Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I am sorry to hear that Petitte has cancer and that it has spread. I typically recommend using the prescription diet Hills and feeding N/D (neoplasia diet) with any diagnosed cancers. This diet is a proprietary blend of antioxidants and nutritional ingredients to help dogs with cancer especially going through chemotherapy. Your vet will need to prescribe this food as it is a prescription diet. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
