Diabetes is one of the more common hormone conditions we diagnose in dogs and cats, and it usually creeps in gradually. The good news is that with treatment most diabetic pets go on to live happy, active lives - the key is catching it and getting the management right.
Here's what to watch for, how we diagnose and treat it, and what day-to-day life with a diabetic pet actually looks like.
The four classic early signs
Diabetes develops when the body can't produce enough insulin, or can't use it properly, so sugar builds up in the blood instead of fuelling the body. The tell-tale signs come from the body trying to flush that excess sugar out:
- Drinking a lot more than usual
- Weeing more - bigger or more frequent puddles, or accidents indoors
- Losing weight despite a good (often increased) appetite
- Low energy, a dull coat, or just seeming 'off'
Dogs and cats aren't quite the same
In dogs, diabetes almost always needs lifelong insulin, and desexing females removes one hormonal trigger. In cats it behaves more like type 2 diabetes in people - closely linked to weight - and some cats, caught early and managed well, can even go into remission and come off insulin. That's a big reason not to wait if you spot the signs.
How we diagnose and treat it
Diagnosis is straightforward: an examination plus a blood and urine test to confirm high glucose. From there, treatment usually means daily insulin injections - which sound daunting but most owners master quickly - alongside a consistent diet and feeding routine.
Consistency is everything: insulin and meals at the same times each day keep blood sugar stable. We'll get you comfortable with injections, and use follow-up checks (and sometimes glucose monitoring) to fine-tune the dose. Our vet nurses run diabetic monitoring so you're well supported between vet visits.
When to call urgently
A diabetic pet that stops eating, starts vomiting, becomes very weak, or seems disoriented needs to be seen straight away - these can signal that blood sugar has swung dangerously. If you're ever unsure, phone us on 07 870 2696.
