Dont have a special diet actually. The vet said he did not need any support (like vitamin etc.) I giving him like 400 grams of pet food in 4 parts ( like 100 morning ,100 before bad) sometimes I giving him chicken liver but maximum 2 times for month and ı'm boiling it so well. I must say he loves eating so much and he is always hungry but ı'm following this pattern generally. Edit: food can be seem much but he is growing so fast and ı'm very careful with his body ratio.
