Diarrhoea after a change of food
- If your pet eats something that they aren’t used to, it may give them diarrhoea unless it’s introduced slowly.
- This type of diarrhoea usually passes with very little treatment, but it’s important to make sure your pet improves quickly and stays hydrated.
- It’s important to be sure that there are no other possible causes for your pet’s diarrhoea – contact your vet for advice.
- Contact your vet immediately if you think your pet has eaten something that could harm them.
When to contact your vet
Diarrhoea due to a change in food usually settles within a few days. However, if your pet’s diarrhoea is severe or left for too long they may become dehydrated and poorly. Contact your vet without delay if your pet has any of the following symptoms:
- Diarrhoea for more than a few days
- Eaten something that may harm them
- Intermittent diarrhoea for 2 weeks or more
- They are very young or very old and have diarrhoea
- Diarrhoea and other health issues
- Diarrhoea whilst taking medication (especially anti-inflammatories)
- Diarrhoea in rabbits should always be checked by a vet.
Home care for diarrhoea
If your pet has diarrhoea (without blood or mucus) but is otherwise happy, well and behaving normally you could try to settle them at home. If they don’t improve quickly or you are concerned about them at any point book an appointment with your vet. Diarrhoea in rabbits should always be checked by a vet.
