What dogs are in your neighborhood?
Do you tend to see a variety of breeds, or is one or another breed more common?
On our street, we have two pug/beagle mixes in different houses, a Lab/dane mix, a pair of Wheatens that just moved here, a little white Riley - I think he's a Lhasa Apso, and larger black Riley - a maybe Lab/Golden mix - her coat is like a Flat Coat retriever, but her size and build is closer to a Golden. So no real pattern ...
We see lots of kinds of dogs being walked over on Commonwealth Ave., too many to count.
