Our vet prescribed composure pro for our puppy to help with some nervousness. We have been giving it once a day for the past days or so. Can this cause soft/mushy stools? She's not going frequently and she is fine in every other way. Just seems to have soft poops

Hi there. This is not a common side effect of Composure Pro in my experience, but any oral medication could potentially cause some changes in stool consistency if Phoebe has a sensitive stomach. If it doesn't seem to be bothering her, I would suggest giving it a week or two to see if the problem resolves once she gets used to the Composure. If the soft stools continue, you can try stopping the supplement to see if they return to normal. In that case, it's possible that she might do better with a different calming supplement such as Solliquin or Zylkene.
