“After a month, he’s recognizing us again and his pacing reduced. He’s much more like himself.”

"My 13 1/2 year old french bulldog wasn’t showing as bad symptoms as others have described, but he did display some behaviors that worried me. He used to stare off into space often, had a low appetite so he lost a few pounds, and generally seemed “lost” for a large part of the day. Sometimes I would let him out to do his business and he would forget what he was doing and just stand in the back for several minutes in one spot just completely still. I even had to call his name a few times for him to really “hear” me and respond to me (he isn’t deaf). He was almost a shell of the dog he used to be. I decided to do some research and give these a try. They absolutely reverted him back to his maybe 8 or 9 year old self. He’s always super alert, no longer has these “lost” episodes and his appetite has increased so much that he is eating more than he did even maybe a year or two ago! It has only been about 2month. My whole household is so happy to see this transformation. These supplements are expensive but so worth it to me. He will be on them for the rest of his life !"

"Bella stopped coming when I called her name. She'd just stare at the wall for hours. I was preparing myself to say goodbye. My vet said there's not much we can do and I felt so helpless. A friend told me about NAD+ and honestly, I didn't believe it would work. But I was desperate. After about 3 weeks, she started responding again. Not perfectly, but enough to give me hope. Now it's been 2 months and she sometimes greets me at the door, wags her tail, and even brought me her toy once. This isn't a miracle, but it's been really helping her."

"💯These really work for my 12 y/o dog. He has been taking them for about 8 weeks. Callie was hiding in tight spaces and then crying when he couldn't get out. Which really made me worry about leaving him alone. I came home from work and he was crying because he was stuck in-between the fridge and the wall as well as other similar incidents happening while I was at work. He was Pacing and standing in corners and staring at the wall and walking in circles. It all got worse in the late afternoon due to 🌄sundowners syndrome. 😥Like people dogs get it too. Now one of these at 3 pm and within two week he was so much better. He's not back to his old self because he still paces and stands in corners but he's able to relax and is looking easily redirected. He's so much better and he's not going in tight spaces anymore!

"Our border terrier is adopted and is over 13 years old. She is slowing down, was not finishing her meals and she was often found standing and staring into space. I prefer to try supplements first. More times than not, I can’t tell if they are making a difference. I did research and decided to give this one a try first. In this case, I do see a marked improvement. I ‘treated’ her for 90 days and forgot to order more. Within a few days, the staring into space returned. We also realized that the issue with eating was lack of focus. She used to get easily distracted and lose interest. It’s so much easier now that she eats all her food at mealtime, instead of bringing her back to her bowl multiple times. I just got her second dose and I plan on keeping it in stock.

"My 14 year old dog is in good health, but we had noticed her more and more seeming a little confused at night and occasionally staring at a wall. Potentially the start of Sundowners and/or dementia. I went ahead and got these to give a try. I held off a couple weeks before reviewing, but we’ve seen zero confusion over the past two weeks from her. She’s under 10lbs, so we’ve been giving her half a drop. We use it over her prescription food, and it also helps with keeping her interested in eating it. We started giving her Nordic Naturals fish oil also a week after starting these, but do think based on the immediate impact these are the likely main reason for improvement.

"I have a 8 year old dog. She had become withdrawn and would not let me touch her or pick her up. She always walked around kind of looking lost and sad. My vet recommended changing her food to one that supports senior dog cognitive functioning. She has a very sensitive stomach, and I knew that would cause her a lot of gastrointestinal upset. I bought these instead of the food to see if they would work. After about a week I knows she was more friendly and would come to sit on my lap. I asked my brother his opinion today. I had not told him before that I had been giving her anything or trying anything different. He instantly said she seems more friendly and will let him pick her up and hold her now. All I can say is this works for my dog, and I would suggest that you try it for your pup.

"My 12 yr. old dog was diagnosed with Canine Cognitive Disorder about 2 years ago. I started using a different supplement for brain health but it had to be squeezed into my dog's food and there are days that he doesn't eat very much so he wasn't getting the full benefit from it. When I saw that The Bark Labs NAD+ had a dropper I thought that might be of more help to him because I know it's getting into his system. I have definitely noticed an improvement in his symptoms, his anxiety has lessened quite a bit and he is calmer. Before he would pace the floor and try to get into things but that has improved quite a bit. I would recommend this product to anyone that has a senior dog who is suffering with Canine Cognitive Disorder. He also gets both wet and dry of a specialized dog food for brain functioning and in combination with this supplement he is a much happier dog! It has definitely helped me keep my sanity!"
Rachel F. - Beauceron Mix, 7 years old - Minneapolis, MN
"This saved my 15 year old golden retriever. After trying Prozac, conducting a DNA test, finding out he has drug sensitivity, and basically running or of options, this was a last ditch effort to get my dog back, and it's worked. He had gotten "sick" upon a move, when previous moves had had little to no effect on him. He was constantly anxious, confused, and terrified of the world around him, including me. This supplement brought him back. The first day he got the full dose he walked up to me with a wagging tail, I’m not sure if it was the supplement or luck, but it was the first time he's done that in a year. All I can say is thank you. After 3 months I can definitely see a big difference, he’s a lot more like himself. It might not work for every dog, but it saved mine and I'm forever thankful.

