Questions & Answers

3 Customer Questions


Is this product meant to be paired with the prebiotics/probiotics manufactured also by the same company? Or does this include pre and probiotics as well?

Answer by ChewyDec 21, 2024
This product does not include probiotics. It can be given alone or with this brand's probiotics with prebiotics. Each Biotic (pre, pro, and post) has its own unique benefits to the health of your pet’s gut and works best when used in conjunction with each other.

How many calories are in each scoop?

Answer by ChewyAug 22, 2025

My Malamute and Husky were suffering with red itchy skin. They both eat a bit of kibble with home made food. Idk if they were suffering from their gut or seasonal allergies but my Husky had extremely bad itch around his eye that it started to bleed and his fur started to fall out and leave bald spot. I literally searched and searched and came across people on forums stating that adding probiotics helped their dogs. I gave it a go and this product has relieved their itch and red skin. My husky is getting his fur back and they seem relaxed and happier. Absolutely worth incorporating this in your dogs meals.

Cats Won't Touch It

I got this for my one cat who's been experiencing diarrhea. He wouldn't touch it mixed with wet food, water, etc. I have 10 cats total. I tried giving it to my other

I got this for my one cat who's been experiencing diarrhea. He wouldn't touch it mixed with wet food, water, etc. I have 10 cats total. I tried giving it to my other cats just to see and not a single one would eat their food with this on it, and half of my cats are not picky at all. I ended up giving this to my mom to use for her dogs just to get rid of it. Both of her dogs should get 4 scoops for their weight, but she just did 1 scoop for each of them. It made her one dog slobber really badly, so she quit giving it to that one. The other dog didn't have any issues, but again, she wasn't getting the full dose either. This product also has a very strong, unpleasant smell. I typically like Fera products, and I had high hopes for this one. Unfortunately, I do not recommend, especially for cats.

One scoop a day ...

Both cats, twin rescues, eat it right up! I give each 1/4 teaspoon a day, mixed with a little warm water, than add a tablespoon of wet food. They eat it right up,

Both cats, twin rescues, eat it right up! I give each 1/4 teaspoon a day, mixed with a little warm water, than add a tablespoon of wet food. They eat it right up, and their fur is soft, the heavier cat's dandruff has vanished, and they have regular, normal visits to the box!

Both of my boys have pretty sensitive stomachs and have been on Fera probiotics for a couple of years. We are so excited to add this Postbiotic to their routine. The herbs give this product a really nice earthy smell, and they loved the addition to their dinner. Looking forward to good digestion and healthy, solid poops :)

My dog constantly gets diarrhea. He has always had a sensitive stomach which is why it's so important for me to give him really quality postbiotics. These postbiotics help his gut and after giving it to him for a few weeks, I noticed his poop is MUCH healthier even if he gets into the trash can or eats grass.

Game changer for my dog!

My dog has always struggled with loose stool. It's been a constant battle which is no fun as a pet parent. I give my dog this Postbiotic along with Fera's Probiotic

My dog has always struggled with loose stool. It's been a constant battle which is no fun as a pet parent. I give my dog this Postbiotic along with Fera's Probiotic every day and the results have been incredible. He hasn't has loose stool in over a month now, when it was 3-4 times a week.

Satisfactory

Well the pets seemed not to be bothered with flavor. Not sure if that’s what I thought it would help with, with dogs
