Reviews
My little cavoodle has a very sensitive tummy, any change in her food will usually be seen at the other end. When transitioning to this food to trial, she didn't have any problems and immediately loved the flavour, never leaving any food in the bowl.
My dog really enjoyed this food, she’s not usually a big eater of dry food but she has been loving this and eating it daily which is very rare! Her coat has improved and her skin hasn’t been as itchy
"Healthy dog food that she loved."
Posted byDeirds10on1st Apr 2026Originally posted on hillspet.com.auOur dog absolutely loved this dry food. She didn't have any tummy reactions to it. It smelt quite nice too. Will be looking at purchasing once this is finished. Thanks
My Cavoodle Luna loved this Hill's Science Diet Sensitive Skin and Stomach Food. From the first introduction she was right into it, clearing every morsel. It did not take too long to substitute her usual dry food to 100% Hills. What I loved about this product, besides the fact my dog gobbles it up, is the fact that it did not have any adverse effects of Luna's tummy, weight, behaviour, or appearance. It appeared to be easy for Luna to digest, her bowel motions were firm, she didn't look for more food so it definitely filled her up and there was absolutely no waste at all. During the whole month Luna has been eating this food there has not been one single negative reaction, thank you Hills.
As soon as I opened the package, my dog loved the product; for the first couple of days she was excited and considered the food as a treat eating everything. Things changed after a couple of days and the size of the kibble is slightly larger than the ones she’s used to and after 4 weeks I still haven’t managed to wean her off the old food. She’s eating grass from the garden and the stool is not quite well formed yet. Overall the experience needs longer, and it can be expected, but I never experienced it with another feed.
