Dog food for overweight dogs with sensitive stomachs

Sensitive stomach issues in dogs usually fall into a few categories — food intolerance, ingredient sensitivity, or a gut that just needs a simpler diet — and identifying which applies is the key to finding the right food. To point you in the right direction, it would help to know your dog's breed and age, what symptoms you're seeing (loose stools, vomiting, gas, or something else), and what foods you've already tried. What can you tell me?

That combination is actually quite common in older Basset Hounds — they're prone to both weight gain and digestive sluggishness, and the two problems tend to feed into each other. A calorie-restricted diet can sometimes strip out the things that supported gut health, so you end up managing one issue while quietly worsening the other. Can you tell me what he's currently eating, and roughly how much? And is the indigestion worse at any particular time — after meals, overnight, after exercise?

The post-meal timing and the improvement from the slow feeder both point toward fermentation in the gut — food sitting and fermenting rather than moving through cleanly. That's a digestion issue as much as a speed issue, and supermarket light foods often use high levels of plant-based fillers to bulk out the reduced calories, which can make fermentation worse. What you want is a light food that's genuinely easy to digest — low in fermentable fibre, moderate in high-quality protein, and formulated to support gut motility in older dogs. For a dog in his situation, I'd recommend Hill's Science Plan Adult Light with Chicken dry food. It's specifically formulated to support weight management without the cheap filler content that aggravates sensitive guts, and it includes prebiotic fibres chosen for digestive tolerance rather than just bulk. It's also developed with vet nutritionists and is well-established for older dogs managing both issues simultaneously. Keep the two-meal split you're already doing, and the slow feeder alongside it — that combination should make a noticeable difference.

Yes, it is. Hill's Science Plan Light runs at around 307 kcal per 100g, which is meaningfully lower than most standard adult dry foods sitting at 350–380 kcal. At 250g a day for a Basset Hound of his size, you'd want to confirm the exact portion with your vet since target weight matters more than a fixed gram amount — but you won't be undoing the progress. If anything, the improved digestive efficiency may help him absorb nutrients better and feel more satisfied on the same calories, which can actually support the weight management rather than work against it.

Gradually, especially given the existing gut sensitivity. A typical transition over 7–10 days works well — start with roughly 25% new food mixed into 75% current food, and increase the ratio every two to three days. With a dog who's already prone to indigestion, slower is better. If you notice any increase in soft stools or gurgling during the switch, just hold at that ratio for an extra few days before moving on. It's also worth mentioning the food change to your vet at his next check-in so they can factor it into how they're monitoring his weight.
