Why are my two female dogs fighting? How can I make them stop?

If they are not spayed then you should start with that. Hormones can certainly cause aggression. After the surgery it takes about 30 days for the hormone levels to decrease to a level that may change aggressive behavior. If that does not help then you should consult with a professional in-home dog trainer to help you sort out the root of the problem. I see you are in Puerto Rico. There is a HUGE free spay/neuter campaign coming there in November. I suggest you check it out if you want to get your dogs spayed. Search "Spayathon for Puerto Rico" on Facebook to find their page. Hope this helps. Best wishes.

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.

Hormonal changes that occur after being spayed or neutered can sometimes cause tensions. Keeping the dogs separated unless supervised may help reduce fights. If you notice one or both dogs becoming too excited or agitated, separating them and giving them a chance to cool off can help. Removing items of contention such as treats or toys can also help reduce fighting. If the fighting continues, or they are unable to be together at all, seeking out a local veterinary behaviorist or trainer in person that can observe their behavior may be useful for formulating a training plan to help both dogs get along again.

From this little bit of information it's really difficult to know why the dogs are continuously fighting. Aggression between dogs can be due to fighting over resources such as food toys or attention, can be territorial or sometimes even affected by hormones. Spaying and neutering and helps in many situations if they are not already fixed. Here are some websites with behavior articles that may help. http://www.veterinarypartner.com/Content.plx?P=SRC&S=1&SourceID=47 https://drsophiayin.com/. Good luck

If this is real aggression, you may need to separate them until after the heat cycle and hope for the best. Sometimes problems can persist beyond that. Typically, households with altered dogs will have a lot less conflict than households with intact dogs. There are many benefits to spaying and neutering and I recommend to discuss this with your veterinarian: https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/ 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. 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.

Hi and thank you for using Petco Pet Education Center, formerly Petcoach! I am so sorry that your two pups have not been getting along recently. I would separate both dogs while you are away until you can figure out the issue. A lot of times housemates will fight due to phobias (thunderstorms, loud noises), separation anxiety or aggression. Also, sometimes one dog may have a medical issue presenting it self to be weaker than the other dog. I would make sure both pets are pain free and have no concerning issues like vomiting, diarrhea, weakness, pain etc. A lot of the time, the newer dog in the household tends to be the aggressor. I would work with each dog separately and together for obedience training. If possible, i would get a professional dog trainer to help. A lot of the time it is the people that need training on how to properly time commands for their pups. Once they have a solid foundation of obedience training I would try a few things that will test ability to ignore one another in the same room, then give one dog attention while the other one ignores it etc. I would reward the dogs for remaining calm. This will help teach them that they can be in the same space and tolerate each other. These can be some helpful training tools that you can start with. However, if the fighting escalates, getting a professional trainer would be highly recommended sooner rather than later!
