Diabetic dog feeding schedules: how to sync meals, insulin, and glucose curves

Stable diabetes in dogs is built on three synchronised clocks — the insulin peak, the meal, and the post-prandial glucose curve. Get those aligned and a newly diagnosed dog often halves its insulin dose within a month. Here is the feeding protocol I run in referral, with brand-specific carb numbers, a home curve you can actually do, and the five timing mistakes that send dogs to the ER.

Heart disease in dogs: a low-sodium diet plan that fits real life

A cardiac diet is not 'just less salt'. Sodium restriction, protein quality, omega-3 dosing, and taurine/carnitine status all stack together to slow the disease and let medications work better. Here is the plan I build for dogs in my referral caseload, with brand-specific numbers and the four mistakes owners make in the first 30 days.

Weight management: how to use the Body Condition Score (BCS)

The scale lies. A 30 kg Labrador and a 30 kg Greyhound have radically different body fat percentages, and the number on the bathroom scale cannot tell you which one needs to lose weight. The Body Condition Score is the clinical standard for a reason — it works, it is free, and any owner can learn to do it. Here is the 9-point method I teach in consults, the four assessment errors that lead owners astray, and the exact caloric math that turns a 20% weight loss plan into a daily portion.

Food allergies: the 8-week elimination protocol

Adverse food reactions account for roughly a third of allergic skin disease in dogs — and the only way to diagnose them is the elimination diet trial. Here is the exact 8-week protocol I run with my clients, the brand-by-brand hydrolyzed and novel-protein options, and the four most common ways owners accidentally invalidate the trial and have to start over.
