I’m considering purchasing this brand of supplement. Want to clarify something. Does one treat (for 11 lb dog) have 320 mg of ginkgo biloba?
Answer by ChewyMay 06, 2019
The ingredients list is per 4 chews so there is 320 milligrams of ginkgo biloba in 4 chews.

Are these soft treats? My senior dog only has 10 teeth...
Answer by ChewyMay 06, 2021
This treat is a soft chew.

Can you feed your dog 2-3 treats for joint health and 2 or 3 for memory health in one day . 25 lb mini golden doodle- 14 yrs . We just discovered regular joint health chicken treats - she loves them . Should we just use Sr treats
Answer by ChewyAug 21, 2021
We encourage speaking with your Veterinarian before combining supplements, for the safest opinion.

How many of these chews come in a bag?
Answer by ChewyJul 28, 2021
Each bag will include 90 treats.

Brain Food

I actually think this might work if you start your pup on it sooner than later. Unfortunately, I fall into the latter category. I didn't find out about this supplement until Roofus was already showing strong signs of doggy dementia. But after only a month on Brain's Best Friend, I can see some cognitive improvement. I'm going to start my young seniors on it now before they start showing signs of decline.

My 15 yo started acting confused and was pacing nonstop. Desperate, I looked for something to help. Started these and after about a week, she improved dramatically. She acted happy to see me again after just staring at me blankly before. She's more like her old self, but not 100%. She is still pacing at times, but not for hours at a time. Hopefully she will continue to improve.

Very tasty

I only gave these four stars because it is too soon to determine if they make a difference in my 10 year old boy's memory health. He loves them, so I know they are very tasty. There aren't a lot of choices out there when you're searching for something to give your dog if you suspect memory issues. I'll follow up in time whether this treat seems to be making a difference.

Brain Treats

We had noticed some cognitive problems in our nearly 15 year old pup. While not officially diagnosed, she was showing signs of “doggy dementia.” Her anxiety seemed to be worse, too, in her twilight years. I found these and thought I’d give them a try. She finds these to be tasty and seems to be generally less anxious and more like herself. I will continue buying them, if nothing else, just because she enjoys them.

My dog didn’t like taste.

My dog, a 15 year old Poodle, will not even touch them, didn’t like taste.

They LOVE their treats

I received this product “complimentary" for testing purposes. I can honestly say my dogs both of adult age, loved these treats. I mean, what dogs don’t love treats; but I actually tested them. I would lay one of their regular milkbone biscuit treats in front of them as well as laying the recommended serving size of the ark naturals treats right next to their biscuits. Every time they choose Ark Naturals. I can’t give information about how well they work or don’t, as my dogs can’t tell me. I did however notice that they were more content and maintained a calmer demeanor when we had company. Scooby usually is hyper when company comes over. After regularly giving him these as treats daily, the incidents were less. I would recommend and would consider purchasing in the future!

Picky pups

I love the ingredients and what is supposed to happen to help my pups with this product. I have two senior pups who were just not interested trying a new treat. I was given them free for my review.

Old girl loves them!

I recieved these for free and cannot stop talking about them. My senior dog loves them and I started to see results almost immediately. She's a lab/shepherd mix and is almost 13 years old. Sometimes she looks a bit confused especially when someone comes in the house (people who live here), even me. After we started these she seems to realize and recognize who are without barking or getting riled up.

Dogs can't get enough!

*I received these treats free for an honest review.* I have 2 senior dogs so it was a great product to try. They love them! Of course I won't complain with it being beneficial for their health. Also made in the USA! I like that they're smaller so I can use them to work on a couple commands.

Great product

My old girl has been struggling lately. A lot of fear and anxiety. From the 2nd dose she seemed more confident. I’m glad I tried Brains Best Friends. Everyday she seems happier. A lot like her old self. She is now a 13year and hopefully I will be able to keep her happy for a while longer. Thank you
