  • So far so good...

    By on

    Only reason I didn’t rate higher is I haven’t even had my pups on this kibble for a full month so I am unable to report long term differences at the moment. THAT BEING SAID, the small size of the kibble is perfect for my girls (two, senior, female Chihuahuas who’ve both lost most of, if not all of their teeth.) and they seem to like it! (They free feed kibble) So far so good!

  • Big bite senior dog food great!

    By on

    I have always fed my dogs Iams and they love it! From puppy all the way to Senior! Currently I have 3 Senior dogs, (ages 10,11,12) three different sizes, and One pup -only five years old. The large breed is excellent for dogs that need a large kibble but the food is easy to chew if they are missing teeth or teeth are worn down. Even my smaller dogs try to gobble it up! Chewy.com has been the greatest thing for me since sliced bread! Fast shipping! Love autoship and great prices! I am surprised at how much time is saved not having to make a trip to my "Pet" store! Thanks Chewy!!

    I had a 14 year old Golden retriever mix, she loved this dog food. I had to cancel my monthly orders since I had to put her down this past Thursday May 11th. Service was great, came on time FedEx put box right where I wanted it.
