No dog should be pulling up at fences,especially bull crosses,have had them all my life an never had one do it.
Mate has a bitch there he bred,25tts salukibullgrey,she put away 30 foxes single last year an I seen about 25 of them,she missed a few too
Pleasure to hunt with,excellent bitch on the lamp,iv seen her catch the foxes that don't want to come sitting at bottom of big fields,just slip her in the dark an knock lamp on shortly after an she's next to it,great wee bitch
