Puppy routine and independence training

Hi everyone, I’d love some guidance on routine and early independence training.

I’ve read similar topics but still feel unsure, and I’m worried that our current routine might lead to separation issues. My puppy is a 16-week-old Whippet (a breed already prone to separation anxiety), and I want to set her up well.

She sleeps and naps in her crate without any whining, so that part is working great. The challenge is everything outside of sleep: she is with me all the time. I take her to work, she free-roams at home, and we go for walks together. Because of that, I don’t really know what a healthy daily structure should look like.

I’d really appreciate advice on two things:

1. What should a balanced daily routine look like?

• How much time should I spend on training sessions per day at this age?
• How much active play together is ideal?
• And how much time should she spend entertaining herself (chews, toys, sniffing, etc.)?

2. How to start leaving her alone?

This is the biggest uncertainty for me.

Should I begin leaving the house when she’s asleep in the crate and just gradually increase the duration?

Or should I only leave when she’s awake?

How much exercise or mental stimulation should she get before I leave her alone?

Any tips, step-by-step routines, or examples of what works for your puppies would be super helpful.

Thanks so much!
