Hi! I am new to BoxerWorld. I wish I would have known about the site sooner. There is so much great information. Anyway, we had 3 dogs; 2 boxers (12 and 3 yrs old) and 1 mini dachshund (3 yrs.). As of last night, though, we have 4 dogs. We got our newly adopted 13 month old boxer. Problem is his name is the same as my 3yr old boxer. Any advice on either changing the new pups name or disciplining them without the other thinking he is in trouble. HELP!!
