G'day, we have just bought our first home and would like our first dog but are struggling to decide on a breed/cross-breed. We really like Border Collies, Kelpies, Australian Shepherds and Blue Heelers but I know they are traditionally working class dogs and I'm worried we may not have enough space. We live in a quiet suburb in south-east Queensland, on a 760m2 property, of which the back half is fenced at the moment. We've got two teens who will hopefully help keep it active and I work from home so will be around the dog and will be able to take it out/walk it. We're within easy distance of dog parks and 30min from a dog beach. Are any of those four breeds less active than the others, especially if crossed? Or maybe there are other types of dogs we should consider? We would prefer a dog that doesn't have a lot of hair and we don't want one that barks too much. Cheers.
