i am picking up my new and first cavalier on sunday. He is three years old and due to the family having a rather difficult baby they are selling the dog. He has basically put on about 2 kilos of weight since they had their second child as they have not been able to look after him as well as they would have liked.
My question is i want to get him back down to his ideal weight as soon as possible and was wondering how quick/much you should diet a dog. I dont want to fast the dog etc
