a little scared. In our experience, that’s completely normal. 

A diabetes diagnosis marks the beginning of a new chapter, one that comes with daily responsibilities, adjustments, and a learning curve. 

And more expenses for things like insulin and syringes; a blood glucose monitor and test strips; low-fat/no-carb treats; and other things you may need for your diabetic pet’s care. We've shared links to products and other resources that have worked well for us.

The good news is that many pet owners navigate this new phase successfully. There’s help out there; you don’t have to do this alone.

First, take a deep breath

Canine diabetes is a serious condition, but it’s manageable. With the right treatment plan, many dogs go on to live full, happy lives. They can be wonderfully resilient and continue to be an important part of our families.

That said, it’s important to be honest: managing diabetes is a daily commitment. It will require changes to your routine, close attention to your dog’s mood and behaviour, and regular vet check-ins. 

And you may encounter things you haven’t dealt with before. Parker has been diabetic for 2 ½ years and we still come across situations we have to research or seek advice as they are brand new to us.

Understanding the diagnosis

Diabetes in dogs typically means that your dog’s body is no longer producing enough insulin or isn’t using it properly. Without insulin, your dog can’t regulate their blood sugar levels, leading to a cascade of health problems if left untreated.

The most common signs of diabetes are:

• Increased thirst and urination
  
• Weight loss despite normal or increased appetite
  
• Lethargy
  
• Cloudy eyes (due to cataracts)
  

We knew something was wrong with Parker as he was drinking about a litre of water per day, which is a lot for a 10kg/24lb dog in the middle of a Canadian winter. He was lethargic – atypical for a terrier – and losing weight. 

Our vet diagnosed diabetes as they saw high blood glucose levels and the presence of glucose (and ketones) in his urine.

Managing a dog’s diabetes is all about consistency

One of the most challenging parts of having a diabetic dog is the regularity of their daily routine. Most diabetic dogs require:

• Twice-daily blood glucose testing
  
• Twice-daily insulin injections timed 11 - 13 hours apart
  
• A carefully timed feeding schedule
  
• A prescription or vet-recommended diet low in simple carbohydrates
  
• Regular exercise, but not overexertion
  
• Monitoring for signs of low or high blood sugar
  

Giving insulin might sound intimidating at first, but many owners are surprised by how quickly it becomes routine. Your veterinary team will show you exactly how to do it, and they’ll work with you to find the right dosage over time.

The first few months are the toughest

The initial adjustment period can be challenging. Your dog’s insulin dose will need fine-tuning. You may need to change their food. You’ll be learning to spot the signs of a blood sugar crash or spike. It’s a lot — but it does get easier.

During this time, patience is key. Be prepared for frequent vet visits, and know that frustration is a normal part of the process. But also pay attention to the small wins: a good blood glucose curve, a stable weight, a tail that wags like it used to.

Complications can happen

It’s important to know that diabetes can lead to other issues, including cataracts, urinary tract infections, or even diabetic ketoacidosis (a life-threatening emergency). Knowing what’s possible isn’t meant to scare you — it’s to help you stay proactive. The more closely you monitor your dog and stick to the treatment plan, the better their chances of avoiding complications.

You’re not alone

Thousands of pet owners are going through exactly what you are right now. Support groups, online forums, and your veterinary care team can all be valuable resources. Don’t hesitate to ask questions, request clarification, or seek emotional support. Most of all, remember that your dog is still your dog. The same eyes, the same loyalty, the same love. Diabetes changes things, yes — but it doesn’t change that.
