Hi I was wondering if anyone else had this problem as my 6 month old Border won't wee when he is on his leads going for walks around the block where i live and will only do it off the lead when we take him for a wee in the woods (which is a couple of miles away otherwise i'd take him there every day!). I tried to tell him to wee wee last night on our walk on a patch of grass but he wouldn't! He held it till he got home and then i took him on the grass in our back garden and he still wouldn't do it with the lead on - just kept looking at me & tugging away from the lead thinking i'd took him off it! So i took him off and he walked up the lawn & weed! :? Does anyone think he will grow out of this or do you think he has a problem?!! Thank you!
