We have a 9 month cane Corso and she just had her first heat cycle. We also just got yesterday a 10 week old male cane Corso. Our female gets real aggressive sometimes with him…this normal or cause of her hormones or not socialized enough? She has been to training and obedience classes and did well. We was just curious cause we plan on breeding them in about a year
I would suggest that before you consider breeding, you get involved with a cane corso rescue group and see just how many of these dogs end up in bad situations because of unknowledgable breeders, etc. https://mustlovecorsosrescue.org/ Cane corsos can easily have dog aggression issues. You can't just bring home a new puppy and expect the existing cane corso to accept the new dog. It takes a lot of time and careful managing to build a multi-dog home. That you do not have a lot of experience to understand why your female is being aggressive towards the new puppy sends up a huge red flag that you do not have the breed knowledge to be a breeder. Please stop and back away from breeding. Learn more about the breed. Get involved with rescue work - they ALWAYS need fosters. And then, after you have gained enough knowledge, you can decide if breeding them is something you want to get involved in. And then you can work with other reputable breeders who can help you navigate.
Is this UK or US? The Cane Corso is not a registered breed in the UK. Although not a banned breed, these lrge molosser types are not the easiest to place in suitable homes. Not fair I know, but you could end up with 12 puppies that you struggle to find knowledgeable homes for. This needs a good deal of thought as large breed puppies can turn out to be a big financial commitment. I'm afraid that I am not aware of the situation in the US. To revert to the problem of the two Corsos that you own, a female that has lived as an only dog will not always welcome the attention of a boisterous sharp-toothed puppy. You will need to supervise the time that they spend together, and allow your female time to relax away from unwanted attention. When the puppy's vaccs are complete they are likely to form a bond by being walked together, but mouthy play is likely to cause a problem for as long as your puppy has needle teeth - which can possibly be up to six months of age.
Our 9 month one hasn’t been an only dog. We also got a Maltese and she gets along with her. She just growls and at the 10 week old Cane Corso and snips at him when he comes around us. Now if I’m holding both the older is fine. My oldest isn’t aggressive at all towards anyone or other dogs.
It's likely that there is also an element of jealousy in her behaviour, as she may not welcome sharing her home and her human attention with an intruder. Very few adult dogs will welcome the attention of an energetic puppy with alligator teeth. It is going to take time before a calm relationship builds between them.
Cane corsos are protectors. Just because she is fine with your maltese doesn't mean she will be fine with a new puppy. Just because she is OK around other dogs when out for walks, etc, doesn't mean she will be fine with another dog in the home. You need to limit how much the puppy is around her and introduce them slowly and carefully. You need to give her a LOT of one on one attention - cane corsos need to be with their people so the more time you are spending giving the puppy attention can be damaging to your bond with her. You need to tread a fine line there.
