Wysong Corporation  is recalling some shipments of its dry dog food from its Maintenance and Senior product lines.

The company said certain batches are "above acceptable moisture levels and may contain mold."

Bags with the following lot numbers are in question and should not be fed:

• Wysong Maintenance - 090617, 090624, 090706 and 090720
• Wysong Senior - 090623

Moldy petfood ranges in severity,  according to reports , but vomiting and diarrhea is common, said veterinarian Lee Herold.

The above lots can be returned to retailers or replaced by the company.
