How would've a 17 inch bull/ whippet been handy pre ban? obviously she isn't going to take deer and I haven't got any round here anyway Shes quicker than she looks and has loads of prey drive and a good jaw so I don't think foxs would be a problem the fields round me arn't particularly big and I hunt a lot of rough ground and woodland a big dog would be no good for the land I run . Hope this answers your question
