I am still anxious to hear your responce to the two pound dog. I cannot picture you picking up dogs and continue walking the others, unless they fit in your pocket. I would probably bring a baby stroller for the ones that get tired out, (they do make something just for dogs) but it is admirable the time you give your dogs! They must sleep good at night.
I have two small dogs and they get there walk, off road or side walk. They do not really walk, more like sniffing this and that and though we really do not cover much distance, they are still quite tuckered out. So I feel distance is not as important as the fresh air and the sniffing part

Well, I rarely ever walk my dogs by myself and if I have to walk by myself I only do two at a time. If I am taking all four out I have someone with me and they walk two and I walk two ( one big one and one small one) so if one little one gets tired we just pick one of them up and still walk the other one. They are light and not hard to carry in one hand. I do have a Jeep Dog Jogging Stroller that I use sometimes and an Outward Hound pet carrier backpack that they like to ride in. They can pop their little heads out and still look around and even when they aren't walking they enjoy being outside.
I do agree with you, I don't think distance is a huge deal, I mainly go as long as I do so I can get my evening work out in as well...sort of gets two tasks done at once
I must say you excercise your dogs a lot more than most people, kudos to you! You're healthier & happier and so are your dogs (lucky babies you have).
I have two Weimaraners and for many years now I let them run off leash in 8 acres of open field once a day for anywhere from 25-45 mins. We live in Minnesota so when the weather gets bad (below 25 degrees) we sadly don't go out.They love running and stay close by me and are good on recall. We throw frisbee and kongs and they have a blast exploring. We rarely take actual "walks" since they prefer to run. But yes, we do this everyday weather permitting.
The sad thing is I am the only one on my block that excercise my dogs! Everybody else NEVER walks theirs... pretty sad IMO.
If I had to guess the average walk time for most people would be half an hour a day, most days of the week...??
That is so neat that you can let your dogs run off leash! I wish there was a place like that around here, the only place I have like that is my fenced backyard and it's no where near 8 acres.
It gets pretty cold here in the winter time as well and we don't walk as much then either as mine get cold pretty quick (even with clothes on)
It also gets super hot here in the summer and we normally have to either walk in the evenings when it's cooler or sometimes I'll let them swim in the pool for their exercise instead of going for a walk.
May-January we hit the dog park almost daily (atleast 6 days a week) which is for about 2 hours, or somtimes even up to 5 or 6 depending on the weather and my scheduele 9which is pretty easy going), of hiking, swimming, playing with his buddies.
then we do normally 2 other walks during the day for about 45 mins. just becuase I like to walk and like the outdoors. he doesnt need the extra walks, but why not he enjoys them.
January-May. (becuase i work 2 jobs at this time of the year. and it gets dark so quickly) we go to the dog park mys cheduel permiting about 3 days a week. and then just do normal walks daily if no dog park, I take himt o the school field to run and play ball.
Rain, snow, -30, +30 we are out and excersising. Weather doesnt bother him. And he needs his walks.
I try and get him out of the house as much as possible. even if it means my mom is driving to the gas station she grabs himand he goes int he car lol.
ETA: Blaze is a almost 6 year old Male rough collie (maybe some sheltie in there too)
That is awesome how much exercise your dog gets! It's great that he doesn't care about the weather either...unfortunately, I cannot say the same for mine...if it's even the slightest bit drizzling they won't step foot outside, I'll open the back door and they look at me like "are you crazy?!

" and when it's cold outside they don't really care to go out much either, they'd rather sleep in their beds all day....lazy things!
