Omega Alpha Probiotic 8 Plus - does not give amounts of ingredients

I went into my local health food store to get some Natural Factors probiotics for my cats and found Omega Alpha Probiotic 8 Plus in their pet section. The label has a picture of a cat and a small dog (yorkshire?) on the front and a list of ingredients on the back. It does not list the amounts of any the ingredients. Their website doesn't either. Did a bit of a web search and most websites are Canadian. Obviously walked straight across the store and bought the Natural Factors.

I can't remember the dosage suggested on the bottle - I think it was 4g daily for a dog. The company's website does not list the dosage. From a different website that offers this product for sale -- "Recommended dosage: 10-50lbs - 1/2 - 1 scoop (2-4g) daily.

Makes no sense not to list the amounts of ingredients. There's just not enough information to go on.

It seems to me I had this issue with some other PET probiotic.  That's why I stick to the human ones
