I stay home most of the day and only leave for 3-4 hours at a time and when i get home Teddy is super happy and hyper fo rlike an hour. BUt he settles down and sleeps for a big part of the day (he's sleeping right now!) I dont think you have a problem. Maybe u can try playing fetch with him or something but while i cook and clean he will just sit by me and watch me. I think thats pretty normal. As long as someone comes to see him mid-day i dont think he should feel too lonely, some dogs stay home alone for 8 hours or more. I think he should be fine especially that hes still a puppy and will sleep a lot.
