Our 8 month has had issues with soft (often very soft) stools since we got her. We've treated for giardia 4-5 times, tested for giardia and worms many times, and last month had full blood panel done to check for anything else going on. All checks out. The only thing we've found (finally) that immediately hardened up her poop overnight was Science Diet W/D (we previously tried I/D but did not help). We're happy we finally found something that works, but a 70 lb dog goes through a bag way too quickly and it is obviously quite expensive. Our vet recommended slowly trying to taper off the W/D with mixing it with her food, but as soon as we get below a 50/50 blend the poop goes soft again. We tried using some fiber supplements in her food since the W/D is a high fiber food, but it hasn't helped. Figured I'd see if anyone had any recommendations on something comparable to W/D with a more affordable price.
