Reviews
it was a great product, my dogs really enjoyed it. i feel as though it is good value for the money you'd pay and it did help them to diet better. i felt it did fill them up throughout the day aswell
My dog really enjoyed his Hill’s dry dog food. I love how it’s got the velcro seal instead of the usual zip seal on his regular one. I found he wasn’t farting as much per usual. A larger size was great too. The price of it is just a bit too expensive for me to buy as his regular dry food though.
My dog seems to like the smaller bite-sized dry food. She enjoys the taste and her energy has improved eating all of her serving and looking for more [typical canine response to food]. Her coat also seems to be looking fuller and healthier. My dog gives this food a firm 10/10 and transitioned with no noticeable side affects.
"Winner Winner Biccies for dinner!"
Posted byTamBee1on31st Mar 2026Originally posted on hillspet.com.auBoth my Chihuahuas have been on this food for weeks and i have noticed a big improvement in their stools, they are much firmer and both dogs appear less bloated and overall seem content with this brand of dog biscuit, they can be fussy being Chihuahuas but they had nil issues at dinner time and adapted well to a change in diet. Very pleased to have tried this and will continue to use in the future
"My Dog loves Hill’s Science Diet"
Posted bySteph8on31st Mar 2026Originally posted on hillspet.com.auTrialling this dog food was a pleasure for me and my dog. She loved the taste and I noticed a positive change in her bowel movements and energy levels. We will be staying on Hill’s Science Diet for the foreseeable future.
