Welcome!!!! You'll love it here, it's chock full a tips,and REALLY nice dog lovers who are so helpul. Im so happy to see that you adopted your Max and your petey. I really don''t know what to say because we have never been in your situation, but with our puppy dog, when ever he barks ,we just take our jar full of pennies, and shake and firmly, with a low, growy, voice, say NO BARK! About the two dogs getting better friends then they are with you, What about taking just taking one dog for a walk, and leave the other...while your on your walk say , with Max, praise him, run with him ,play games ,be fun with him basicly, and then come back take Petey out and do the same. I don't know, it might work
