My 9 year old sheperd/sheltie mix, who has been trained for years to go to the bathroom outside, has suddenly started urinating on the carpet by our front door (although she goes out the back door to do her business). We have a new child in the home (11.5 mos old), the only new variable. This has been going on for about three weeks. Any idea why? Please help, my wife is going crazy!!
This could be a urinary tract infection. I recommend a visit to the vet for a check-up. Antibiotics may clear this up. vetcare
