IMO, teaching a dog to heel and stay are the two most important commands/responses for 99% of dog owners. I can call all 3 of mine to heel in any situation and 2 of the 3 are rock steady on sit/stay. It separates them from the pack, pun intended. Get any pup to master those and the rest is icing on the cake (unless they're working dogs of course).
Great looking pup brother. Glad you didn't waste time and hopped back on the band wagon. I've not been without a dog since the 90s and I'm not sure I'd know what to do if I were without. I hope to meet him some day!
