Is there a Science Diet Oral Care Small Bites, or is that only available in the prescription t/d?
Answer by ChewySep 24, 2017
At the time Hill's only makes the Oral Care Dry Dog Food and Prescription t/d Dental Care Dry Dog Food in standard size kibble.

Is this kibble as big as the prescription dental food from hills?
Answer by ChewyNov 12, 2017
The kibble is approximately 15 millimeters by 8 millimeters (about the size of a chickpea).

Can my dog have this as a regular meal only or Am I supposed to give it as a treat?
Answer by ChewyApr 27, 2018
This product can be used as a regular meal for your pup.

How does the science diet differ from the healthy advantage? I have a dog with anal gland issues that needs more fiber.

Tips and Tricks

The food has done an amazing job of clearing the plaque and tartar of my dog’s teeth. Unfortunately, the food has only been able to clear the tartar and plaque on one side of her back teeth. I don’t believe this is due to the food, but rather that she chews the food on one side of her back teeth. As much as the food has worked it did, however, take some experimentation to get her to eat the food, so here’s some tips and tricks to get your dog to eat the food. 1. Serve the food in the mornings as their first meal of the day (they will have no choice but to eat it.) 2. Serve the food with some of their favorite wet dog food. (They will be familiar with the wet dog food and it will entice them to eat the new food.) 3. If your dog is a picky eater or has sensitive teeth, you can add some water and microwave it for 10 to 15 seconds. (Depending) 4. If you’re desperate you can add their favorite wet dog food and microwave it. The smell of the wet dog food will get very strong that it will make them curious to the new food. 5. When microwaving and adding wet dog food be careful, don’t make the food too soft. The idea of the size and hardness of the food is that it takes your dog longer to chew which will have your dog use their back teeth. 6. Rotate the food with their regular food. So far these tricks have not affected the effectiveness of the food. I hope this helps. Good Luck!

Pieces are Huge!

My dog would not touch this because the pieces were huge. I tried breaking them apart but still would not even look at them. I wish he would, his teeth need this. Maybe it said on the bag the pieces were big and I just didn't notice.

Great so far!

Bought to use as treats for my German Shepherds and my pickiest one enjoys the food! It’s a hit in our household. Whether it still works or not as a treat is still to be determined.

nuggets are large

Even though there is a small dog pictured on the package, these nuggets are way too large for a small dog. I had to break them up with a rubber mallet.

Way too large for small dogs

I bought a bag for a 12 lb chihuahua mix. The main reason I bought this food was for the 12 lb dog whose teeth were cleaned in September and are so bad, he needs another cleaning in January. The vet suggested this food. I didn’t open it until today. In the meantime, I ordered a 2nd bag because I also wanted to add this to my 2 Golden Retrievers’ main diet. The kibble is NOT the size of a chickpea. It’s the size of a tater tot. My 12 lb dog cannot chew these huge chunks of kibble at all. He was the main reason I bought it. Wish Hills made an appropriate size for smaller dogs. This just won’t work my my little guy. One review here recommended cracking the kibble with a nutcracker. Seems like too much work when a market for a dental care kibble for small dogs definitely exists. Probably won’t buy again after my larger dogs finish these 2 bags.

Great Food

I have been feeding this food to my dogs for about a year now. It was recommended by my dog's nutritionist (one of my dogs has kidney health issues). At first I was worried they would not like the food but there have been no problems with it. It definitely does work for oral care as my dogs' breath does not stink at all and their teeth are clean. The kibble is pretty big but that is not an issue since I have medium sized dogs (50+lb), might want to reconsider if your dog is very small.

Extremely expensive, but a problem solver.

Kibble size is large, but that is so that your dog will CHEW it and get the tartar off of their teeth. The large size means they are using the back teeth, which is awesome. I have a chihuahua, so all the people with larger dogs saying it is too big to eat: nonsense. My dog's teeth look so much better, and we've only been using it a few weeks. Interestingly, she's been acting like a puppy, lots of playful energy, and up to mischief, and the dog food is all that's changed. It's great to see. My dog LOVES this dog food. My biggest problem is trying to AFFORD it. This dog food cost almost as much per pound as buying meat at the grocery store. I'd like to be able to afford to only feed my dog this product, but I've had a stroke while teaching, and my income is limited. Also, I wish they made a medium size bag, about 15 pounds. Excellent product, though high in price.

Our small dog gulped the nuggets

We started with a small bag of this dog food for our 20 lb poodle. She had to crunch each nugget individually and slowly and we thought it would really help clean her teeth. She soon discovered that she could gulp each bite rather than chew it. The nuggets are so large and hard that I don't recommend this for small dogs.

I make our dog’s food, but wanted to add a few “crunchies” for her teeth. She loves them so much we started using them for treats too. We found out our vet does that too!
