Thanks everyone. I don't think half check collars are right for us. I was just surprised the trainer recommended them. Your replies have made me question even more whether the course is right for us. Its run by a charity and is very popular, huge waiting list. Maybe because it is so cheap - £20 for 14 weeks! We live in Harrogate. Don't suppose anyone knows any good classes in our area? I'll probably go along anyway if I can't find any more - and if I don't like their methods - won't use them!
Lela's recall is generally very good, unless she sees a bird
and she is very well behaved otherwise. She does pull on the lead though. So not sure how much training we need? But it would be great fun for her (and me!) I guess.
