Pet's info: Dog | Chihuahua | Female | unspayed | 7 years and 6 months old | 6 lbs

I have a 7 yr old female Chihuahua with sudden onset of lethargy accompanied by diarrhea last night. Her stool is bright yellow this morning but she seems to be a bit brighter. She wasn't even moving last night and refused water but this morning she is wagging her tail and seems a bit more energetic.

It sounds like she has taken a sudden onset bout of gastroenteritis. If she seems brighter you can try starving her for 12 hours then feed her plain chicken and rice. If she continues to refuse to drink or is getting worse you should go to the vet as it could be something more serious.
