If she has shown signs of dog aggression, I would notbe fostering her in a home with other dogs unless you are VERY experienced with working with dog aggressive dogs. And yes, dogs that are aggressive to adult dogs can also be aggressive to puppies. I have actually known dogs to be aggressive and intolerant of pups but OK with adult dogs. This dog is also a cross of breeds that dog aggression is known in. Plus her age, she is a senior dog. Seniors tend to be less tolerant of things than younger dogs. The other issues is how much warning will she give before reacting? Many dogs sadly learn that their body language is often not repsonded to ny humans and they learn just to go right for the end game – the bite. The same thing can happen when dealing with other dogs. If the other dogs are not up on good doggy language within their own species (basically the humans have socially retarded them to their own kind), other dogs may learn to stop giving warning and just go for ending the annoying behavior. I would not recommend fostering this dog with your pup. Maternal instincts kicking in is sort of a myth. Dogs are generally social and like bonds, but not all of them. Female maternal instinct is more regulated by hormones than seeing a puppy. Heck, many females will not tolerate pups that are not theirs and may stop tolerating even their own puppies once they grow. Hope this helps. But see if another foster home experienced with dog aggressive dogs can foster her.

how do you know if a dog will attack a puppy? the title of the thread and then you asked about a puppy without stating if you had one or not… So safest to assume that you have a pup as well. I know mushers and husky breeders and breeders of other dogs lumped under the term Husky. They were not bred to watch kids… Huskies were bred not as companions but as working dogs. Other dogs in the husky family were bred to also hunt. Now you state Husky trainer… was this person someone training sled dogs? I know people who do and none of them have ever stated these dog were bred to protect kids. As for the pup issue, again, no way to tell except by watching body language when the dog is near a pup and intervening if she seems stressed or is giving signs that she may attack. But if she is showing dog aggression… Big red flag for me. Be aware, in the US, there is NO standard for what someone needs to have to call themselves a trainer or behaviorist. It is also hard to pin down. I have known many people who learned very much the same way I did (life experience and mentors combined with reading. research and taking lectures whenever possible) who I consider far more educated and knowledgable regarding dogs than many I have met who have gone through various programs and even have degrees in behavior. So just because someone is calling themselves something does not mean they are experts. The Siberian Huksy was originally developed as an edurance and speed dog for long distance work. The Siberian temperament has been described as: "While capable of showing strong affection for his family, the Siberian Husky is not usually a one-man dog. He exhibits no fear or suspicion of strangers and is as likely to greet a would be thief as warmly as a trusted family member. This is not the temperament of a watch-dog, although a Siberian Husky may unwittingly act as a deterrent to those ignorant of his true hospitable nature, simply due to his intense personality and appearance. " http://www.ooowoo.com/FAQs/siberian_huskies_FAQ.html#his basically, they are not really protective dogs. "Siberian Huskies have an extremely sociable nature that makes them useless as watch dogs. In fact, if a burglar broke into your home, your Sibe would likely show him where the money is and then invite him to play. A Siberian might do harm in kissing a burglar to death, but that can take some time. http://www.giftking.com/DOGS/siberian_huskies_behavior.htm Much of this info can also be found at the Siberian Husky Club of America site… (www.SHCA.org) They are not often an aggressive dog but dog aggression is not unknown in the breed either. Some are fine with the teams they run with but may not be tolerant of other dogs. If they are not socialized with dogs outside what they live or work with, they may be aggressive to others. But this can happen in any breed or corss of dog. Also defined that they have a strong prey drive. This can mean that they are more likely to give chase and react to a prey situation. Many dogs that have been implcated in fatal attacks and mauling fo humans are breeds known with a strong prey or chase drive. Not that they are dangerous – but that drive to chase moving objects can lead to trouble if not properly managed. Also, the dog is a cross – and one of another breed with a high chase drive and that can be dog aggressive. Border Collies are a tough breed to handle. They are bright, quick to learn, energetic to an extreme. Now BCs are not recommended ofr homes with kids – especially young ones… http://www.swiftdogzbordercollierescue.com/tips.html "The following behaviors can be witnessed in ANY dog, however, Border Collies have been famous for them. A deeper suggestion is be sure the border collie you are interested in has been temperament tested, keeping in mind that this temperament can change once it enters your enviornment. Be sure that the evaluator has plenty of experience in evaluating behavior problems within dogs, more importantly with Border Collies. Behaviors such as: Aggression towards other dogs, food aggression, aggression towards other animals, aggression towards people outside the family, aggression towards people inside the family, aggression towards children, fear aggression, dominance aggression, separation anxiety, and naurotic behaviors such as obsession, pacing, barking, herding, destructiveness, fence jumping, bolting, digging, strong insecurities, thunderstorm phobia, and even mild to severe seizures or convultions have occurred within the Border Collies. " I would just not have the dog in the room with the baby at this point and seriously consider having a good trainer who has taken the time to learn seriously about the history of various breeds and more accurate history to work with you. (I have spent years contacting breeders, dog clubs, rescues, etc to learn about hundreds of breeds since I will not be able to own a good representative of them all! there are over 400 recognized breeds in the world). Seriously, contact both Border Collie and Huksy rescues in your area and ask if any can recommend any trainers. Rescues are often good resources because they do not want the dogs to come back. They want successful placements and are often bluntly honest regarding the dogs and their temperament. Sadly, I have run into many supposedly good trainers who I am shocked how little they know about certain breeds they claim to know. When I run some of my experiences with trainers past rescue and breeders I know, they laugh… Best of luck!
