Preferably weekends. Anytime before dark (before 4pm). They’re both good with other dogs but need to be walked just together as the lab x collie is temperamental and is very strong, we usually have to walk him with two leads or around a field as his energy levels are high. I also want to note that we usually walk them both with two people just to be cautious. Our puppy has recently started walks and loves them, he goes with the lab and can handle the same duration and is fine with a harness.
