My Dog Won't Eat his New Kibble: What Should I Do?

Some dogs will happily eat anything that's put in front of them. Others seem to notice even the smallest change in their bowl.

If your dog has started refusing a new kibble, don't panic. It's a common situation, and in most cases there's a simple explanation. Whether it's the size of the kibble, the flavour, or the way the new food was introduced, a few small adjustments can often help your dog enjoy mealtimes again.

Why won't my dog eat the new kibble?

There are several reasons why your dog may be turning their nose up at a new food.

The kibble may not be the right size

Size matters, especially for puppies and small breeds.

If the kibble is too large or difficult to chew, your dog may become frustrated during mealtime and eat more slowly—or stop eating altogether. Choosing a recipe with kibble that's appropriate for your dog's age and size can make a big difference.

They don't like the flavour or texture

Just like people, dogs have personal preferences.

Some love rich, meaty aromas, while others prefer milder flavours. Texture also plays a role. Some dogs enjoy crunchy kibble that encourages chewing, while others are more attracted to softer foods.

If your dog refuses one recipe, it doesn't necessarily mean they're a picky eater—they may simply prefer a different flavour or texture.

They may not be feeling well

A sudden loss of appetite isn't always related to food.

Digestive upset, dental pain, or other health problems can make eating uncomfortable. If your dog refuses food completely, appears lethargic, or shows any other unusual symptoms, contact your veterinarian for advice.

How can you help your dog accept new kibble?

Introduce the new food gradually

Changing your dog's diet overnight is rarely a good idea.

Instead, mix a small amount of the new kibble with their current food and increase the proportion gradually over 7–10 days. This gives both your dog's digestive system and their taste buds time to adjust.

Stick to your usual routine

Dogs thrive on consistency.

Serve meals at the same time each day and in the same place. Changing both the food and the feeding routine at the same time can make the transition more difficult.

Give your dog a little time

Some dogs simply need a few days to get used to a new smell or flavour.

If your dog is still eating a little, try to be patient. Avoid replacing meals with treats or table scraps, as this can encourage fussier eating habits.

Make the meal more tempting

A few simple additions can make kibble much more appealing.

Try:

adding a splash of warm water to release more aroma;
mixing in a little unsalted chicken broth;
adding a drizzle of salmon oil.

These small changes often encourage reluctant dogs to give their new food a try.

Try a different recipe

If you've introduced the food gradually, ruled out any health problems, and your dog still refuses to eat it, they may simply not enjoy that particular recipe.

Dogs have favourite flavours too. Switching from chicken to beef, lamb, duck, or salmon—or choosing a recipe with different ingredients—may be all it takes to make mealtimes enjoyable again.

Choosing high-quality food made with carefully selected ingredients also helps ensure every bowl is both nutritious and delicious.

Patience is key

Most dogs eventually accept a new food when the transition is slow and positive.

The goal isn't simply to get your dog to eat—it's to help them enjoy every meal while providing the balanced nutrition they need to stay healthy and active.

If your dog refuses all food for more than 24 hours, or if the loss of appetite is accompanied by vomiting, diarrhoea, lethargy, or any other unusual symptoms, seek veterinary advice promptly.

Frequently Asked Questions

Why won't my dog eat the new kibble?

Your dog may dislike the flavour or texture, the kibble may be the wrong size, the diet change may have happened too quickly, or there could be an underlying health issue. If the problem persists, speak with your veterinarian.

Why doesn't my dog like the new food?

Dogs develop individual food preferences. A different aroma, ingredient, or texture may simply be less appealing than their previous food.

How can I make kibble more appealing?

Adding a little warm water, unsalted chicken broth, or a small amount of salmon oil can enhance the aroma and flavour, making the meal more tempting.

What's the best way to switch to new kibble?

Introduce the new food gradually over 7–10 days by mixing it with your dog's current kibble and increasing the proportion little by little. Keeping your usual feeding routine also helps make the transition smoother.

My dog suddenly stopped eating kibble. Should I be worried?

Check whether anything has recently changed, such as the food, feeding routine, or environment. If your dog refuses food completely for more than 24 hours, or shows signs of illness, contact your veterinarian as soon as possible.

What should I do if my dog swallows kibble without chewing?

Kibble in a size suited to your dog’s breed will encourage chewing. A slow-feeder bowl or a snuffle mat, where the kibble is hidden and found one piece at a time, can work very well. Mixing a little wet food with the kibble changes the texture and naturally slows eating, while making the meal even more appealing.

Is supermarket kibble harmful to dogs?

Kibble sold in supermarkets is not harmful, provided you choose a quality product. Where it is purchased matters less than the composition of the food itself. Well-selected supermarket kibble may suit your dog perfectly and, in some cases, even better than veterinary kibble.

Dog kibble with or without grains?

Dog kibble containing grains is not harmful when properly formulated, and grain allergies or intolerances are very rare in dogs. Grains are often assumed to mean gluten, but this is not always the case. Rice and maize, both widely used, do not contain gluten. Gluten is found in wheat, barley and oats, but this does not automatically cause problems for dogs, which are rarely intolerant.
