RE: looking for a new dog maybe a German S.H.P.
I have a 3 yr DK and she is a great dog. She is great with my 10 month old son he climbs all over her and pulls her ears, wiskers and tail and has never got aggressive. I think she enjoys the attention she gets from him climbing on her.
I let my dog out off the leash all the time I think that is more a training issue then the type of dog. You bond and work with your dog they will listen to you.
Now ,these are dogs that have a lot of energy, they need to be ran. A 30 minute walk on a leash will not do anything for this dog they need to run. If they don't get enough exercise they tend to get bored and can become distructive. This is a problem with a lot of hunt breeds.
I would recommend this breed to anyone as long as you have time to spend with and exercise the dog. They don't do as well as a Lab at becoming a couch potato. ( I am not picking on Labs I have owned them before also they just aren't as wired as a G.S.P)
