I had an Australian Shepherd for a goodly amount of time that was the sweetest dog but also the most protective… wonderful guy… recently got a Corgy as a gift that is only three months old and knows about 10 commands really well so far… also got another Aussie, a Blue Merle about a week ago that shows all signs of being the stupidest dog on the planet… all I care about in a dog is that they have brains that function…
