Pet's info: Dog | Yorkshire Terrier | Female | spayed | 11 years and 2 months old | 4 lbs

Hi, I have a dog breed Yorkshire, 11 years old and she is having acute diarrhoea since middle of October and had been checked for many examination like giárdia, other viroses and stool tests and the vets couldn’t find anything. We did a ultrasound and one clinic found abnormal size of her gal bladder and other clinic said that is nothing about it it. And they said it could be her colon, where I live we don’t have that much clinics and good equipments and professionals because it’s a Muslim place

I'm sorry to hear Mariquita isn't doing well. Some things you hadn't mentioned were food allergies which could cause diarrhea if there is an ingredient in her food that is making her ill. Your vet can try a food trial with you that involves narrowing down the ingredients fed to her and then reintroducing them over time to see if any triggers the problem. There are also prescription diets available for sensitive stomachs and food allergies that may help with the diarrhea as well. In some cases, probiotics can also help such as adding plain yogurt or a little pumpkin puree to help firm up the stool. If the above suggestions don't help, another workup from your vet to see if there was anything else missed may help.
