Why is my adopted pug humping, aggressive, and has smelly urine?

Updated On September 23rd, 2025

Pet's info: Dog | Pug | Female | unspayed | 3 years and 8 months old | 25 lbs

I adopted a 3 year old pug from a not so nice circumstance in February, she has had a bit of a hard time adjusting. She had her period around June/July. The photo I have attached is from a few weeks ago when she peed in the house and it smelled really really bad. She never seems to look in pain when urinating. And she goes daily. She has recently been trying to mount and hump me when I bend over and is attacking my childhood dog and vigorously humping her as I dog sit her this week.

Having Porscha spayed may help to curb some of this behavior. Intact females may be more aggressive than spayed females but this is not always true. Spaying also has many health benefits: https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/ Dogs will mount other dogs, humans and objects for many reasons. Here is a helpful link: https://www.petcoach.co/article/mounting-behavior/ Canine aggression is a complex behavior as it can stem from dominance, possessiveness, fear, anxiety, resource guarding or a combination. Unless you are very familiar with reading canine body language and training, it is difficult to know why this is happening. 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. Smelly urine is always abnormal and may indicate an infections. Your best option is to first have Porscha examined by the veterinarian. Have her urine checked for infection and discuss having her spayed. The next step would be to work with a trainer to retrain her to model better behavior. I hope this helps and please feel free to post any additional questions.
