Here is something i have been wondering.
How long is 'too long' of a walk for our B?
The wife and i like to do a nightly walk around the neighbourhood and we notice that around the 2km mark she starts getting tired (or bored). She isn't quite as attentive on leash and she starts rubbing her head on the ground and wanting to just roll on her back and rub herself. Generally a quick tug on the leash and telling her "We are almost home" will get her moving, but yesterday my wife had to physically pick her up and carry her for a bit.
Is this a sign of something wrong? Hip problems etc or are we just taking her for too long of a walk? In the house and backyard she has quick spurts of energy, but that is usually followed by a quick nap on the couch.
Is this Normal B behaviour?
