Signs of a poor diet

Understanding the signs of a poor diet in dogs is essential

Understanding the signs of a poor diet in dogs is essential to ensure that your dog is being fed the right amount of good, healthy food each day. There are a number of obvious signs that they’re not getting everything they need, but some symptoms are easily missed - take a look at our guide for an idea of what to look out for.


Poor digestion can usually be spotted when you take your dog outside - if they’re suffering with diarrhoea or constipation, it’s usually a sure sign that they’re not feeling very well! This kind of problem usually only occurs if they’ve eaten something unhealthy, so keep an eye on what you’re feeding them and take note if something upsets their stomach.

If it’s a more regular occurrence, there could be a problem with their diet or another underlying problem, so you should always speak to a vet to find out what’s wrong. Unusual stools can also give you an indication - take a look at our Guide to Poo for more information!


Weight gain is often seen as a marker of a poor diet in dog - usually correctly - but weight loss can also be a sign that they’re not getting the nutrients they need to keep them at a healthy weight. It’s healthy to weigh your dog once a week, unless your vet advises differently, and this should give you a good opportunity to see any changes as they happen. Remember that weight gain and weight loss can also be symptoms of other problems, so don’t make any major changes to their diet until you’ve spoken to a vet or one of our in-store nutritionists!


Irritated skin can often be a sign of food allergy, or that your dog isn’t getting the right amount of fats and oils from their diet - they need a certain amount for their skin and coat to stay shiny and healthy. If they seem to be scratching a lot of their skin seems unusually dry, this is a sign that you might need to talk to a vet or nutritionist. Sometimes the food might be right but they may have developed an environmental allergy, so it’s always worth checking all possible options when you’re looking for a solution!
