Hyper dogs

We have a german shephard cross and he is about 3 years old we got him september last year so havent had him long, he was badly neglected and can be very hyper he needs a lot of exercise and even then he can still be hyper and under my feet! He barks at neighbours anyone walking past the window i dont mind that but when on a leash the only time he barks is at tall dark haired men at the same time he will be slinking behind me tail between his legs because he is just so scared of tall dark haired men. He whines and yelps a lot when walking on a leash mostly i think because he prefers to be off it and having a good run in the field but i dont have time to do that every day so he has to settle for a couple of long walks instead!

I know a couple of dogs who are pretty hyper. My friend has a pet pug and the dog just won't stop playing with the guests! Haha. I love that pug. He's adorable, to say the least. Another friend has a Shih Tzu and it's pretty hyper as well.

Ours do it too, They don't bark at strangers approaching the house, of course. But let a cat (that they know) or a bird land, they can bark their heads off. They're letting us know they're on the job. Now we're supposed to give them a treat.

I used to have a couple dogs like that - I just stopped taking them our or for walks after a while, it got pretty annoying. It's more common in smaller breeds, and they'll tend to bark at anyone or anything they see, especially other dogs.
