My two male dogs are fighting. What can I do to stop their aggression?
Updated On September 23rd, 2025
Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 3 years and 1 month old | 50 lbs
My two male dawgs won't stop fighting. Usually me and my brother grab one each and when the terrier lets go of the lab cross, we seperate them. Usually reintroduce them and they're fine until next time it happens. However this time the jack Russell will growl and lunge as soon as the other walks in the room. We kept them both on a lead after walking them. Nothing's working, neither are neutered will this stop it happening? They're 3 and 15 months.

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.

Try to determine what is setting them off. Once that is accomplished, you can remove or reduce the negative stimuli. Provide extra food/water bowls, toys and bedding to prevent aggression from resource protection. Feed them separately to avoid food aggression. Pheromone products such as the Adaptil collar or DAP plug in diffuser may decrease anxiety or aggression in the home. Consider a consultation with one of our experts, Dr. Jennifer Summerfield. In addition to being a trainer, she has experience in dealing with pets with behavioral issues.

You must first establish what they are fighting over. Is it food, toys, attention, territory? You can start by minimizing the problem. If it is food, feed then separately and take up bowls once finished. You may have to go without toys if they can't get along. Make sure they are both neutered as this can also help. You may need to consult a trainer to resolve any other issues or possibly rehoming one if it can't work for their safety

It's possible, and if there is, having both of your dogs neutered may reduce the fighting. Other possible causes can include pain or illness, as those can both cause sudden behavioral changes in dogs that may cause them to lash out. I would separate both dogs, and have a vet checkup to rule out any health issues. if they check out healthy, having them neutered may help. If you don't wish to neuter them, it may be a good idea to speak with a trainer or behaviorist in person who can observe their behavior and help formulate a more tailored plan. Slow, careful introductions may help, and if the dogs become too nervous or excited, separating them until they are calm again is best before reintroducing.
