I’ve got it in my head that I’m being neglectful and I need advice

Title.

Please be kind – I need to know if I'm overthinking… I wasn't sure what to tag this as.

I'm a teacher. My contract hours are 7:30-4 pm. When I got a puppy this summer, I decided to sign her up for daycare. She LOVES daycare and the staff LOVE her. When we walk through the doors, I no longer exist until pickup around 4 pm.

She gets a big breakfast at home. I always pack her a lunch and she always eats most of it. And she gets dinner too once we get home. Sometimes I have meetings after work or just things I need to get done so she won't get picked up until 5 or so. And I always feel awful.

Today they're doing a little happy hour after work and for some reason, I feel like I am neglecting my puppy if I keep her there until 6 pm. 11 hours is a really long day for an 8 month old, right?

I just need Reddit to tell me that I'm being ridiculous because that's how I feel haha

Edit: I feel like it needs to be said that my puppy goes to daycare on and off. Sometimes one day per week. Sometimes two days per week. On other days, we do 2-3 walks. We also have playdates with 3 different dog friends pretty regularly, and we're in puppy school as well. So she's got a full schedule and we do everything together.

This isn't a situation where ALL she does is go to daycare and I don't even interact with her. She's the best thing to ever happen to me and she's completely changed my life
