Summer Dog Training

Oh, we are such first time dog owners.  We spent all this time training Oreo when all we needed to do is wait for summer's heat.  He's a whole different dog now that the temperatures are rising.  He hardly pulls on his leash.  At the start of a walk he might make some moves like he's going to chase a squirrel, but by the end of a walk he doesn't even look at the birds or squirrels.
He gets home, drinks all his water and plops on the floor in a cool place. He stays there for a long time, panting as if he's on a full-speed run.  When he does move, it's slowly.
As my husband pointed out, "He's a Siberian Husky, not a Florida Husky."
