My picky dog only eats at night. Is this normal or concerning?

Pet's info: Dog | German Shepherd | Female | spayed | 8 years and 6 months old | 57 lbs

Hi! My 8.5 yr old female GSD has always been a picky eater and only eats when she is hungry. Not good motivated. I have noticed that she tends to wait to eat until late at night and doesn’t eat much during the day. She seems fine and does not appears to be sick at all. She does take 100mg cyclosporine and 200 ketconozole as a maintenance therapy for an anal fistula 2 years ago. Anything to worry about with the eating? Thanks!

Thank you for submitting your question regarding Abby. Is she maintaining a healthy body weight? If so and if she is acting like herself, then I would not be concerned about her food habits. It may just be her preference to eat at night. If she is consuming enough calories, then I do not have a concern. However, if she is continually dropping weight and shows signs of illness such as vomiting or diarrhea, then she needs to be seen by her veterinarian. Some dogs that go close to 24 hours between meals will vomit due to a build up of stomach acid. In these patients I encourage the owners to feed them more frequently. If this is not occurring with her, then you do not need to worry. I hope this information helps!
