Hi all. [

] It's been a while since I posted on these boards. I really need some advice about leaving my 8 month old Shih Tzu at home while my fiance and I are working.
He's the sweetest little boy and we love him dearly. My fiance has been taking him everyday to his parent's house (since it's on his way to work) where they keep him in a playpen. His Mother comes home to walk both of the dogs around lunch time and my dog is able to at least see someone halfway through the day and he still can see the other dog from the playpen.
On Monday, my fiance decided that we should try leaving him home. I think it's too soon. We bought a WebCam so I could see what he does while I'm at work. I keep him in his PlayPen with all of his toys, water and food. For the most part on Monday, he slept. Today, he was more lively and he barked and cried for a few minutes mid-day and then went back to sleep.
My fiance thinks that I'm being overprotective saying that he needs to learn to adjust. I agree, but I still think my puppy is very immature and it's breaking my heart to see how sad he is. I leave my home at 7:50am the latest for work and I don't get home until 5pm. We both love our puppy but I think we're both looking at it from different angles. He loves him but he wants him to adjust and I do, too, but I think he might do better adjusting later. When we first brought him home, we had terrible issues with separation anxiety and he's been so much better since the months progressed. He no longer cries if I leave the room or if I leave to go shopping for an hour or two.
If anyone has some insight, I'd really appreciate it so my fiance and I could sit down and have a heart-to-heart talk about this tonight. Neither of us are experts so perhaps some objective opinions might help.
Thank you so much for reading.
