Oh dear I'm going to attempt to tag some others for u keep ur fingers crossed it works lol @JAKEISGREAT @savemejeebus @cowsmom @desertskybulldogs!!! Ok now ill give u my advice I went through the same thing with my girl!!!!! I have so many scares from her deciding I was a toy, she would get this look n I swear actually attack me it got so bad that I actually broke down crying n telling my fiancé that our dog was evil and she hated me lol!!!! Now she is my little snuggle bug n wants nothing more than to curl up on my chest n sleep (she's 9 months old but has been thins way since about 5 months) I think it's just a stage however ill give u some advice given to me at that time!! Only play on the floor n when the aggression starts a stern "no" or "leave it" n the play time is done u need to remove urself from the situation, go to another room or sit on a couch n play time cannot resume until he calms down!!!! N again if u resume play n their is aggression, no n remove urself!!!! I used bitter apple spray on my hands as well (I are more than she did yuck lol) but it seemed to work well!!!! It's all in being the dominate n if u say "ok ur being mean we r not playing anymore" u r assuming the dominate role!!!! He is a baby still n views u as his litter mate so u need to teach him u r not!!! Praise when he chews his toys is great so keep doing that !!!! Try getting some very hard rubber toys as well I suspect he is probably cutting teeth too (my vet showed me porky was lol she got so bad I took her to the vet lol) good luck n keep is updated!!!!!
