  • Easy and affordable

    By on

    I have 3 large, large breed dogs in my home and we were feeding them a cheaper brand food because we go through so much and the price was right. Ordering thru Chewy.com got us the same amount of a better brand of food for a slightly higher price than what we paid for the cheap food. Our dogs have transitioned well and I am very pleased with the process!

  • We love it

    By on

    Our parents have been giving us IAMS since we were adopted and we love this lamb and rice iams the best. We do get tired of the same ole thing so our parents treat us to IAMS proactive health large breed as well to switch it up. Our bellies handle the change well and it helps to not get over weight with the lamb and rice food.

  • Quality, healthy food by 2 bassets love.

    By on

    Ok, lets face it... Basset hounds would eat anything, but they do love the Iams ProActive Adult Lamb food. I feel good buying it for them. I could not find the larger sized bag in my grocery, so I was very happy to find it on Chewy.Com. And for a much, much better price.

  • Not the same product

    By on

    This is NOT Lamb and Brown Rice; they have dramatically changed their formula. Lamb is now the fifth item on the ingredients list. And the bag says “WITH grass fed Lamb.”....brown rice has disappeared. Our dog definitely has noticed the difference. It feels deceitful to change their formula so much but still make the bag appear virtually identical.

  • Good food at reasonable price

    By on

    My schnauzer had a GI bleed twice w/ beef based dry food so vet recommended lamb or chicken based. Did this food switch about 6 yrs ago & no more GI bleeds or any stomach concerns from any of my 4 dogs & they all like it!

    I have been feeding my dog 2 1/2 year, Iams since I got him. So I thought to mix the Mini Chunks with the Lamb. He really likes it. Price was really great and AUTO saves me from worrying about ever running out of food
