9 month old pup. He was fine using garden until he was about 4/5 months .....and now he won't at all. We stand outside every night when we go to bed and say 'wee wee' ....he used to always go. Now he runs off under bush/plays/walks around and I just leave him to it for 10 mins - I can't see if he's been or not. He is created overnight - sleeps perfectly (no accidents since he was about 12 weeks) and is happy in crate until we get up. He's let into garden as soon as we're up - but he doesn't go. He has a walk before breakfast - he does several wees (and seems to do lots of leg cocking just for fun). We're WFH so he has early morning walk, a little 'poo walk' a couple of hours after breakfast and then a big evening walk (or a big lunchtime walk and a quick 'poo walk' post tea). However, when it's so hot in the day, we don't take him for a daytime walk.... he's been in the garden on and off a day - but I've not seen him go to the loo at all. He seems perfectly happy and he's obviously got a bladder of steel!....I'm just a little bit worried in case he's uncomfortable (surely if he was he would go in garden?!) or in case holding it for so long is bad for him/causing any damage??!! Thanks
