The capsules contain 5 billion microorganisms and 8 different strains. In addition, each capsule also contains 10 billion CFU/gram of good bacteria. The capsules do not contain dairy. Vetri-Science Mega Probiotics are good probiotic for everyday use and rate our FOUR STAR ranking. 

Our dog probiotic research looked at the list of specific probiotics (or the names of the individual strains of bacteria) in each product for sale. According to vets, (and this is true for their human friends as well), each strain of bacteria does something helpful and different for the body. In many cases, too many different kinds of bacteria can not be helpful as they tend to cancel each other out. Probiotics lose their effectiveness (die) over time. Use the probiotic product well before its expiration date.
