having trouble getting dog to settle at night

Hello! I adopted my sweet boy, Russell about four

months ago. I think he’s just hit one year. He’s really sweet and rambunctious fellow but is food motivated. He’s some sort of greyhound collie mix and is 60lbs.

The last 6 weeks i’ve been struggling with bedtime. I’ll go through my routine because i feel as if i really am giving him enough exercise and mental stimulation. He’s my first dog, so not sure if this is just normal for his age, or if there is anything better i can do for him.

Weekday:

We get up between 6am and 6:30. i get up and get ready for the day and make coffee. He gets fed 2 cups of food then we go on our 45-50 min walk which includes a sniff around at the dog park. We come back I finish getting ready for work and I head out the door at 8:15am. He gets a kong with a treat and PB in his crate when i leave.

I come back at lunch and let him out for a 10-15 min walk and potty break then he’s back in the crate with a PB kong.

I get home from work about 5-5:30. He gets fed and then we either go on an hour long walk or go to the dog park for an hour.

In the evening we play, he chews on a treat while I make dinner, and we do training sessions.

The issue i’m having is about 9-9:30pm when i’m ready for bed I can’t get him to settle. We potty before bed i turn off all the lights and tell him to go to bed, where he gets up on my bed and i give him a treat. I have a sound machine on as well.

Am i just being unrealistic regarding how much more exercise and stimulation he needs? He will bark and pace in my room before he will get up on the bed, anywhere from 5-15 min. i ignore him if i know he doesn’t need to go outside.

i was not having this issue until about 6 weeks ago and our routine has not changed.

Any advice would be appreciated!
