Mate my Wheaton x bitch is 27 tts and 80/90 lb fighting weight...had her out ferreting from first jabs with longnets etc,around the harris/gos hawks, she's done everything you would use a whippet/smaller dog for,she loves the deer,that's what she's mostly used for,she comes out ratting,on the moles with me, people have told me she only be good for one thing...she runs forest blocks,hills,even been down on the chalk/flint and put plenty to bed,I believe you expose a dog to as much as you can,as young as you can,giving them the opportunity to pick it all up,they learn when to use their speed, s
