Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Roxy is adorable! Causes of diarrhea are: intestinal parasites, viral or bacteria infections, dietary indiscretion (ate something gross), food allergy/intolerance, new treat/table food. I would deworm her and be sure she is up to date on vaccines. I would change her to a bland diet of boiled chicken or hamburger with rice. Feed 1 cup per 20lbs per day until the stool is normal. Then try changing to a different brand of puppy food. Also consider a probiotic like Purina Fortiflora. If there is no improvement then I recommend a Vet exam. I hope this helps and I wish you and Roxy the best!
