Why are my fixed male dogs still fighting, living near a puppy mill?

Neutering both dogs at 1 year of age may help if this is related to the female (male dogs may still try to claim possession of her even if she is fixed). If the younger dog is already exhibiting undesirable behaviors, you may look at neutering him now. There is a possibility this is not related to the female. Working with a professional trainer may be your best option. Also, after the neutering, the hormones will still be around for about a month so it’s not instantaneous. I hope this helps.

All you can do is keep them separated - best to take one of them to another location (a family or fiend's house). I suggest you have them spayed/neutered (or at least one of them) or this will be an ongoing problem.

It's best to have a vet evaluate your dog's injuries after flushing any wounds thoroughly with normal water. To prevent this fighting, you have two options: 1) Keep the dogs seperated 2) Get the dog spayed/neutered Otherwise the fighting will continue and there's really not much else you can do about it. I hope that helps and everything is OK.

At this stage you are not likely to correct this behavior. It is not uncommon for two female dogs that are not spayed to fight. You can have one or both of them spayed - that might help but there is no guarantee. The best thing to do is keep them separated at all times. If they have to be in the same room together then I suggest you keep basket muzzles on them so they can't hurt each other.

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.

Unfortunately male dogs can smell females in heat up to two miles away and they will try to break in. It is the responsibility of the owner of the male dog to keep him under control. I would call the police telling them that this stray dog is damaging your house and trying to get in and you need it moved as you are also afraid that it may attack you. I am not sure if they will do this, however since property damage is involved, they just might take the case.

This is normal. If you don't want them to breed, you need to keep them separated. You may have to move one of the dogs to a friend or family member's house until the female is out of heat. I suggest you have them fixed as soon as possible. ( http://www.vospca.org/affordable-spay-neuter )
