i wouldnt say at 6,5 months it is bright having her on the lamp she's still a pup but to what your saying my whippet i used to have would pick up anything birds or whatever and eat them but once she was 9/10 months and had her first kill she just pinned it and returned it into me . alot of people like with ferrets dont feed there dogs before they take them out but i feed mine in the morning so dont change my routine , with a pup at 6.5 months if its realy hungry i can see why it would eat the rabbit . apart from that only thing i can see that can be done is correct the pup every time she start
