A friend I live with has a 5year old husky. he doesn't exercise him, so I do. the thing is, he's overweight. we live in california & him being 80lbs makes him hot & tired.
now that the weather is cooler, I want to make the most of our walks so I bought him a backpack. it fits well & he's gotten used to wearing it empty & I usually walk or run with him 1-3 miles a day. so now I need advice on how much weight he can carry; the maximum as well as how much I should start with & how to increase it.
my dog is a 13lb italian greyhound so a fat, fluffy, large dog is new territory for me. thanks!
