thanks for the replies. i have a straight bedlington whos 19.5'' tts so a big dog at ten months dont reckon he'll grow much more. And i believe the more time put in the more you get out,he is quick enough to take a rabbit on the run imho.he retrieves,stays till sent to pick up the rabbit skin dummy and surpisingly soft mouthed.im only a lad so this is mu first dog,hes a joy to own and couldnt ask for much more,use to be terrible at recall when younger though,but spent time on it and turned out great.
