hi iam new here to this site but sooo glad i found it. i have a 16wk old american bulldog/lab mix(we think) who was on purina one puppy chow when i got her at 10wks of age. i slowly switched over to blue buffalo but i think the pieces were too bit cuz she had trouble eating it or didnt like it. then switched to innova adult food small bites(turkey chicken etc). she loves it but i was wondering if maybe its causing her stools to be a bit runny at times? im gonna keep track of her poops but was wondering what you guys would recommend if i need to switch(i know to mix old and new foods slowly for awhile).thank you for any tips!
