Honey & Isabel
Honey was 6 months when she was spayed. I brought her home the same day - she had a dressing on her wound. Chicken and rice was on the menu - just small meals a few times a day for a few days until back to normal food. No exercise or play for first couple of days then small walks on the lead - just so that she didn't split stiches. Defo no swimming either. She was back to herself after a few days and I just gradually built up the exercise. Your pup will be fine and I do think the measures your vet said are a bit extreme especially the feeding regime.
