Have you tried anything else to see if that helps? Could be an intolerance to something in that food. Blue is a somewhat controversial food, and people have issues that don’t seem like they should be happening. There is some murkiness with that company when it comes to laying it all out on the table. I don’t have any experience on it other than one puppy I got was on it so I bought a 5 lb to acclimate her to my house.
How long has the giant had the problems? If it’s just a day or two, you can try adding some pumpkin or probiotics to help her stomach. If it’s been longer, I would maybe bring her to the vet, or switch her diet to see if you can get it cleared up that way.
Which Blue Wilderness Blend is she (he?) on? Sometimes high protein can be a shock to dogs stomachs if they were on something else with much lower protein and jumped to something like wilderness
