Boston relative fighting

Question
I have a Mom and Father Boston Terriers and their 9 1/2 month old son.  Father, Chubby,  has started attacking son, Orca, which has been twice w/ a couple little bloody marks.  Today, they were all outside fenced yard potty time & couldn't get to them fast enough & front legs got pretty scratched up treated & called vet & now at vet.  Will Chubby stop this when he is neutered??  Normally such a nice-tempered dog, Orca is a very sweet loving dog & therefore doesn't really fight back, & is young.  Obviously, they will never be unsupervised again, but that seems crazy but necessary, & yet I don't feel I could let either go, but I also won't allow Chubby to get near Orca without us, but any suggestions & why is he wanting to "kill" a very loving harmless puppy? For the record, even though Orca is only 9 mos. he is little taller than dad. Orca is not trying to hump Mother & she is not in heat, & we are getting Chubby fixed before her next heat & Orca, I just can't take this fighting!!! Any suggestions are appreciated.  Thanks

Answer
Terriers will spat my femael boston terrier offen gets pissy with my jack russell male both are altered but she gets mad for him trying to take a toy or treat from her and trys to attack lucky there havent been any scraps yet...but I know how badly he could hurt her if he got angry also. Neutering all may help it may not male terreirs under the same roof are prone to fighting and I persoanly can say I will never have so much as another male dog while I have my jack russell terrier because I know he would just hate another male dog as he isnt even great with female dogs lol....do get them altered asap, and avoid givng them rawhides or large biscuts while tehre in the same room as if one finishes first that dog might try take theothers and a fight break from this....male dogs normaly when not neutered dont get along whatso ever so its very normal.
