How long should a daily walk be for a 9 month old WL puppy?
Starting Monday (Kody's in a kennel right now because my dad's away on a work trip) I'm going to start exercising my 9 month old puppy, Kody, more. On the weeks that I'm with my mom I'll only be able to walk him once a day and do one training session a day, so I was wondering how long each of these should be? I was planning on walking him around the neighborhood for a certain amount of time, then going to the neighborhood park, my backyard, and/or inside the house (depending on weather and where we are when it's been however long) to work on his obedience training. After that I'd sit in the family room with him and maybe watch an episode of something short like Scrubs (I'm a bit obsessed with Netflix) while playing with him, cuddling with him, or letting him chew on a bone or Kong, all depending on his energy level at that time.
So that's my basic plan. Sound good? Kody is an AKC, Working Line puppy with HIGH energy. The only time I've seen him tired out is when we get back from the dog park for a couple hours! The last time I weighed him he was 45 pounds, but it's been a couple months so I'm guessing he's around 55 now (mother was 65 and father was 75 or 80 I think). He eats a cup and a half in the morning and a cup and a half to two cups in the afternoon, plus an extra cup or so if we do some extra training. He seems to be at a good weight, but I'm always worried about him being too skinny. Do you think this is a good amount of food for him? Will I need to up it once I start walking him more?
And here's my main question: how long should the daily walk be? I've heard 40 minutes to an hour to two hours, and I was wondering what you guys think would be best for Kody based on his genetics, energy level, weight, and age. I also have asthma, so it's hard for me to exercise for too long, but I do have an inhaler, which helps some. Thanks for reading this super long post!!!
