How much time a day do you spend playing/entertaining/training your 9 months puppy?

My Norwich terrier is turning 9 months soon. She is rather active at home and also has some separation anxiety. I spend about 30-45min playing with her (including short training games) a day. I also walk her twice a day, 40-45min each time. She will spend about 4-5 hours hanging out around the humans. Rest of the time will be either in her playpen or we will try to go back to our rooms and leave her alone in the living room for a short period of time to try wean off her separation anxiety. I want to check how much time do you usually spend entertaining your pup at this age, and what is good so that she don’t develop an over reliance on us. Thanks!
