Thank you for all of your replies, this has been very helpful!
Vomiting and diarrhoea in a young dog can have many causes including:
- An abrupt diet change
- An intestinal obstruction
Grey stool can indicate a liver /gall bladder issue but this would be rare in a dog that has been otherwise healthy.
As her gums are wet, it is unlikely she is dehydrated.
It is good she has not vomited today but not ideal she is not eating. She may well feel nauseous or have stomach cramps.
I would try and get some food into her before bed & hope she keeps it down. While she is generally raw fed, it may be worth offering some very bland and digestible cooked chicken and rice (a half portion) to her now.
I would then allow her to rest over night and hope she holds it down and begins to feel better.
However, if no better tomorrow morning I would want her checked over. The vet may wish to run some tests such as a blood test, faecal test or abdominal scan. She may well benefit from some medicine such as an anti nausea injection or antibiotics.
As there is a risk of food poisoning, be cautious when handling her poo and wash hands after any contact just in case.
Hopefully she is feeling better very shortly.