Why Give The Bark Labs NAD+ To Your Pup?
As dogs age, changes in the brain can affect memory, awareness, and behavior.
One key factor researchers have identified is a natural decline in NAD+, a molecule involved in cellular energy. Brain cells rely on this energy to communicate and function properly.
As NAD+ levels drop over time, it lead to confusion, disorientation, and behavioral changes. Which we call dementia.
Supporting NAD+ levels helps brain cells function more efficiently so your dog can stay more aware, responsive, and connected.
5,000+ dog parents have used this approach to support cognitive health
94% report their dog feeling more present and engaged after 90 days
Formulated to support cognitive function in aging dogs

Why Veterinarians Are Recommending NAD To Support Doggy Dementia
A recent study published in Scientific Reports found that dogs supplemented with NAD+ precursors showed measurable improvements in cognitive function within 8-12 weeks.
Follow-up research revealed that NAD+ supplementation reduced neuroinflammation by up to 40%, the same inflammation responsible for memory loss and disorientation in senior dogs.
Dr. Anthony Hall, DVM, Board-Certified Veterinary Neurologist, calls it "one of the most promising interventions we've seen for age-related cognitive dysfunction in dogs."

What’s Inside The Bark Labs NAD+
Every ingredient is carefully selected to support your dog’s brain as they age, safely and effectively.
NAD+
A key molecule involved in cellular energy. As dogs age, levels naturally decline, which affect how brain cells function and communicate.
What you may notice:
more awareness, more responsiveness, and moments where your dog feels more like themselves again.
NMN (Nicotinamide Mononucleotide)
A precursor your dog’s body uses to produce NAD+ naturally. Supporting this pathway helps maintain the energy brain cells need to function over time.
What you may notice:
improved focus, calmer behavior, and fewer “lost” or confused moments.
Resveratrol
A plant-based compound studied for its role in supporting healthy inflammation levels and protecting aging cells.
What you may notice:
less restlessness, reduced anxiety, and a calmer, more settled dog.
CoQ10
Supports mitochondrial function, which plays a role in how cells produce and use energy, especially in the brain.
What you may notice:
more consistent energy, better engagement, and improved day-to-day awareness.

One night we found my almost 16 and 1/2 year old stuck in the bathroom and repeatedly making circles. We noticed she also lost some of her sight. We took her to the vet and they said it could be three things…long story short they told us it was doggy dementia and some days will be harder. I think a stroke is what triggered all of this. Anyhow, I bought these with hopes it would help her brain heal and help focus. It’s been over three weeks now she’s sleeping during day and night and no longer walking in circles. I give one dropper a day. There’s a huge difference and I truly believe NAD+ helped correct whatever was missing in her brain. I’ll continue to purchase this product for her.

I'm writing this for my 4-pound toy Shih Tzu who has serious dementia and degenerative myopathy. He stopped eating. Just stares off into space. He's losing function of his back legs and it's heartbreaking to watch. He's only 9 and this is progressing at warp speed. While he's not in pain according to the vet, his eyes are empty and lifeless. I know we're losing him but I'm not willing to give up yet. If you're reading this, you're probably not either. I'm writing this review even though it's only been two days. I'm not sure if we see any improvement quite yet. I'll come back with an update in 6 weeks. God speed to all of you dealing with the impossibly heartbreaking, slow and painful loss of a beloved pet with dementia. I'd hug you all if I could.
Update: It's been six weeks and this has made a DRAMATIC difference. Kilo is eating again. The sparkle is back in his eyes. He's engaging and meets me at the door. He's even walking better and not falling as much. It's been nothing short of a miracle. We missed a couple days last week and there was a very noticeable change for the worse. Slept all day. Refused to eat. Staring into space. I'm just speechless and incredibly grateful for giving us more time together and for Kilo, a better quality of life.
Update Feb. 9th: We did end up losing Kilo at the end of January. Ultimately, he just stopped eating and drinking altogether. He died at home in my arms. He was not suffering but his little brain just ran out of steam. I wanted to thank the bark labs for creating this powerful product. It gave us 5 more quality months we never would have had without it. I wish I had known about it sooner. Neurological disease is insidious. NAD+ was our Hail Mary order that actually worked and went to war against the illness, alleviating symptoms for months. Most importantly, it gave Kilo and I a bit more of life's greatest gift. The gift of time. Thank you. 💕

These literally SAVED the life of our geriatric dachshund. He's around 17 years old and was showing severe signs of dementia. He would randomly start howling and biting at everyone and everything near him. Then start turning in circles. Getting dizzy. Stumbling around. He was up all hours of the night. Seemed to be very depressed. We didn't know what to do for him and thought the end might be near. I did some research and found Bark Lab NAD+ and decided to try it. After a few weeks of taking these drops, he was like a puppy again. The episodes completely stopped and he's just having a typical happy geriatric dog life. And even seems to have MORE energy than before. He loves going on walks. Barking at people mowing lawns. Loves his family. And even plays a bit with our younger dog. He pees wherever he wants and leaks urine. He can't hear. And his eyesight isn't great. Other than that, he's living his best life. He's been taking these for several months now and will be taking them the rest of his life.

