Can anybody offer some advice regarding when it's ok to take our puppy outdoors? Mikko is 9.5 weeks old, and very energetic so he needs a lot of exercise! We play with him in the house a lot, but the space is limited and we like to take him outside in the yard to run around as well. My concerns are that we have an unfenced yard (townhome, with front yard only), and although we watch Mikko very carefully, I don't know what other neighborhood dogs are doing their "business" in our yard... so I'm concerned about him contracting some disease from an unvaccinated dog pooping on our lawn! We keep our lawn picked up and I've never seen any foreign dog poo on the premises. So... is it really realistic to keep Mikko totally indoors until he has all of his shots? Are we taking a big risk by having him play in our yard? Also, we have been taking him for short walks, just down to the end of the block, to get him accustomed to the leash, and for the exercise of course. We do not allow him to go on any grass, as I'm worried about him coming in contact with other dog's "business". Do you all think this would be ok since we keep him on the concrete, or is this still too risky? I don't want to jeopardize his health, but want to be sure he gets enough exercise as well... Thanks for any help you can offer!
