Yes you heard me right and I didn't get them confused...Its my 4 month old Lindsey beating up my 14 month old Bailey

She runs around and chases him just to BITE him and all Bailey does is CRYSSSS he is NEVERR mean back (he is too sweet to be mean) she will try to jump on him and bite whatever she can get his ear, leg, paw, just whatever....so sometimes I got to pick Bailey up just to give him peace of mind and sometimes Bailey just crys and crys and crys until I pick him up......Anyone experienced this?? Oh and you know what Lindsey will do she will lay down like she is not going to do a THING and then will Bailey comes close to her she will ATTACK him and try to bite

Is this normal for her being that she is just a puppy...I hope she grows out of this because its getting to the point where they can be on the floor for about 5 mins then....Bailey is off running all over the house trying to get away from her biteing him...Does anyone have any comments or suggestions about this behavior...Does Lindsey just want to play?? But thats no "PLAY" whenever Bailey squills when she bites him..
