Hi, I've owned dogs my whole life (soft spot for black labs) and now work from home so have the capacity to help out some other dog owners.
My 2 year old pup scout (labrador) is at home with me and loves the company of all dogs big or small. I'll walk your dog with mine if that works for you - we usually go first thing in morning, short lunchtime walk and again at 4pmish. My apartment has a small courtyard on the ground floor fully enclosed....
