I am glad you took her in and that the vet helped her feel better. That Cerenia, an anti nausea shot, is magic!
Our pup is good, knock wood. I feel like we are early in the journey but hopefully with diet control we can keep this regulated. With Boxers, it is always good news to have a condition you can do something about. So often their diagnoses are terminal… We were definitely at fault with plenty of high fat treats prior to his first serious bout. My guy loves our dogs and liked to indulge them with people food. He used to do spray whip from the can, cheese, peanut butter, etc. To his credit, the minute our Boxer came home, he stopped giving people food cold turkey.
I have found a few treats that are super low fat. My guy and I also take turns following this recipe for homemade treats using his Hill’s ID Low Fat. We do the kibble version. Throw some in a blender to make powder, then add water to make drop cookies. Very easy but it does make the kitchen reek!

My dog’s first trip to ER was in April. We did only the Hill’s diet and homemade treats for the first two months. Then every two weeks we would introduce a new low fat treat. Keep in mind, our Boxer is 60 lbs so a few biscuits is nothing to him compared to a mini poodle. We have been able to provide these treats in very moderate amounts

about 3% fat

about 6% - we get the mini treats and I ration out how many he can have each day.
We have also added freeze dried chicken breast which is pretty low fat, too. I am crazy about reading labels now. What I don’t love is that dog food and treats lists minimum fat content but not maximum. I always figure the manufacturers aren’t going to make it even fattier than it lists because adding fat adds cost to production.
Hope your girl continues to improve. They are our families!
