Tink was very lightweight at 2.5 years old (9 pounds). The Hill's Prescription L/D has a higher fat content but lower % protein than regular foods. I'm guessing any Hepatic diet would be higher in fat, as the liver needs the fat to do it's work. The protein is more easily digestable too, and this combination will help the pup to put on some weight, as his body will be able to process and use the food easier as it was developed specifically for dogs with problem livers.
You can always call your vet back to verify any instructions given during a visit or over the phone. I usually leave a message for the vet to call me back when they have time, and I tell the receptionist or technician exactly what I need to discuss, so the vet can be prepared before they get on the phone with me. |
