A dog
food prescription diet, also called a «therapeutic» diet, is only available through your veterinarian and is used to treat a specific disease or disorder.
You'll know you're looking at a dog
food prescription product if the label explicitly states that it must be prescribed by a veterinarian.
The dog
food prescription diet was born almost 70 years ago when a veterinarian named Mark Morris, Sr. decided to change a sick dog's diet instead of prescribing medication.The patient had a form of kidney disease, so Mr. Morris simply created a diet that would go easy on the dog's kidneys.
