Hello, congrats on your new addition  , as you probably know there are numerous different brands and varietys of dog/puppy foods on the market, i personally think it is a matter of trying out what is popular with you own dog, and what he/she prefers.

As with my chihuahua, she has always been fussy and particular with foods, so it was a case of trial and error.
Keep us updated on your progress 

Regards

Sarah
