The manufacturer of a high end dog food brand under investigation for its connection with more than 70 dogs falling sick, offered to reimburse vet bills and replace dogs that have been euthanised.

Advance Dermocare dry dog food was voluntarily recalled after a number of dogs which had eaten the food have contracted megaesophagus.

The rare condition causes the oesophagus to become enlarged and lose the ability to move food down to the stomach meaning that the surviving dogs need to consume their food sitting upright.
