Customer Reviews

Hill's Prescription Diet b/d Brain Aging Care Chicken Flavor Dry Dog Food is rated 4.5 out of 5 by 20.
Rated 5 out of 5 by from Amazing help for CCD dog The symptoms of Canine Cognitive Disorder in my 11 yr old Lab mix were increasing and the effects of medications were decreasing when I read about Hill's b/d in a few articles on the Internet. My dog loves the taste and it's been two weeks and the change is great. He still needs his meds, but life with Buster is so much better. We don't have to leave the house to get away from him anymore and he's close to being my good friend again. After 7 months of getting worse every day, he's now improving. The food is expensive, but worth it. Chewy's fast delivery is wonderful. I wanted to start feeding as soon as I found out about the food and got Vet approval. They were extremely helpful and got the food to me the next day - with free shipping.

Rated 5 out of 5 by from Hill's Prescription B/D really works. I've never written a review but thought it important to write one on this product. If you're researching this product, I know you have serious concerns for your furry friend's behavior. This product really, really works! After only two days I noticed a marked improvement in his nightly behavior. Several months ago, my 9 year old Golden started having seizures (presumably a brain tumor). Several weeks later his evening behavior showed signs of dementia (Sundowners). He would pace, frantic panting, getting lost behind furniture and staggered walk. He was no longer sociable with me or my other dog. After 6 days now, these symptoms are almost gone. Because of the meds for his seizures, he's not as active as he once was - but I'll take it. For those who have issues with the 1st ingredient being whole grain corn -- I have always fed my dog the highest quality dog food (& most expensive) but he still ended up with a brain tumor and dementia! This product really has worked for my dog. I hope it will work for yours too.

Rated 5 out of 5 by from This product has great benefits for older dogs! My b/d prescription Science Diet arrived in record time so he has been on it for about two weeks. I see some improvements already, I wish I had put him on it sooner and would have if I had known about the benefits it has! Talk to your local vet get started early, he will love the taste and feel better!

Rated 5 out of 5 by from I was a skeptic, but I think this is working! Our 13-1/2 year old lab has been showing some signs of canine dementia - especially agitation, confusion and unseadiness. We've tried several different otc & prescription meds with little success, so when our vet recommended the Science Diet B/D we thought it couldn't hurt. We couldn't imagine a different food would help when we were already feeding a very high-quality diet, but we trust our vet. Lucy loves the food, and I guess it could be coincidence, but after she had been on the B/D for a little over a week, we started seeing significant improvement. She's steadier on her feet and seems more engaged than she had been - even resumed her lifelong habit of carrying her toys around. So whatever is behind this rally of hers....we'll be keeping her on the B/D because it's the only 'remedy' that seems to have helped our girl.

Rated 3 out of 5 by from food great bag too big My doggie likes the food. BUT I need smaller bags that fit in mouse-proof containers in my overflow food storage area known as the shelves by the basement staors (old house, Vermont, laid up stone foundation, mouse access). Instead I have to store it in my coat closet...not close to kitchen. ser

Rated 4 out of 5 by from My 14 yr old mini dachshund loves this dog food! Our mini dachshund loves this dog food. Her behavior has improved after being on this dog food for a week. Her random barking has decreased. We're hopeful that Hill's Prescription Diet b/d Brain Aging Care Dog Food will continue to slow down the awful (& sad) effects of her dementia.

Rated 5 out of 5 by from Well worth it for your old dogs mind... We took our old Jack Russel into the vet because we felt like there was something wrong that we couldn't see. Physically, there was nothing wrong with her. She is around 13 years old. We could see in her eyes that she wasn't recognizing us and she was becoming quite scared of her surroundings. The vet decided that she was getting doggy dementia and advised us to use b/d. Since putting her on the b/d food she has made a wonderful turnaround. We began to notice the difference in her within the first week of her eating it. She hasn't returned to her former self completely but, at least I know she isn't terrified of her own shadow anymore. Now there are many more "good brain days" than "bad" ones. We highly recommend this food for old dogs starting to lose their minds. It truly does help.
