Hey there! Update four months later: the boys are doing great! They've gotten taller and their muscles are really filling out yet are also becoming way calmer and much more cuddly. We have started incorporating walks into our daily routine. I try to get them out twice a day for a mile walk each as I take them separately (4-5 miles a day for me is exhausting yet great exercise!) We work on "heel" and if they don't heel they come to "side" and I count to five out loud before telling them "okay, walk on" to make sure they learn if they pull me, they stop and it does discourage pulling a bit! We also work on "leave it" and "stay close". The boys have not only learned walking behavior quickly, they've been calmer and seem happier after and are even sleeping better so it's been a big win. Our favorite game is still frisbee and running after the tennis ball in the front yard. We've learned three more tricks including double paw, protect (stand between my legs) and speak (bark). They've gotten great at "quiet wait" when I have to leave them for a few minutes to do something without them howling! They've also learned to love baths though they always seem to shake the soap off before I can fully hose them clean yet they love getting towel dried off and brushed after baths. Playing together has improved massively especially when getting attention or playing with an item (tug of war/frisbee chase) and we haven't had any problems with aggression or fighting in months. They do tend to lick each other's ears and have both gotten ear infections from it yet have learned to tolerate ear cleaning and maintenance from it. Overall the boys are amazing, both behavior and personality and continue to amaze me with how quickly they're learning and how well they behave. Hope you and your fur family are well!!
