breeding and territorial reasons
Well. if your dog is aggressive to some dogs and not to others there are many reasons. First, the dog(s) your dog is aggressive to may be territorial aggressive, meaning that if you live near them then your neighbor's dog may think that the whole street is his territory and your dog is intruding, causing fights and barking. Also it could be something wrong with your dog. There are diseases that can make a dog too territorial aggressive and it can become a big problem. You should talk to your vet if your dog is too aggressive. And one last reason is your dog can have rabies. If your dog doesn't ahve his/her rabies shots then go to your local vet and have your dog vaccinated. I hope I helped with your problem! :D

The hormonal imbalance is not limited to fertility hormones such as estrogen and progesterone, but can also include thyroid hormones. Another reason for a missed period is a tumor that impacts the release of hormones. Most frequently, these tumors are benign (non-cancerous).
