dogs are far more then a hobby lol they are flat out work if you want the dog to be a good dog.
my dog knew a load of words too. i could line up all his toys, tell him what i wanted and he would get it. then the long list of stupid pet tricks i taught him lol
the best part was i was able to turn him off in a second from full bore nuts, to play time is over. and his nose. i could have made money off his nose. i had him sniff out bags of weed at friends houses, hes like you'll never find my stash, oh, yeah, watch this crap lol he found both of his stashes lol my dog was nick named the nark after that lol he could find coke too.
by far the best mind f was my back yard had 8 yards of del river stone around the back side of my pool. i had one rock with his name on it with a marker. pitch dark id rub it in my hands, let the dog smell it then hold the dog back and toss it 100 feet away on the other side of the pool. ( in the dark) he would come back with that rock, or nothing. once it landed in the pool, and he was at the edge of the pool sniffing for it. after he was done looking in the rocks.
one friend was like you should have bet me on that trick lol
