We love probiotics
I believe in probiotics because I’ve been using them myself for a long time, before doctors recommend them as they do today.
I’ve been giving Baci to my parrots for several years; I sprinkle probiotics on their moist food (vegetables, fruits, sprouts) once a week in prevention, to avoid unpleasant digestion surprises.
I bought Baci probiotics for my 16-year-old dog; she had been taking it for some time, but with age her metabolism changes and she needs the help that probiotics give her: her veterinarian advised me to give her once a day, which keeps her in a pretty exceptional shape for his age.
