Why is my unneutered dog growling when waking up? How to stop it?

Neutering will decrease testosterone levels which can in turn decrease chances of aggression, so any dog that is intact and is having aggression issues, neutering is recommended. That being said, sometimes the behavior becomes more of a habit and because of this, neutering isn't a 100% guarantee to fix the issue, but it is at least the first step.

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. Certainly male dogs who are not neutered are more prone to fighting and aggression. Neutering him may help but it will not likely solve all the problems. Best of luck.

Neutering will definitely help, but it won't be an "off switch" for his dominance. A pheromone product, such as the Adaptil collar, may help the behavior. Consider formal training/obedience classes. Make Billy "work" for everything. If he wants to go out, play, eat he has to perform a task (sit, stay, etc). Correct negative behavior immediately. Praise and reward him when he complies. Ant treat or reward he gets should be tiny. If he acts up or gets too wild, place him in a different room or area (not his crate) until he settles down. Be firm and be consistent.

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.

Intact males tend to be more aggressive but again, aggression is complex and it may not solve the problem. Best of luck.

Neutering can sometimes help with interdog aggression, so if you plan on keeping them both, having them neutered may help. If they are constantly fighting with each other, it may also be time to bring in a professional who can view the situation in person and help formulate a training plan to get the dogs OK around each other. You may need to keep them completely separated and slowly introduce them in a neutral location such as on a walk, and then only have short monitored sessions until they can be trusted around each other. However, if one dog is lunging and growling before even being introduced, seeking professional help is best.

First, neutering Freckles can help. I do recommend having that done. Then I would put him in with a professional behavioral expert for training. I never recommend owners work on aggressive issues by themselves due to safety issues. Your vet can make a referral to one for you. Best of luck.

Now is the best time to neuter them both. Neutered males are more docile and make better pets. When they reach sexual maturity at around 6 months and their hormones go into full swing so to speak, they may act aggressive toward other males and want to become dominant in the household. If you wait too long, neutering will not help. I suggest neutering all dog sin the house as soon as possible, then the hormones will die down in a few weeks. At this time, implement a training program with a trainer or by doing some research. The behavior will most likely get better, but that is not definite. Neutering with combined training is your best plan to change his behavior. .
