Why is my previously potty-trained dog suddenly peeing on the sofa?

Pet's info: Dog | Toy Poodle | Female | spayed | 1 year and 10 months old | 9 lbs

My dog has been potty-trained since she was 3 months old, but she's suddenly peeing on my sofa. I washed everything (including the sheet n cushions) , and the moment I put them back, she couldn't wait to pee on it again. What may be going on? Thanks!

She may have a urinary infection that causes her to have accidents due to not being able to hold it as Kong. She may be doing this out of stress or anxiety or something has changed in her environment or routine. Depending on where she is in her heat cycle it may be due to marking and territorial problems influenced by hormones The best place to start is gave your vet check for infection with the urine then look in to getting her fixed. From there you can look into repeating house training or behavioral medicines

    In such a young puppy this is likely a behavioural issue, you need to persistent in house training as accidents are really common at this age. Be firm but try not to chastise her. You could have her urine tested to make sure she doesn't have a uti but I think this sounds behavioural not medical.
