You seem to be taking umbrage to my post charts . I was merely offering my opinion and my experience. Albeit 45 year of experience of running all sorts of soil and clay . As you will attest to , different soil and of course temperatures dictate the severity of nail bed injuries not to mention dog breeds . Again, you'd be far more knowledgeable than me with far more experience of deerhounds and their mixes . Lurchers and saluki hybrids being my thing . Once again, no offence intended whilst offering my opinion. It's all our opinions that keep this site going. Yours in sport Drover
