best dog for going for long walks

Question
I want to get a dog that loves going for long walks & for long bike rides.  Any suggestions?

Answer
I think almost any of the larger breeds should do.  www.akc.org and www.purina.com have breed selector pages on their site.  You might try them.   Don't take a recommendation for some obscure, hard to find breed too seriously. Even if your puppy doesn't grow up like you expected, how you raise it helps make it what you need.  The first 12 weeks of a dog's life greatly affect its adult personality.  Expose it to your lifestyle, and it will be comfortable with you.   Gretchen, our one German Shepherd did not grow up suspicious of strangers.  She knew no other life except being out and petted by strangers from the night we picked her up at 7 weeks old.  After she was a year old, the dog guide school chose to retain her as breeding stock.  

While a fairly young puppy can go on long walks, a dog should be at least a year, and perhaps 2 years old before running along with a bike.  Yoou might consider getting an older dog.  

One of the best sources for dogs with a predictable personality is the rescue dogs.  These are dogs that lost their home, but were taken into a foster home to be retrained as necessary and placed in the right home for them.  You may find a rescue near you starting at http://www.akc.org/breeds/rescue.cfm  The rescues charge a fee to help cover their expenses, but is much less than the price of a puppy plus all its medical expenses the first year.
