Do you guys give probiotics long-term or just for medical issues? The vet gave Buster probiotics last week because the herbs made his stool very runny and stinky. They told me to use it twice a day for three days. Unfortunately, I have not been able to give it to him because it's a hassle. However, I need to administer it to him soon. Does it make the stool hard? He has megacolon and experiences difficulty passing poop; thus, he needs stool softners. I was wondering if the probiotics would counteract the softener.
