My Labrador (9 months) will need to be left alone for most of the day on Friday next week as I go for a scheduled c-section. Luckily we are able to arrange his 'training trek' he usually has to that day which usually lasts 2 hours so that'll break up the day a bit. We are leaving at about 6:30am, the trek will last around 2 hours and starts sometime between 10am and 12pm then he'll be alone until DH comes home from the hospital, we don't know what time that'll be but should be before his dinner time at 6pm, if not we'll have to get someone to come and feed him. He's house trained and NEVER goes in the house anymore but of course we're usually there to let him out in the garden during the day so hopefully DH doesn't come home to any accidents!
Anyway I'm wondering if anyone has any tips to keep him occupied while we're gone? He's generally not an anxious dog and copes well being left alone when we go out shopping for a couple hours but this will be the longest amount of time he's been left so I'm not sure how he'll feel about it! He'll also be confined to our kitchen, lounge and conservatory as we don't yet trust him alone with our indoor cat 
I was thinking I could get him one of those antlers which seem to last a while. Probably worrying too much to be honest
