I lost a corgi to cancer too, at 9 years. I’m thinking that there may be a genetic link, like with German shepherds and golden retrievers.
Anyway, I used to feed her about 1/2 cup of Nutrisca Salmon and Chickpea dry, but I would add a lump of chopped up chicken breast (cooked) or lean meat. Chopped up broiled chicken liver is good too. I fed her this twice a day.
You can add water to the cooked chicken and blend it with a smoothie wand, so that it is like lumpy thick gravy and put a tablespoon over her dry. You can soak the dry in the fridg overnight in water to soften.
She loved food and had a tendency to put weight on easily, but 3 to 5 mile walks daily seemed to keep her weight stable.
Brush her teeth every evening (YouTube has excellent how to videos).

PS: I get the chicken breast, lean meat at the reduced section of my local market, freeze then cook. I have been doing this for a long time and haven’t had any problems. Chicken livers are cheap, and you only add a little. Plus you can divide up and freeze.
If you weigh the dog once a week you will be able to see if she is gaining and decrease the amount. Get on the scale weigh yourself, then get back on the scale while you are holding her, then deduct your weight from the number you get 🙂 Do this before the first meal of the day.
