i want a companion dog that will be very energetic,playfull and not too big
i have a one family/flat house with large backyard
i was a dog breeded so i know pretty much everythign about care,training and owning a dog
i bred giant dogs ( newfies and giant schnauzers)
i did my research yesterday and im thinking about one of those breeds :
mini aussie( australian shepherd)
sheltie
greyhound
or american eskimo dog
i no nothign about those dogs besides what i have read
i need more information before making any decision
what i need to know is:
exercise requirements
grooming ( i know that long hair dogs need lots of brushing from past experience with nefoundlands)
and im willing ot take the dog out like 3 tiems a day for 1 hour long walks
will that be enough???

Medium Size Sporty Dog Breeds That Would Suit A Small House?

I’m a long way away from getting a dog but I’m thinking about it in the future. I’m moving to a flat (apartment), it is two level but still pretty small. I’m not really keen on small foo foo dogs or terriers, other half doesnt like greyhound-type dogs or lab/golden retrievers. Have lived with springer and cocker spaniels all my life, adore them but would like to try a different breed if possible. Cross breeds are fine too, I plan to check out the local shelters. Basically I would like a dog thats up to medium size, easy to train, that I can do agility with and exercise 1 and a half to 2 hours a day. I love collies, but dont think its really fair to keep them in a flat. Also like Duck Tollers, but not sure if they would settle in a flat…basically I need a dog that, although it is active, will be reasonably calm around the house, and not bark loads (afraid of annoying neighbours).
I’m very demanding aren’t I?
