Spaniels. They are born with aggressive instinct to find birds, humans just teach them to bring the birds back. There are lots of dog clubs in Alberta who can recommend quality breeders, as not all dogs come from quality field stock. If you've never trained a dog before, join a club for the first year and attend the puppy training and retrieving lessons. Dog owners often need more lessons than the dog. Club memberships can be between 50 and 100 bucks, and they often gather weekly for lessons and trials.
Springer and Brittany spaniels make great house dogs, and only poorly bred dogs will ever bite or show their teeth to humans and more importantly , children. When at home, they are part of the furniture accessories, much like pillows, but out hunting, they are all business. When you invest into a good quality field dog, you are investing in a hunting partner that will never; let you down, be late, have a hang over, sleep in, nor cancel a hunting trip because someone's Mother is coming for a visit.
These Pups are no longer with me, but put birds onto the table for over a dozen years.
