My friendly dog suddenly growls at family. What's causing this?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | unneutered | 1 year and 9 months old | 154 lbs

My dog is a moscow watchdog who's a bit known for its aggression. The thing is that we have him since he was 2 months old and he grew with us (a family with 6 children, 5 boys and me, a girl) he was friendly and not growling to anyone but in these last weeks he started to growl to one of my brothers, then to mom and now to dad, whenever they are petting him or scolding. Idk why is happening. I rly love the dog and he never did that to me. Dad said he's gonna get rid of him if he ever bites us :(

I hate to hear this is happening and unfortunately, it's impossible to know the real cause of the behavior without being able to observe it. Canine aggression is a complex behavior as it can stem from dominance, possessiveness, fear, anxiety, resource guarding or a combination. Most people are not familiar with reading canine body language and training. Because of this, I recommend to work with a professional trainer. Researching on your own will also be helpful. Familiarizing yourself with canine body language and dog training can help you to recognize what your pet is trying to say. You can find many books written on the topic and there is a trainer named Victoria Stilwell who I think is particularly helpful. I also recommend to have Cezar neutered. Intact males tend to be more aggressive but again, aggression is complex and it may not solve the problem. Best of luck.
