He’s 18 weeks old, I’ve been testing him for weeks and he’s absolutely fine (I’ve been building up the time and filming him while I’m out). Mil has been with him all day and is leaving him in 10 mins. I’ll be home at 4 so 2 hours in total. DH walked him before work and mil walked him when he woke from his morning kip. I’m so nervous though! He’ll be fine won’t he?!
