Henry had a tough first year digesting food and with loose stools. We very slowly started him on the Embark and Perfect Form and things got much better fairly quickly. He was finally having some normalcy and we were just so relieved to not see him straining and looking uncomfortable when he went outside. He no longer had gas and burping. After lots of trips to the vet and being told to put him on a prescribed food (which did "solidify things", but looked awful, smelled awful, and ingredient wise was terrible), we decided to give this brand a try. We are so happy that we did. Things are great and Henry no longer is that dog with the ultra sensitive stomach. We only use the Perfect Form when we need to now. He has more recently switched to Force and is doing equally as well.
