After supermarket chain Mercadona pulled Compy wet dog food off shelves in select stores in Spain due to reports of pets suffering from kidney failure, dog owners are submitting claim forms to a new website set up by those living in Spain. But, the dog food’s manufacturer is urging concerned consumers to contact them directly instead.

“We believe it is easier and faster for those affected to contact us directly,” said manufacturer Tunaliment’s pet division spokesman, Miguel Fernandez.

The manufacturer’s veterinarian reports found that excessive vitamin D levels in the wet dog food, which is sold in aluminium-lined cartons, may have caused kidney failure in pets. According to the manufacturer, this relates only to the new packaging and not to the previous, tinned wet dog food.

Consumers can contact the manufacturer of the Compy wet dog food directly at informacion@tunaliment.com or +1.619.113.976.
