Customer Question

I have a 12 year old female Basenji. I got her as a puppy and like most Basenji’s she had tendencies of aggression towards other dogs, but it was mild: when she ate or there was human food around and sometimes when she did not want other dogs near her.
As she is aging she seems to be getting more aggressive to the point of attacking a brand new dog that I am fostering. Is this because the foster dog is now in her territory and will she continue to attack him? He defends himself even though he is only 15 lbs and she is 25 lbs. Do you have suggestions on how I can get them to get along and not fight. So far neither have been hurt, but I am afraid it is just a matter of time before one or almost a dozen times. My sister has suggested getting her meds, but I really do not want to do this.
I also have another Beagle that she gets along with, but does sometimes growls at him he tries to enter a room she is in.
I would appreciate any advice, thoughts or suggestions.

My name is***** doctor this question was originally intended for does not seem to be available at this time. It is a common problem to see aggression escalate as pets age. As your suggested, my suspicion is that the aggression toward to newer dog is related to the new dog entering the basenji's territory. Although correct any aggression she shows verbally is necessary, I also recommend very slow introduction of new animals. Also, sometimes with some pets, fostering a new animal does not work because they just do not accept someone new in their home.

If most situations, if the new introduction needs to happen, I first allow only scent contact. This involves physical separation of the pet with both having an article of clothing or blanket available that smells like the other pets. If aggression or tension is displayed toward the inanimate object, visual introduction of the new pet cannot begin. If there is no abnormal behaviors toward this object, then I allow sight only contact. The best is to do this OUTSIDE the home. Say at a dog park or walking on the street. Two separate individuals should walk the dogs so they can see each other but not have contact. Once again, if tension or aggression occurs, no physical contact can be made. If no aggression, then physical contact can begin but very slowly and only in controlled manners. Once again, I recommend starting this outside of the home.
