I have trained pups and dogs and while not an expert, I have had success, but now for the first time I will be introducing a new pup to the household and her new "brother" who is 5.5 years of age. My question concerns conducting the basic training with the new pup ie. should I include Kenji in the training or in have him in another room. My initial thought was to do it separately with Kenji in another room, but my concern is having him feel left out which is the last thing I want to do to come to resent the puppy. Appreciate any thoughts and experiences others here have had. thanks.
