Watery Stool Dog How Can I Make My Dog's Stool Firm And Hard?

How can i make my dog's stool firm and hard? - watery stool dog

I wormed my dog and his stools are soft and sometimes watery. very difficult to clean. I do not give food instead of table I give the dog food. say, the dog food company makes dog droppings and hard for a simple cleaning. Is that true?
I give high for Purina Pro represents 27% protein. is a good brand for my dog?

Thanks
