We live in a unit with a small backyard. Merri creek and Yarra parkland is literally 30 m from our unit. We do two walks a day, one being a longer one. I am home most days.
The visiting dog needs to be okay with kids (my daughter is 13) and preferably be desexed. It helps if they are not too bossy or boisterous, walk reasonably well on the lead and have good recall. I suggest we would always meet up for a walk together first. Gives us a chance to sniff each other out :-)
I grew up with dogs and have a strong common animal sense - I'm doing my PhD in environmental science which involves handling wildlife. Your dog will be part of my family and allowed on the couch, but only after I give the okay. I believe in affection, exercise and discipline as the corner stones for a happy pooch. Happy to provide some training, too.
