Hello Carrie
I had the same issue with my cockers this winter. vet said the UTIs could have been caused by the food which started a merry go round of other issues. I did use the D mannose which helped and switched them to Merrick and at that point, they began to eat their stools. I connected it to the new food which they loved!
Switched them to Natures Varity Duck Limited Ingredient and the other issues have (at this point) stopped. Had to watch some of the cranberry products, as some add Vitamin C which gave them loose stools.
Good Luck!
