Questions Owners Ask
Where can I learn more?
A prescription diet is a treatment for a diagnosis: kidney disease, urinary stones, food allergy, or a gastrointestinal plan. The clinic should tell you which nutrient target matters. FDA and the manufacturer publish the indications. Switching back to the old food because the bag is cheaper undoes the treatment.
How often should I take my pet to the vet?
Kidney diets, urinary diets, and hydrolyzed diets are reviewed on the disease schedule the clinic sets, which can be a few weeks. The wellness layer under that is puppies and kittens every 3 to 4 weeks until about 16 weeks, adults about yearly, and many senior dogs from about 7 years, giant breeds earlier, and senior cats from about 10 about every six months. A pet who refuses the diet, loses weight on it, or vomits on it should be seen before the bag is swapped for a grocery brand. The prescription is for a diagnosis already made.
How can I save money on pet care?
Ask whether a therapeutic diet from a second company meets the same target if the first one is refused. Three bags a pet refuses are the loss. A recheck that says the diet can stop is the real savings. Stretching a urinary diet by mixing in the old food is how crystals come back.
