Thanks everyone for your response.
@persephone I went through your response earlier and I do agree, I do love animals but I don't like to have that over attachments. Gave me a hope if I do get slightly grown up puppy (older) we should be fine.
@Dogsfevr thanks again, we live a active life, we go biking not like 60 or 100 kms but just a short distance usually mtb and wanted to take dogs with us . Someone at my work told me
Blue Heelers : are active and run with you when you go for a bike ride or something, very loyal and easy to train and stronger
Beagles : because they are active and easy to train, heard they are hyperactive and leaving them alone is not so good.
PWD : is sort of size I was looking for still active dog.
I want mid size dog ( I live in suburban area) , active , friendly, good with kids and other dogs, prefer shed less and easy to train. I do want them inside but not always so need dogs that I can leave outside in yard for a period of time. what are other dog breed should I consider ? any suggestion would be good .
@Tassie thanks I am planning to visit some dog show in Melbourne, I have been asking dog owners. Setting up my backyard , sides with dog on my mind . As said I maybe able to get someone to check puppy during the day for first month or two. Also thinking of getting a older puppy, would that be hard to train ?
