I would say that if in your heart of hearts you feel you dont have that bond then re-home her as they pick up on these things.
Rescues arent bad things most have foster homes for certain breeds.

I do not have the relationship with my current dog that I had with my first dog.

My first dog was brilliant at recall but she was frightened of children. I loved her nonetheless.
My current dog is like yours - no recall if there's an interesting smell to be had. But, she loves every person . I love her nonetheless.

Both within their own confines I do believe had the most enjoyable life possible with us.

Do you love her? Accept she's different from your others and give her the best life you can.

Only you can know if that's with you.

Oh yes! Or rushing about making squeaking noises! Or hiding in the long grass!
Have you tried learning through play? So when your dog comes back her reward is a game?

I can totally sympathise with you, Fred can be soooo testing at times and he's 3 next month. He is brilliant every other way but once he gets his @rsey head on, he will just run and run and there's no getting him back. He's kept on his flexi lead a lot more than Mya is. I've found (and I'm no expert but this has worked for me). Open spaces are a big no no for Fred, these are the places he will run off so if I can't trust him, I can't let him off. I used to be able to play frisbee with him and did this for well over a year but then he started running off with this and even with another frisbee in my hand, my best excited voice and his long line on I couldn't catch him. Final straw was when he ran through 5 fields and the last field had sheep in, I thought he was gonna get shot by the farmer, I was hysterical so after that he does not get let off in open spaces. I've found the canal and cycle track are much better and he's been so much better when I have let him off, I keep getting him on and off the lead (I do this with Mya too) and I've found treats (cheese strings) that he absolutely adores which helps loads, they only get these on off lead walks. Fred doesn't get let off every day and this seems to help him so he appreciates things more. I've also found that walking them on canal and cycle track has got Mya who loves everyone, dog, bird, leaf etc much more socialised.
Please don't give up. If you don't feel confident letting your dog off lead then a good walk with the flexi lead on is great. I used to feel so guilty but honestly there are dogs near me that are lucky to get walked once a week.
Big hugs to you too xxx
Edited to say I've started whistle training too, Mya responds to this better than fred though (typical)!!

Teagan is 5, and still has rubbish recall!
We've been to training as a pup, and we go weekly now, and it's made no difference.
We still have fun walks, but she stays on lead all the time

I really appreciate everyone's thoughts on this. It has been a relief just to say how I feel and and find out how supportive you all are. Thank you.
I don't have to make a decision immediately and will try looking again for help with this problem.
Joedee I will pm you to ask if you can recommend a trainer in this area.

That's exactly how she is but unfortunately haven't yet found a magic food!

That does rather put it into perspective.

We have real problems with Ruf and his recall and so I totally sympathise - it is awful and walks can become really stressful.* I went through a phase of walking at quiet times and practising recall then - as I posted before this just led to him bolting the minute he was let off lead and disappearing for any amount of time really.* In my last training session the trainer suggested that the total lack of distraction was almost the problem and suggested that I be a bit braver and walk him at busier times and with other people.* I have to say bizarrely it has made a bit of a difference - we hooked up with some friends with* some dogs at the weekend and whilst Ruf wasn't playing with the other dogs all the time, he didn't disappear once and his recall was spot on.* Even with the huge distraction of a seemingly ownerless Jack Russell and lone walkers (!) he still walked with us and didn't bolt off once.* We also go on regular group walks where his recall has always been 100%.* So you may find that walking in a group, either with other dogs, or just with walkers might help.* Just a thought - it seems to be working with us...for the moment - no doubt in a few weeks I'll be back on here saying Ruf's recall is still a problem!

I can't see what the problem is either really. I have 2 dogs I can't just let off the lead.
Milo because he suffers selective deafness and couldn't care less if I walked off 50 miles away and left him, so he is exercised on a flexi. He is small though so not really a problem for him and Shady (a very large dog)who is fear aggresive to other dogs. She has a good recall (unless she sees a cat) but its the other dogs who don't who are the problem so I keep her on lead in public places so she can't be blamed for not being under control.
However for Shady I hire a large field at a greyhound kennels which is completely fenced in so she can have a good free run and play frisbee at least twice a week.
I would never dream of rehoming either, although have had my down moments with Shadys sheer strength and problems she has which are numerous.
At the end of the day though I took on these dogs to give them the best i could and yes I would love to have a relaxing walk with them both running free, but at least they get walked and well cared for which is more than many dogs do.
If you and your dog clash personality wise then maybe then rehoming would be the best as your dog will know how you feel and thats not fair.
But if its just the walking on a lead then as long as your dog gets walked it doesn't really matter.
