What is similar to Kirkland lamb?

Nature's Recipe might be a good choice.

Diamond makes Kirkland.  They have their own natural Lamb formula that should be very similar. 

Our dogs were on Kirkland and I tried Nature's Recipe - got bad diarrhea from one of them. 

I can't vouch for the accuracy, but this is supposed to be an image of the Kirkland Signature Range Lamb & Rice Adult food:

This is supposed to be the breakdown:

Canidae lamb and rice (like Diamond lamb based food or Premium Edge Lamb based food) might be close to Kirkland's

Thank you all. That actually is very similar to the Premium Edge I was trying to switch to... so maybe the food isn't the problem

If metronidozal is an antibiotic you may want to do a quality probiotic follow-up to restore the balance of beneficial bacteria in the digestive tract.From my own experience many antibiotics can leave you with digestive upset.

Diamond Naturals is probably the closest you will get without causing any upset.
