Hi everyone, I am thinking about switching Pixie's food to Merrick instead of wellness bc I always have to supliment her food with vegtables due to constipation. If she just eats the wellness I can gaurentee her poop is very hard, but if I give her green beans and pumkin it regulates her. so I was wondering if there is something in the puppy wellness that might be constipating her. Any suggestions would be appreciated.
