daifuku got FAT lol

Vet weighed Daifuku last week and he is 12.8kg. Vet said ideal for a shiba his size is around 9.5. So we are in trouble. He is 7 and half and still eat like a puppy lol. Vet gave us diet food and said no more chicken skin, no bread, no rice from our dinner. Mom still feed him secretly tho, I saw her give him a whole shrimp cracker last night. She says he looks sad when we dont give. We started a walk every morning around the soi, 20 min, he is so slow and sniffs every tree and every pole. I think its fine. He recieve his treat only after the walk now. Its working alot better than the diet food alone, honestly. Doctor said he need to lose about 1 kg per month, not faster or it is dangerous for his joints definately. So its gonna be a long project.
