My dog's first heat: Is aggression & sensitivity normal? Can I bathe?

That’s hard to say. Certainly her hormones can make her more unpredictable and prone to mood swings. If only she could talk and tell you! There could also be an element of her maturing into an adult dog now and this will sometimes change things in her idea of the human pack structure. Because of situations like this, I recommend to spay or neuter all pets who are not intended to be breeding animals. It tends to keep them more even keel and generally exhibit less signs of aggression or dominance. I hope this is helpful and please feel free to post any additional questions.

Spaying both dogs is going to help, as it will take hormonal cues out of the equation. You may need further socialization and dog-dog aggression help as well. Please consult this fantastic dog behavior website for more information and free tips: www.dogstardaily.com.

No, stress should not alter her normal heat cycle. Older non neutered females are very prone to womb infections which can be severe and life threatening. Any changes in timing, volume or color is a concern and full health check would be recommended as soon as possible, urgently if any fever, vomiting or weakness is present

I would be suspicious there is another cause for the change in behavior. Swelling of the vulva happens early on in the heat cycle but everybody is different. With her age it’s possible she may not proceed quite as normal since she is young. It’s possible she does not feel well. It’s also possible she is starting to test her boundaries and where she fits in the pack hierarchy. Since she can’t talk and tell you, I recommend to have her examined by the veterinarian. If the veterinarian does not find any obvious source of pain, they may look into a bladder infection or anal gland infection as a cause for discomfort. It is always important to rule out medical causes. I hope this helps.

Thanks for sharing your toe, however since we aren't human doctors there isn't much that can be done for that and you should visit your regular doctor. That said, if this is linked to your dog being in heat, keeping the two separated during her heat cycle may help reduce the behavior and prevent a fight from breaking out. Having your female spayed may also help reduce the aggressive behavior if it is related to her heat cycle as she will no longer have them. If the behavior continues to escalate, keeping the two dogs apart and speaking with a trainer in person is best so that they can address the issue and provide a more tailored plan. Picking up and keeping any and all toys, etc removed during this as well as feeding the dogs separately may also help reduce the behavior as well.

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.

This would be very uncommon 2 weeks after heat but could be related a false pregnancy (generally seen around the time a dog would be due to give birth). Hormonal treatments may help to reduce the symptoms - contact you rvet for a full assessment
