Questions & Answers

30 Customer Questions

How many scoops are in each container?

Answer by Chewy • Apr 17, 2018
Each jar provides 45 scoops.

How long is the therapeutic dose?

Answer by Chewy • Jun 29, 2018
The therapeutic dose is the amount of the Dr. Mercola Complete Probiotics Dog & Cat Supplement required to produce the desired effect wanted from your veterinarian. If animal's condition worsens or does not improve, stop product administration and consult your veterinarian.

Is it ok to use with digestive enzymes?

Answer by Chewy • Feb 11, 2020
As digestive enzymes and probiotics have different functions within the body, they may be used together. Enzymes are proteins and probiotics are live organisms. That means enzymes can actually digest food and are effective at relieving common issues, including occasional gas, bloating, indigestion, heartburn and general discomfort. Probiotics, on the other hand, are useful in supporting overall health of the gastrointestinal tract as well as helping to support our immune system and the health of other body systems.

What is the country of origin for the ingredients in this product?

Answer by Chewy • Nov 09, 2018

My Dog and Cats are not in love with this rather expensive product. I thought the price point would indicate that they were more likely to enjoy it, it seems to have a higher review though when I have placed it on wet food it was left to be thrown out, the texture is, I believe to be too grainy or likely changing something that they have come to trust. Won’t purchase again. Though several others were suggested that I will check out.

I was so hoping this would be a benefit for my pets, but unfortunately, it did not agree with them. It created vomiting in a matter of 24 hours. I stopped it immediately and issues resolved. Unfortunately I have a whole jar on my shelf now.

So far its good easing the stomach

Its hard to get him to eat the food with it on it so I have to put a topping over it.

I was impressed at the number of strains and that there are 38 billion CFU

There’s no problem in putting it in my cats’ food and they seem to be doing well on it. I will continue to buy this for them.

I adopted two adult cats from a hoarder situation. It was evident they were not well taken care of with poor nutrition. When I took them home, they both had chronic diarrhea for months, I’ve tried different foods thinking maybe food allergies- could have been stress too. I’ve tried different probiotics. I was recommended this as it was multi-probiotics and within a week they both began to have regular solid bowel movements and I couldn’t be happier! They get half a scoop daily for maintenance. I add extra water to their food and it mixes well. They have no complaints about the taste- if there is any. My senior cat gets it too and no complaints from her either.

Darla has food sensitivities, her stomach is easily upset. Max has kidney disease as well as a fast thyroid. I put this on their dry food and mix it in. They seem to like it better with the powder than without it. Not sure if it's helping Max's kidneys, but it is helping everyone's digestion.

I use this for my cat. For a cat it is a half of a scoop which means my cat gets a different scooping each time. I wish they had a half scoop measurement on the scoop. In addition I wish it mixed better into the food. However the visible powder does not discourage my cat from finishing his plate.
