Is she having diarrhea?
What is in the vomits?
What is her diet?
Is she up to date with her vaccines?
Don't go, we just got started
So she is still eating fine but she vomits after eating?
How long after eating?
Is it undigested food?
Okay, I recommend to not have any activity for now
Only walks on leash to go to the bathroom
Then back inside
I would try as bland diet
Consisting of boiled chicken and rice
How much does she weigh?
She is intact? When was her last heat cycle?
She can have 1 x 10 mg tablet of Pepcid (famotidine) every 12 hours
Any vaginal discharge?
Do you have a thermometer then you can use on her rectally?
Pepcid is an antacid medication, what over the counter antacids do you have there?
It is not uncommon for dogs to not have a heat cycle until 24 months of age, it could not be related, why I ask about the thermometer is to make sure that she does not have a temperature
Let me check what you have there in the uk
You should have Pepcid ac there
Does this not sound familiar?
Okay I would try the Pepcid then every 12 hours for the next 3 days
10 mg every 12 hours
What time is it right now?
