In short- YES!
Diarrhoea is a sign of an unhappy gastrointestinal tract and is characterised by watery or loose bowel movements. It may have mucous or blood in it.
It’s a non-specific sign and can have many causes.
- change of food or being fed an inappropriate food
- food intolerance or allergy and parasites.
It can be mild and improve without much intervention but it can also be severe and if left even a short time can lead to dehydration which a puppy is particularly susceptible.
Advice from a veterinarian should always be sought and in severe cases emergency treatment and supportive therapy may be required.
