Is 3 hrs walk a day enough?

Hi again, now I'm alone with Debo, I have to do everything to male him happy. He's over 2 now. And our routine looks like that:
5.50 - wake up/meal
6.20- walk, 40 min with ball/frisbee
1pm - I'm back from work and we go for an hour walk ball/frisbee
5pm - meal
6pm - 1 hour walk
Between walks we play tug of war, ball, a bit of training ( we do training on walks as well ).
Is that enough to keep him happy?
By the way, he's daddy's gone to UK, and I do everything I can to make DEbo not to thing about him. It's better then I thought.

Sounds perfect - and it is hard having a dog o your own. Notlong now and you will be back Xx

It's very hard, it's been only 3 days and I'm tired already but at least he takes my mind of thiking how lonely I am. I can feel we bonding now.

Sounds perfect Hun, I'm sure you'll both comfort each other until daddy, you and debo are back together in Ireland xx

Never be lonely, come and chat x

Hayley, it will be Swindon, don't ask me why, never been there.
Janey, I know I can count on you guys.

I think that routine is just fine   

Like janey says, if you ever feel lonely just drop in here and have a chat   

The meal when waking up, is this for you or Debo ? Ideally a gap should be left between exercise and meals of at least an hour for a dog.

Kathy, is for both of us. I know but have no choice, otherwise he will it his first meal at 2 .

What time do you leave for work, could you not leave his meal until then ?

I have to leave at 7.15, I'm worried that he won't be able to hold it, don't want to stress him out.
