Aggressive Boston Terrier

by Tamm;y

My Boston is very protective my husband and me. She does not like other dogs either. How can I get her to be less aggressive to people? Everyone says "oh" what a cute dog and go to pet her and the hair stands up on her back and she starts to grumble as I call it. We have had her since she was a puppy and is now 4 years old. Is this normal in Boston Terriers?

Rescued Boston is aggressive when I am around
by: Anonymous

I rescued a 2 year old Boston two years ago. In that time, he and I bonded pretty well. Recently my mother had to put down her Golden Retriever of 14 years. She was so heart broken. Because of work, I decided to give my dog to my mom. She at first resisted, because she isn't a small dog lover. But in a week, she was taken by the Boston personality and fell in love. Here is the problem.

Whenever I visit, Charlie, immediately comes to me, and gets over protective. He gets to the point that he even will nip my mom in the hand, when she tries to put his collar on etc....The other day, while in a room, with the door closed, Charlie camped just outside. When my mother approached Charlie to scratch his neck, he turned and bit her.

My mom takes great care of any animal she has. All her dogs have lived long lives, in clean conditions, with the best of care. She takes Charlie on walks, and he is really quite a good dog, until I come to visit.

Why is this dog so attached, my mother says, he is a great dog most of the time, but wow, when I visit, he gets really aggressive.

8 year old
by: Arly

I too have the aggression problem with my 8 yr old female. I have had her since 6 wks, and she has always been a little sweetheart. Not now...she has bitten 3 neighbors...only breaking skin on one, but enough is enough. I have been considering medication to calm her, but I hate the thoughts of "drugging" her. She is great around family, our other dog & family dogs, but just dares a stranger to come into our house. I am at my wits end. Any suggestions anyone?

Aggressive male boston
by: Cory

I have an 8 month old BT that has out of no where become aggressive towards other dogs at the dog park. I've had him since he was 10 weeks old. I have another small dog in the house that is 1 yr. 2 months and they get along great. About 3 months ago the BT latched onto a pitbull at the dog park. The pitbull was not being aggressive at all. When i say latched on i mean he had a mouth full of the other dogs skin and would not let go even after the other dog owner and myself intervened. The next day i got him fixed and waited 1 month to take him back to the park. He seemed to be more relaxed and playful until today, when he attacked a 3 month old akita puppy who was about his same size. He did the same thing as the first incident and would not release the other dog as he cried for help. I'm now looking into behavior classes. I have read how they do not work, now I have no idea what to do. Someone please help.

Fearful Boston
by: Lisa

I am sort of relieved to read that I am not alone. Our 2 year old Boston Terrier, Stewie is fearful of all strangers and other dogs too. He has been very timid since we got him at 8 months but it progressed into fear aggression where he tries to bite. We have taken him to a behavior clinic at University of Pennsylvania and he is now on Prozac with no real improvement and we have attempted behavior modification with minimal improvement as well. It is so frustrating. We just want everyone to love him as much as we do since he can be such a sweet boy. It is also very difficult to leave him in someone's care when we go away since there are only 7 people that he is comfortable with. Anyone have any other suggestion? Thanks

2 year old aggressive boston!!
by: Anonymous

I completely relate to every word you are saying... Betty is nearly 2 years old and she does all of the things you say your dog does. She is so loving towards all the people she knows well but is a nightmare around strangers. It's really stressful because she just will not relax around people she doesn't know, she just barks at them and then runs away when you try and pick her up. She is really nervous, I just feel like she is being protective of us. I don't feel like there is anything we can do to stop her being like this. Postman and any passers by will mean she will stand on the sofa, look out of the window and bark like mad. It's a nightmare but we love her to bits.

2 year old aggressive boston
by: Anonymous

we are having the same issue...we got out female boston terrier when she was 8 weeks old and we did our best to socialize her... at about 8 months old she started becoming people aggressive.. She loves other dogs and immediate family but HATES strangers !! we have to leash her before anyone new comes to our home. Having her off leash at the park is NEVER an option because she has gone after kids and adults that walk by on the rare chance we have trusted her :S She runs in circles barking with a incredibly high pitch bark and wont allow us to catch her ... it is very scary and we are running out of ideas... I have spent soo much money on private training that has done nothing :( at home she is the best dog to our kids and family its incredible what a monster she turns into when approached by a stranger.

Aggresive female BT
by: Stacey

My dog is just over a year old and she is fixed, but she is still very territorial of anyone who walks by our house, especially children. when the mail man comes by (we have a few)she barks, but is really aggressive with only one of them. She is very sweet but does have an attitude just like any adolescent girl :)

why is this happening???
by: Jettacole

wow I toatally thought I was alone on this. My three year old female goes crazy when someone walks by, or she hears a noise outside and God help the person that comes to the door. She has never been aggressive towards my husband, children or myself, but she will go after children that come to the door to play with my kids. I'm deathly afraid she will bite someone. I am so scared we love this animal like she was a family member. My husband works nights so I like the fact that she is protective but seriously I am unable to take her for a walk, or put her outside at all.

I am so afraid that she will hurt someone or herself trying to get at someone that I am sacrifices money to invest in puppy pads for her to potty on, or I have to take her out in the middle of the night when no one is around. She's not a bad dog and she would be a great dog if I could get this and her chewing of clothes and shoes to stop. any ideas on any of these would be greatly appreciated!

aggressive boston to men
by: Anonymous

Just got back from a walk with my boston terriers. My 2 yr old male has become leary of men he doesn't know and if they approach and put their hand out he will snap at them. Does'nt do this to women or children but has now done it a few times to men. (once to a cement guy who approached him with a trough in his hand and twice when workers came into the home carrying equipment and now this guy walking his old dog approaches and snap) He is an awesome dog in every other way but this--Help!!! what can I do? We also have a 1 year old little girl boston. Any suggestions would be greatly appreciated.
P.s. It is important to note that he is in a loving environment with children and my husband who is very loving to him, so I can't quite figure why he doesn't like men.

Aggressive dog

I have the same problem with my male BT. I've had him since a puppy and he is now 4 years old. I recently had him neutered hoping it would help with the problem but hasn't so far. He is very leary of strangers and begins to growl at them when they come near him. If they attempt to pet him, he snaps at them. He even does this to children. I am afraid he will bite someone.

same problem
by: Nicole

i have the same problem with my male boston. i thought it was because he is not yet fixed but he has a very strong fear of strangers and does the grumble as you call it and back away. i'm curious because yours is a female if this is not due to testosterone. if you find any info, let me know.
