I dont really walk my dog in a sense on a leash beside my all the time. Majority of our daily "walks" are biking riding any where from 5-15km's a day. depending on how I feel, and if any one comes with me that day.
I believe every dog should be able to get out every day and stretch their legs, see differnt scenery, smell new things and do somthing exciting.
Aside from bike rides, we do the dog park atleast 5 times a week (havnt in about 2 weeks due to rain and now the pains in my stomache hurt to much for large offleash hikes. as soon as surgery is over, we will be back to them lol) he goes for car rides probably 1-2 times a day. play ball ect.
I try to keep him busy as he becomes very very VERY annoying if bored. Not that he destroys anything or miss behaves. just he follows you, right on your heels, so if you stop too soon, he crashs in to you lol.
I dont see anything wron with missing 1 or 2 days a week. I do it somtimes. and I make up for it with being annoyed the rest of the night lol.
He is easy to amuse. he was on my heels for the last 2 hours. So i tied him to the bike and just rode for 20mins. Now he is sleeping lol.
