Hill's Pet Nutrition is expanding on a recall of certain canned dog food products that occurred earlier this year.  The recall is due to concerns of potentially elevated vitamin D levels.

Affected dogs may show symptoms such as vomiting, loss of appetite, increased thirst, increased urination, excessive drooling and weight loss.  People that have given their dogs any of the products listed below should not continue to do so.

No dry foods, cat foods or treats produced by Hill's Pet Nutrition are being recalled.
