Our piggie Carlo recently had dental surgery and lost some weight because the problems his teeth were causing him. The vets advised us to keep an eye on his weight (which we have been) and not to be concerned as long as he’s maintaining but she’d ideally like to see him gain a bit back. I saw plain oats were a good way of helping them gain weight so i’ve bought some but i’m unsure of how much/how often I should be giving them to him?
