Naturally I'd want to know how reactive your dog is to others. I know lots of good walking spots for where I take a reactive dog to avoid conflict. Any allergies they may have. Do they have a dislike for certain things or people.

Every morning if the tide is out I take Nora on the beach as she likes to role in the sand and we make a game of 'mad dog' where she gets the zoomies. She's not much for one for balls but loves to jump the fences. Then later I take my mother's 3 dogs out, which consists of 2 shitzu and a labradoddle. One is rather elderly and doesn't walk well so dependent on how his legs are he may get his own slower paced walk so the others can be exercised properly. All are very well behaved and have great recall.
