Hi,Lisa! I am a new frenchie mom. She is 4 months old. We have had her for 3 weeks. Ever since we brought her home, she has had loose, runny stools. She has been treated for giardia and is now clear. The breeder had her on Royal Canine. I switched her to Wellness. I've seen so many suggestions on which food is the best for her, that I feel so confused! Any suggestions?
