I add cooked lean meat or chicken to quality kibble (Nutrisca salmon and chickpea).
Is that a corgi in your avatar? I had one for 9+ years. Very healthy diet, exercise, never sick…..got cancer (hemangiosarcoma).
Another dog we had when I was a kid lived to be 18 years old, ate nothing but 1 can of Calo (cheap stuff) a day. Roamed outside free.

Both dogs had minimal vaccinations.

Some things are genetic and there is no explanation. We all do the best that we can.
