My 1/2x bitch is the runt of litter she is 23tts & made good,me & my mother hand reared her as she was not suckling tidy but she's 6yr old now & never let me down she's game as they come she never takes step back she gives 110% every time & doesn't make a murmur when taking stuff with teeth,so from my experience I can't fault a runt!!!
