Fellow dog owners - what food do you feed?

[Monty the BP]

Kirkland brand from Costco alternating between chicken and lamb, fish oil and vitamin E, coconut oil & raw meaty bones every now and then.
both are shepherd mixes.

You know I bred and showed pugs for 7 yrs and so many breeders use the Natures Domain which is only sold at Costco, they swear by it. I did a lot of research on that brand and have to say it seems to be a good brand.