We adopted Max from a shelter when he was 8 years old. Nobody wanted him because he was a senior dog. They said he'd probably only live another year or two. That was 5 years ago. Max has been the BEST dog we've ever had. Gentle. Loving. Patient with our kids. He's been through so much in his life. Abandoned. Neglected. Bounced between shelters. And somehow... he still had so much love to give. So when he started showing signs of dementia last year, I was heartbroken. After everything he'd been through... he deserved better than this. He deserved to live out his final years in peace. But instead, he was confused. Scared. Wandering around the house like he didn't know where he was. My husband said, 'Maybe it's time. He's had a good life with us. That's more than most rescue dogs get.' And he was right. But I wasn't ready. I found Bark Labs NAD+ and figured... if there's even a CHANCE this could help him... I have to try. The first month was hard. I didn't see much improvement. I started thinking maybe I was just prolonging the inevitable. But around week 6, something shifted. He started responding to his name again. Following me around the house. By week 10, he was playing with the kids again. Wagging his tail. Now at 6 months in, he's thriving. He's happy. He's more PRESENT. It’s not fully gone of course, but I'm so glad I didn't give up on him. He didn't give up on us when he was abandoned. I wasn't going to give up on him. ���

My wife passed away two years ago. Cancer. It was the hardest thing I've ever been through. Our dog Bailey was her dog. She picked her out. Trained her. Loved her more than anything. After my wife died, Bailey was all I had left of her. She was my connection to her. My reminder that she was real. That our life together was real. But about 8 months ago, Bailey started declining. She stopped responding to her name. Forgot basic commands. Would just stare at the wall for hours. It felt like I was losing my wife all over again. I couldn't handle it. My daughter kept telling me it was time to let her go. That I was holding on too tight. That I needed to accept it. But I COULDN'T. Because losing Bailey meant losing the last piece of my wife. I found Bark Labs NAD+ on a senior dog forum and ordered it that same day. I didn't tell my daughter. I didn't want her to think I was being irrational. The first month, I didn't see much change. I started losing hope. But I kept giving it to her every morning. Because what else was I going to do? Around week 6, she looked at me. With recognition in her eyes. By week 10, she was following me around the house again. Wagging her tail. Laying at my feet. Now at 5 months in, she's alert. She's happy. She's feeling better again. I got more time with her. And I know my wife would be so grateful for that. Thank you for giving me that gift.

I'm on a fixed income. This wasn't cheap for me. But watching my dog suffer was worse. I did the math and figured I could make it work. Best decision I've ever made. After 90 days, she's like a completely different dog. Alert. Happy. Present. I'd pay twice as much if I had to

I'm a retired pharmacist, so I don't fall for gimmicks. But NAD+ is legit science. My 12-year-old Shepherd went from wandering aimlessly to actually responding to commands again. Took about 5 weeks, but the change is undeniable.

I was so saddened to see and witness my little peekaboo losing interest, wandering at night, and distancing himself from the "pack." I have been trying to avoid prescription meds because the side effects can be an issue. I searched and scoured the internet for some guidance and possible alternative. After various searches and reading up on the various supplements on the market, I settled on ordering Bark Labs. Honestly, I thought it would be a placebo for me and have little effect on my furry housemate. Boy, I am gratefully wrong. He has regained much of his usual behavior and engagement. I cannot say whether it will do the same for your pooch, but it has made a world of difference for mine...thankfully.

This supplement has been very helpful. My almost 18-year old Lhasa that just started showing signs of cognitive decline in the last year. She now is alert again, no signs of anxiousness, no more endless circling, I have my dog back. This is my first pet and realizing age has set in the last 12 months has been sad and bittersweet. I only give her 1/2 the dropper at breakfast based on her weight. Ingredients are similar to supplements I take for longevity. Grateful I found this product.

I started giving this to my 13 year old Frenchie a couple of months ago. Truly, within just a couple of weeks her sundown moments pretty much disappeared. She jumps out of bed to go potty in the middle of the night less often (1-2 nights a week rather than every night, sometimes twice), and her appetite has improved!

My husband thought I was wasting money. 'It's just old age,' he kept saying. 'Dogs get old. That's what happens.' But I wasn't ready to accept that. Our dog had been part of our family for over a decade. He was there when we brought our kids home from the hospital. He was there through every birthday, every holiday, every major life event. And now he didn't even recognize us. So I ordered it anyway. Didn't tell my husband. Just started giving it to our boy every morning. After about 6 weeks, even my husband noticed the difference. Our dog was greeting him at the door again. Following him out to the garage. Laying at his feet while he watched TV. Now my husband tells everyone about it. Our neighbors. His coworkers. Random people at Home Depot. He won't admit I was right. But I know. And honestly? I don't need him to say it. I just needed our dog back. ❤️
