I'm certainly no expert . . . my boys are 2 yrs apart. It took a little bit, but not too long to get used to each other (week or two till buddies). Woody is now 6 and very much an A personality, Bogie is 4 and very B personality. I would maybe try sitting with all 3 on the floor and try to play
I guess I has it easy, Woody was depressed from the loss of Mika (our golden) and was kinda happy to have a playmate again. Especially one that wouldn't try to boss him around.
