Hey guys,My 3 y.0 EM atta and i are getting into biking this spring/summer. Right now i have my rooommates bike indoors just so atta can relate to bikes because it is still winter here in Canada. I have got her a custom made harness and now im just doing research on my next purchases 1. The bike itself and 2. the attachment of either springer or walkydog. the style of biking is just causal cruising inner city and at the lake no intense cliff climbing etc. Just want my dog to be exercised well as the dog park is now not an option for us and leashed walks don't hardly seem to cut it ! Any input on bikes and attachments please comment !
