WE have a 10 year old Female Beagle who stopped eating about five days ago. She drinks a lot and is in good sprits.

5 days? That is too long for her not to be eating. Something is going on with her. We cannot exam her on line for us to be able to tell you what is wrong. Please call your vet and bring her in as soon as possible for an examination.

If you see the sticky on ''My dog won't eat'', https://www.askmehelpdesk.com/dogs/information-articles-our-dogs-expert-labman-53153.html#post254171
She needs to see the vet.
