Unfortunately, some Dobermans become very dog selective as they mature from puppy to adult. Others may simply become unpredictable and sometimes aggressive when around other dogs. I have owned both.
If your pug is a female also, you should become aware of the fact that Dobermans as a breed are prone to Same Sex Aggression. Years ago, I had two boys who were best of friends. The were raised together. One day the 5 yo decided that his 7 yo "brother" had to die. His brother didn't see that as viable option and they engaged in a death match. Fortunately (unfortunately for my hand, wrist and arm), I was able to separate them. They lived in a "Crate andRotate" situation for years until the older boy died of natural causes.
I would definitely consider "resource guarding", as greenkouki mentioned, as a possible factor in your girl's actions. Hence, until you have a clearer idea of what is going on I would:
- NEVER leave them alone unsupervised
- Give them each a separate and distinct place to rest and sleep.
- Feed them separately. Ideally in separate rooms. Same with treats.
- Keep them both leashed if they are interacting out of doors.
- Do not allow them to share toys. They should each have their own.
- Try to see how your 3rd dog fits into this relationship. It could be a factor.
- Finally, it is very important to learn how to read your Doberman so that you can, at all times, be aware of yours girls state of mind including her immediate level of comfort.
Generally, Dobermans, with practice, are very easy to read once you learn how.
Oh... Also... Don't try and correct this unwanted behavior by smacking your girl on the nose. It will not work and may, in fact, have the opposite affect.
In any case, best to you and your 3 fur kids!
Edit to say: I have a friend who returned home to find her young mature Doberman female had killed her older and much smaller male. They had always gotten along. It came out of the blue and may not even have been unintentional.
Dobermans are extremely powerful dogs with tremendous biting force. Their medium size belies their strength. What might be a simple admonishment and warning to a bigger dog could easily maim or kill a much smaller one.
