how many times do we hear, the dogs walked. and still only young. more terriers ruined through putting to much in front of them. and not 2 year old yet. says it all realy. i had a bitch, park bred, she walked at 4 year old. start to a season, no intrest in her at all. 6 or so month down the line, took her out last chance realy. peged her out .entered another young inexperienced dog couldent find its quarry, so let the older bitch of the couple. bang. a result. the bitch was killed doing her job 5 years later. its not always the dogs to blame,
