Hi Leslie
Would you consider making your Jack a homemade diet? If he has no food allergies or intolerances a homemade diet using chicken, beef, turkey, fish, pork and other meats would be beneficial for your pup. You would use lean meats, 10% fat or less. Lightly cook the meats. Add about 20% non-starchy pureed veggies and fruits. Occasionally add some organs and sardines.
Supplement with Omega 3 oils, digestive enzymes, probiotics and a vitamin mineral mix like Steve Brown’s See Spot Live Longer Dinner Mixes and you have the basics of an economical, highly nutritious, species appropriate low carb diet that would help your precious pup do the best he can!! Turmeric is an excellent supplement for dogs with cancer. Slight adjustments to the diet with fiber would depend on the needs of your dog.
This is not that hard to learn and there are plenty of people here to help you along the way! I wish you and your pup the BEST!!!
