Weeing

Question
Hi we have a 15 week old terrier she i s quite well puppy trained but sometime shen wees on the sofa even after we just let her out for a wee. we do have a older larger dog.thanks

Answer
Several possibilities here:
1. Dog is not really house-trained yet.
2. If she's a spayed female, she could be spay incontinent (usually pees in her sleep, or tends to dribble).
3. She's anxious and pees on your couch because it smells like you.
4. Other dog is restricting her movements and she has no where else to go. (This can happen just through eye contact - doesn't have to be openly aggressive.)
5. Urinary tract infection - frequent or painful urination, or urine tinged with blood.
First thing I would do is take her to be checked by the vet for possible UTI, and go from there.
