That comment referred to the age of the pups we are discussing here (8 month olds and older) in relation to the amount of food that the dogs are fed. The bags recommend too much food for a lot of dogs out there, particularly those owned by people who are either sedentary or absent during the day (so the dogs are sleeping 8-12 hours a day).But I was confused by your last two statements above...I know that puppies bones are soft and the joints are not even 'seated' for a few weeks. Until this happens exercise should be limited. Like you say low to medium is best with young dogs. Then you seem to contradict that and say "mine go 2-3 mile every day"...because they are high energy dogs!
I am sure I am misunderstanding your comments, please clarify if you will?
8+ month old pups = different conversation than 8 week old pups.
Young puppies don't go for walks. In fact, the longest walks I typically do with a baby pup is up the road and back home, which a month later gets extended to a 1/4 mile walk (very short 15 minute walk). A month later we might start working up to a 1/2 mile, etc....
Normally I'd stay under a mile for a growing dog - but mine are high energy and very powerful dogs. You go by the dog you own.
Personally speaking they do more harm ramming into each other while running outside on those days I skip a walk.... we had frigid temps the past weekend and uh.... no walks = my dogs tearing it up outside (and thank goodness they have room to run). My 7 year old got a much needed laser treatment this morning to get some inflammation in his shoulder/neck area down after he got double teamed by his sons. >.< He goes back next Tuesday for a 2nd treatment and if needed will get a 3rd treatment the following week.
*And taking a 2 mile walk is about 30-45 minute relaxed walk. It's not jogging and or heavy exercise for the dogs - especially young dogs.
