It depends. After you recive the dog you should be socalizing it with TONS of people/dogs/sounds/places. However, if you have done your part in socalizing then yes, the responsiblity falls to the breeder. If your dog is having temperment problems and you have done everything you can it is probably bad breeding.
It all depends, each puppy in a litter will differ in their temperment. Submissive up to pushy. But if things like the mother is timid(Which can effect the puppies), or the puppies have not been at least partially socialized to people and life in general, The mother is hyper active, all these things can have an impact on the puppies temperments, this they should be liable for. But the general public does not know enough about it to make those connections.
When I look up into the sky, I think to myself, Wheres the ceiling?
If the puppy is scared of it's own shadow, terrified and shaking when you attempt to touch her, won't eat or drink ,and runs and hides any time someone enters the room, yes, the breeder is responsible. That's a scenario for a young puppy. In our breed there is a term used for certain dogs that attack other dogs, (usually males) called rage syndrome. I think it's a pile of bull, and is the fault of the breeder. I also think to breed, or continue to breed that dog is a mistake. There are leading breeders of Bostons who disagree.
Quite frankly, I need alittle bit more info to make a decision. As I see it, if you just got this pup, and having problems with it being timid, shaking, scard of you etc. depending on the breed, yes that is a problem.
If you have had the pup for some time, did everything you could to socialize it, take it to obediance, and take it everywhere you possible could, then yes it could be a problem
Different factors in a pups life can mean different things. If they are around loud children, they can get scard. People fighting can be a problem, etc. I know our breed can go through a fear period, no matter what you do. You just work them through it, and they do great. If you try to hide them from things, it can turn into a very big problem later.
There are certain bloodlines in Bullmastiffs that have proven to be very unstable, to the extent that within two years of a litter being whelped almost every one of the pups was put down for people agression even turning on the owners. Because I have been in this breed for so many years I am aware of this problem and refuse to breed any of my dogs to one from this background. I have seen bad temperament seem to disappear for a generation and come back with a vengance.Good temperament is important in all breeds but it can be a matter of life or death when dealing with a large or giant breed.I have made enemies in the past for refusing to use my stud on females that were champion titled and had won many best in shows. I don't care how great a dog does in the show ring if the temperament is off then it shouldn't be used for breeding.
To an extent, yes... but the problem with that concept is that it's 50/50 genetics and enviroment. If it hasn't been socialized, trained, properly cared for... those are all BIG factors as well. A breeder can't make a great dog... they CAN ruin one quite easily... but since the owner chooses the breeder, the puppy, and is responsible for all care after it leaves the breeder - I think it can be argued that the attitude of an adult dog is more the owner's responsibility.
Drogheda Bullmastiff on this one I totally agree. I will not breed to those lines that show this kind of aggression. I don't care how many titles a dog has. No matter how nice a show dog is, what the heck are you suppose to do with them after there show career is over if they are dangerous. Not to mention the whole personal responsibility issue.
Having a kennel full of dogs is hard enough without having to deal with over aggression issues. But to make that kind of call, you have to know the whole story. I mean after a pup leaves your care, and if they were to take it home and beat it like a red headed step child, how can someone as a breeder gaurantee that.
He's your friend,your partner,your defender your dog.You are his life,his love,his leader. He will be yours faithful and true to the last beat of his heart.You owe it to him to worthy of such devotion
A few years ago I received a call from a woman I met at puppy obedience class. She was in tears and begged me to take her female Bullmastiff pup,Cabella. She said the dog had attacked her son and her husband wanted to shoot the dog. I could not imagine such behavior from this dog as I had spent plenty of time with the dog and its owner and had shown the owner how to trim the pups nails. She brought Cabella to me and after she left I noticed the pup could barely walk and wasn't putting weight on her back legs. A trip to the vet resulted in a diagnosis of torn cruciates. I contacted the owner and finally was given the real story of the attack. Seems the woman's two sons were tormenting the dog by pulling her by her back legs while she was eating. She finally growled and snaped at one of the boys and made a tiny cut in his ear lobe. After surgery she was placed for adoption and now has a wonderful home with people who love her and children who know how to treat a dog with kindness. I have taken in many abused Bullmastiffs over the years and very few have actually held a grudge against all people because of the pain they suffered at the hands of an abusive owner, most were able to be adopted and have been excellant companions in a new family. Truely good stable temperament will survive a tremendous amount of abuse .
I read the story of the poor pup that needed surgery. How could parents just sit there and allow that to happen. Unbelievable. Dogs are amazing in that they will not hold grudges and can move forward, so full of love and grace.
IMO it depends on things such as: how long have you had the pup in your possession? What age did you get the pup? What excat behavior is he doing that you are calling 'aggression'? What kind of classes, socialization have you done with him?
The only dogs I can vouch for 100% are the ones I bred and have raised from birth... Poorly socialized, badly handled, badly trained dogs can have awful attitudes - that doesn't mean they are genetically badly bred. If you're seeing multiple dogs from the same line and/or litter exhibiting the same issues and all were raised in different environments... then I'd be suspicous of it being an inherited issue...
