There seems to be a lot of emphasis on the various "breeds"of working terrier on thl but at the end of the day aren't they all the same animal .The way i look at it the two main performance bred breeds 'pitbulls and greyhounds'jmo dont bite my head off..were bred entirely for what they could do and the result is a variety of sizes and colours,admittedly different lines threw different types but were still the same breed with a same basic type So how did we end up with borders,lakelands,patterdales,russells,bedlingtonsinterested to see other peoples views on this..
