Iams Proactive Health Minichunks Adult Dog Food vs Purina Pro Plan Adult Dry Dog Food

Both are solid adult dry foods with strong owner ratings, but they suit different dogs. The Iams Minichunks is the better pick for small breeds and picky eaters: the kibble is genuinely small, chicken is the first ingredient, and it comes in 7, 15 and 30 lb bags so you can size the bag to your dog. The Purina Pro Plan is the step up for owners who want a protein-forward formula with live probiotics and a shredded texture; it is a single 35 lb bag and costs more per pound in most stores. Reviewers on both sides praise palatability and firm stools; the common Iams complaint is the corn and grain content, and the common Pro Plan complaint is the jump in cost and the limited bag sizes.

• Choose the Iams Proactive Health Minichunks if you have a small or medium dog, want a small kibble, and want to buy in a bag size that matches your dog without committing to a 35 lb sack.
• Choose the Purina Pro Plan Adult if you want a higher-protein formula with live probiotics and a shredded kibble texture, and you are feeding a larger dog that will finish a big bag.
