Switching your dog to a raw diet is an exciting step, but it's not unusual to notice a few changes while they adjust. One of the most common concerns new raw feeders have is diarrhoea during the transition.
In many cases, a temporary upset stomach is simply part of your dog's digestive system adapting to a new way of eating, and a mild upset stomach doesn't always mean something has gone wrong.
Keep the transition simple, introduce changes gradually, and avoid making lots of adjustments at once. If your dog is otherwise happy and their symptoms improve quickly, they're often just getting used to their new routine.
However, it's important to know what's normal, what you can do to help, and when it's time to seek veterinary advice.
Is diarrhoea normal when switching to raw?
Some dogs transition to raw without any digestive upset, while others may experience loose stools for a short period.
A change in diet can temporarily affect your dog's digestion, particularly if they've been eating the same food for a long time. This doesn't necessarily mean raw food isn't suitable for them—it may simply mean they need a little more time to adjust.
If your dog otherwise seems bright, is eating normally, and the diarrhoea settles within a day or two, it's often nothing to worry about.
Slow the transition down
If you've switched to raw quite quickly, it may help to slow things down.
Instead of changing everything overnight, try introducing raw more gradually over several days. This gives your dog's digestive system more time to adapt.
Every dog is different, so don't feel like you have to rush the process.
Stick to one protein
If you've introduced several different proteins at once, it can be difficult to know what's causing the upset.
Keeping things simple by feeding a single protein for a few days may help while your dog settles into their new diet.
Once everything is back to normal, you can gradually introduce more variety.

Check how much you're feeding
Overfeeding can sometimes lead to loose stools, especially during the early days of raw feeding.
Double-check that you're feeding the right amount for your dog's age, weight and activity level. If you're unsure, our Raw Feeding Calculator can help you work out a suitable daily portion.

Don't keep changing foods
When diarrhoea appears, it's tempting to keep switching foods in the hope of finding a quick fix.
In reality, constantly changing proteins or brands can make it harder for your dog's digestive system to settle.
Choose a quality raw food, keep things consistent, and give your dog time to adjust before making further changes.

Keep an eye on your dog
While mild diarrhoea during a dietary transition can happen, it's important to keep an eye on how your dog is feeling overall.
Contact your vet if your dog:
- Has severe or persistent diarrhoea.
- Seems lethargic or unwell.
- Refuses to eat.
- Is vomiting repeatedly.
- Has blood in their stools.
- Shows signs of dehydration.
These symptoms could indicate something more than a simple dietary adjustment.
Frequently asked questions
How long should diarrhoea last after switching to raw?
Every dog is different, but mild digestive changes often settle within a couple of days. If symptoms continue or worsen, speak to your vet.
Should I stop feeding raw if my dog has diarrhoea?
Not necessarily. If your dog is otherwise well, slowing the transition and keeping their diet consistent may be all that's needed. If you're concerned or your dog's symptoms are severe, seek veterinary advice.
Can I give treats during the transition?
It's often best to keep treats simple while your dog is adjusting. Introducing lots of new foods at once can make it harder to work out what's causing any digestive upset.
Will every dog get diarrhoea when switching to raw?
No. Many dogs transition without any digestive problems at all, while others may experience temporary changes as they adjust.
