My dog has digestive upset and vomiting. Is Blue Buffalo the cause?

Poor Theo! Given that he was throwing up the Blue Buffalo (BB) food, but now isn't vomiting on the Simply Nurish, I would suspect that the BB isn't agreeing with his stomach. As for his poop, changes in diet can lead to looser stools. Even though you did half and half to help him switch, typically it's better to do 1/4 new food and 3/4 old food to start. To help Theo with his diarrhea, I can give you a home remedy to try. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. I would also recommend getting Theo's vaccines done ASAP if he's seven months of age. I see that you are in Utah, and a rabies vaccines for all dogs is required by law, so it is important that he get that vaccines plus the DHPPi combination shot (distemper, parvovirus, hepatitis, parainfluenza) once he is feeling better. I would wait until the diarrhea has cleared up before getting him those vaccines. I hope this helps :-)

I'm sorry Hulk has been having problems with soft stool! It could be that his diet was causing the diarrhea, but it could also be that he had a GI illness or ate something rotten. It's good that the bland diet has helped clear it up, and I would find another food to feed him besides Blue Buffalo. I am not a fan at all of it, there are many cases of dogs having GI issues on it. It also have very poor quality control over how it is made, and they have had a number of recalls. Brands of food I recommend include Royal Canin, Hill's Science Diet, Purina ProPlan, and Iams. You can get his used to one of these new brands by slowly adding it to the bland diet, and over time, increasing the amount of the new food and decreasing the bland diet until he is eating the bland diet only. Good luck, I hope this helps!

Poor Addison! This could be caused by several things from large water intake, parasites, or even her dog food. Blue buffalo can actually be too rich for some dogs. I have also seen other complications from eating blue buffalo like bladder crystals and bladder stones. You some consider switching her to something With less protein like science diet, Royal canin, or Iams. If you want a food with a more “natural” approach, natural balance is also a good choice. When you switch her, I would slowly mix in the new food and gradually transition her over a 10 to 14 day period. Also, I would have your vet take a look at her. Your vet will be able to do a fecal to check for worms. I would make sure they also check for giardia and campylobacter as these are parasites/bacteria that commonly can cause similar issues but are difficult to diagnose. Lastly, i would get her started on some probiotics. I like ones made by vetriscience and Thorne. I hope this helps and she starts to feel better.

I'm sorry that Prince has been having problems with diarrhea! I personally am not a fan at all of Blue Buffalo for a number of reasons, and many of my colleagues have seen dogs with GI problems from being fed Blue Buffalo. There are a couple of brands of dog food that I typically recommend which have canned food options such as Royal Canin, Hill's Science diet, Purina ProPlan, and Iams. I hope this helps :-)

I do not recommend Blue Buffalo diets at all. I think they are too rich, especially for a young puppy. Also Blue Buffalo does not follow AAFCO standards (nutritional guidelines). So, I don't think their food is properly balanced. All they do well is marketing. Just because it is expensive doesn't make it better. If I were you I would find another food that uses AAFCO guidelines. It will tell you on the bag where the nutritional information is. If you could call the shelter where you got her and ask what they were feeding that would be helpful. The other thing I would do is feed a probiotic as that will help repopulate the GI tract with good bacteria. Hope this helps! Best wishes!

I'm personally not a fan of Blue Buffalo. Their quality control is very poor because they don't own their own factories to make their food. They give the recipe to the factory who makes it for them. That means they aren't there to be sure the recipe is followed exactly. I would try Orijen or Acana. They own their own factories, so the quality control is very good.

Unfortunately, it is quite common for some dogs to experience GI upset ([vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) or [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/)) when switching food. As long as Bo is behaving normally otherwise, you may be able to [manage her at home](https://www.petcoach.co/article/6-things-you-can-do-at-home-if-your-pet-has-diarrhea). I recommend withholding food for 12-24 hours. Resume feeding a bland diet (boiled boneless/skinless chicken breast mixed with plain cooked white rice) in small, frequent amounts. Begin with 1 tablespoon of food every hour and gradually increase the amount as long as she doesn't vomit. Feed the bland diet until the stool is consistently normal (usually several days), then transition slowly to the new diet over another 5-7 days. [Veterinary probiotics](https://www.petcoach.co/article/probiotics-and-prebiotics-bacteria-aren-t-all-bad) may be considered to promote gut health. If she continues to vomit and have diarrhea, or develops lethargy, loss of appetite, or abdominal pain in spite of a bland diet, she will need to see a vet as soon as possible.
