And what breed is it? 
I am curious to ask this question as i have a friend 
that tells me it costs him $20 per week per dog. the dogs 
get to run around free for about 1/2 hour to 1 hour 
per day. They are large lean breeds. He feeds them with 
dry food once a day (which stays in their bowls) and then 
1/2 each of those huge dog rolls once per day, and sometimes 
leftovers. The dogs are healthy and seem satisfied. 
i know cost depends on what you feed them and what 
breed of dog it is, but i am curious to compare this  
amount to what it costs other people to feed their 
dogs, what they feed them, how often, and what breed 
is your dog, and i guess how active are they?  
would love to hear any responses. thanks in advance.
