Signs Your Dog Might Do Better on Raw Food

Most dog owners who start thinking about raw food do not begin by searching for raw food. They begin by noticing something is not quite right with their dog and wondering if food might have something to do with it.

The signs are often subtle and easy to write off as normal dog behaviour. Scratching that comes and goes. Stools that are never quite right. A coat that looks a bit flat. A dog that picks at their bowl instead of eating with enthusiasm.

None of these signs prove that diet is the cause, and none of them can be diagnosed from a blog post. What this article can do is give you a useful starting framework: a list of the signs that, in my experience as a canine nutritionist, often improve when a dog moves to a raw diet, and what to do if you recognise them in your own dog.

The signs below are observations from nutritional practice, not medical diagnoses. If your dog is showing symptoms that concern you, a vet check should come first. Diet can be considered alongside veterinary care, not as a replacement for it.

1. Persistent soft or inconsistent stools

A healthy dog on an appropriate diet should produce firm, small, relatively odourless stools. If your dog regularly produces stools that are soft, sloppy, variable in consistency, or very large and smelly, diet is one of the first things worth looking at.

Kibble-fed dogs often produce larger, softer stools because dry food contains a higher proportion of plant-based bulk that passes through partially undigested. Many dogs that switch to raw produce noticeably firmer, smaller, and less odorous stools within a few weeks.

Kizzy’s note: Stool quality is one of the clearest early signs that a switch is working. It is also one of the first things I ask owners to watch when they start the 14-day trial.

2. Itchy skin or recurring skin irritation

Itching is one of the most common reasons owners contact me about their dogs. The itch cycle, where a dog scratches, licks, or chews at the same areas repeatedly, can have several causes, and food is one of them.

Some dogs react to specific ingredients common in kibble: wheat, corn, soy, certain artificial additives, or specific protein sources like chicken meal (which is a very different product from fresh chicken). The reaction is not always immediate or dramatic. It can show up as low-level, chronic itching rather than an obvious allergic response.

Switching to a raw diet with a novel protein source, or to a single-protein raw food, removes many of the variables at once. Some dogs show improvement in skin condition within four to eight weeks. Some do not, and the cause turns out to be environmental rather than dietary.

If your dog has severe skin irritation, hair loss, open sores, or has been prescribed medication for a skin condition, keep working with your vet. A dietary change may complement veterinary treatment but should not replace it.

3. A dull, dry, or flaky coat

A dog’s coat is a visible indicator of their overall nutritional status. A coat that looks dull, feels dry or coarse, or sheds excessively beyond normal seasonal variation can sometimes reflect a diet that is not providing the right balance of fats and proteins.

Raw food tends to be higher in bioavailable animal fats than kibble, particularly when oily fish or appropriate supplements are included. Some owners report a noticeable improvement in coat quality after switching, though this is not universal and other factors, including parasite prevention, grooming habits, and underlying health, also play a role.

4. Low energy or lack of enthusiasm

Dogs vary enormously in their natural energy levels, so this one requires some personal knowledge of your dog. If your dog has become noticeably less energetic than they used to be, or seems flat and uninterested in things they previously enjoyed, and your vet has not found a medical explanation, diet is worth considering.

This is one of the harder signs to attribute to food specifically, and it should always be investigated by a vet first. But owners who switch to raw frequently mention improved energy and engagement as one of the first things they notice, particularly in the first two to four weeks.

5. Gassiness or a consistently bloated-looking belly

Some level of gas is normal in all dogs. Chronic gassiness, a persistently bloated appearance, or regular audible stomach sounds can indicate that the diet is not being digested efficiently.

Highly fermentable plant fibre, certain grains, and legumes that appear in many kibble formulas can contribute to excess gas production in some dogs. A move to a lower-carbohydrate, meat-based diet removes most of these sources.

If your dog’s belly looks acutely distended and hard, or if they seem in pain, this is a veterinary emergency and not a dietary question. Bloat in dogs requires immediate attention.

6. Not very interested in food

A dog that has to be coaxed into eating, or who consistently leaves food in their bowl, is not necessarily unwell. But low food motivation in a dog that used to eat enthusiastically can sometimes indicate that the current diet is not particularly appealing or satisfying.

Raw food tends to be considerably more palatable to dogs than dry kibble. Most dogs who have been reluctant eaters on kibble become noticeably more interested in mealtimes within the first week or two of switching.

Kizzy’s note: [Add a brief real-world example here. A sentence or two about a type of dog, not a named client, who showed improved food motivation after switching. Keep it factual.]

7. A dog that eats grass frequently

Dogs eat grass for several reasons, and occasional grass eating is normal. A dog that eats grass very frequently, particularly in the morning before they have had anything to eat, or who eats grass and then vomits yellow bile, is sometimes showing signs of an unsettled stomach or that they are not digesting their current food well.

This is not a definitive indicator and has multiple possible explanations. But it is one of the patterns that comes up regularly in my consultations with owners who are noticing something feels off with their dog’s digestion.

What to do if you recognise these signs

A 30-minute consultation with me is a good way to talk through what you are seeing and whether a change in diet makes sense for your dog. I will ask about your dog’s current food, the signs you have noticed, their weight, age, and any known sensitivities, and give you an honest assessment of whether raw is worth trying.

If you recognise several of these signs in your dog, the sensible first step is a vet check to rule out any underlying medical cause. Once serious health issues have been excluded, diet is a logical place to look.

If it seems like a good fit, a 14-day trial is a low-commitment way to see how your dog responds before making any long-term change.
