I'll be super honest, I sat there and would try to stand over Nero to eat. He didn't get over 69lbs until after he was neutered. I found him exactly how
@Archer has found Belmont to be. Worried me to death forever.
Since he was neutered at 18 months, he has only been off his food once. Gulps it down so fast that now we stand over him telling him to slow down vs eat.
Coddling never worked either, trust me. I tried changing flavors, adding toppers, including canned food and even shredding cheese. It would work once or twice and back to meh... Just follow her advice. Put the food down and pick it back up. If he doesn't eat, he doesn't and hopefully he's hungry next meal. Make sure you have a high calorie food so that when he does eat, he's getting the calories he needs. (JMO.)
