Probably. If there is a possibility of immediate surgery following the results of the X-ray or MRI then no. Call the office and leave a message. They will get back to you immediately.
For the image itself, it depends on what body part will be checked. But it is always good to keep them on an empty stomach in case we need to sedate to get the image, unless the doctor instructed you otherwise.
No need to not eat for xray or ultra sound. People dont have to not eat so i imagine animals dont either.
