Why is my chihuahua puppy peeing on my bed after going outside?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 4 months and 6 days old | 3.968 lbs

My 4 month old chihuahua has been lately coming up to my room getting up on the bed and just pees. She’ll pee outside and 10 minutes later she’ll do it on my bed right in front of me. She still pees in the house as she’s very hard to house train. She won’t pee on the puppy mats in my room, just my bed. My bed and room reeks of pee. Please help me. I want her to sleep with me on my bed but I need her to stop urinating on my bed.

Thanks for using Petco Pet Education Center, formerly Petcoach! Inappropriate urination is often a medical issue and possibilities include a urinary tract infection, urinary tract stones, among other possible medical reasons. Another possibility is that this is behavioral in nature. I recommend that you have Millie evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Good luck and best wishes!
