Quote:He usually gets plenty of exercise daily as he can roam and play in a large yard with kids and my other dog, plus his walks but maybe he needs a walk in the evening after dinner now that he is older.
It sounds like he needs more structured exercise. Having a large yard and another dog are great, but unless he has a toy he's really into (my Ronja loves pushing a soccer ball around with her nose and will do that for hours!), being out there and playing with him, tossing a ball or frisbee and having him bring them back, would give him better exercise.
Now that he's older, your leashed walks may need to be longer or faster for him to get good exercise. You may need to add another walk if necessary.
Also, don't forget the mental exercise. Do you practice your basic commands (sit, down, stay, etc.) everyday, throughout the day? Do you work on new things? Do you play any games where he needs to use his head, like hiding treats for him to play?

You may need to buy a bigger crate.
I have two big VariKennels in my kitchen where both of my girls are crated when we are not home and while we are sleeping. They're also fed in their crates and we use them when we travel. IMHO you should always have a crate that your dog fits into, in case it's needed - both for crating in the home and emergency situations (to the vet, having to travel, etc.)
