Note-- I am not a vet
Has the vet done a urine culture test to make sure that the antibiotics are targeted correctly for the cause of the UTI?
Is the vet recommending a certain food because of urine crystals? For struvite bladder stones, a diet with restricted phos and magnesium is often recommend in conjunction with the antibiotics to help dissolve the stones. My understanding is that many times, eliminating the infection can mean the stones don't again become a problem and the dog can go back to a regular diet.
Is she spayed? If so, how old was she when she was spayed?
IMO, Blue Buffalo is crap. Overpriced and many dogs have digestive upsets on it. Heck, I once had a starving foster puppy refuse to eat it! And yes, she ate other food just fine when offered it so it wasn't a health issue causing lack of appetite.
At 1 year old and large but not giant breed, she doesn't need "puppy" food. You can pick a good All Life Stages food (which means it meets the standards for both adult maintenance and for growth and reproduction aka puppy food) or an adult food.
I'd look for a food with an ash content of under 7%. High ash content means more minerals for the dog to have to process out, there is indication that high ash like 9-10% is hard on the kidneys.
