“My dog has lymphoma and a high protein/low card diet is recommended. Hills N/D comes in canned but not in dry. So what’s the best dry dog food available with this nutritional mix? Thx
low carB (not low carD)”

Actually HD is not a bad product for a canned food. A dry comparison to about 40% protein.
This is the ingredient list;
Beef, liver, rice, menhaden oil, chicken, chicken digest, iron oxide, dried beet pulp, cellulose, potassium
citrate, calcium carbonate, L-arginine, dicalcium phosphate, taurine, vitamins and trace elements.

Foods of this nature are meant to maintain quality of life for as long as possible with terminally ill dogs.

For nonprescription dry foods Blue Wilderness and EVO come as close as possible, and this is what these diets were designed for —- NOT for the feeding a healthy dog.
