Do you take your dog on the same walk each day? Is that because you just like that walk or there is limited walking places for dogs in your area? Or have you a few places you go to? Do you think it makes a difference or that it doesn't really matter as long as they are getting that exercise? I took my dog to a new area yesterday and he was totally not interested in anything around him. 50 dogs could have passed and he would have ignored them!! He just wanted to sniff and run about the new interesting ground!
