My 7-year-old dachshund keeps peeing inside. What's the cause?

I am sorry to hear about your dog! The first step is to have your vet examine him to be sure there isn't a medical reason for this new issue. There are a multitude of issues that can cause urinary accidents, including urinary tract infection, bladder stones, kidney disease, diabetes, and more. If the vet rules out a medical cause you can discuss if this is an anxiety issue or a loss of potty training. Anxiety is sometimes treated with oral medications. In mild cases a pheremone product like the Adaptil collar or diffuser (available online and at some pet stores or vet offices), thundershirts (also online and at stores), and oral supplements like Composure and Zylkene.

At her age there are several things it can be. Your vet can collect a urine sample to check for a urinary tract infection. They can always draw some blood to check her kidneys and blood sugar and for Cushings disease. All these can cause an increase in drinking and urination which will lead to accidents. If all of that is normal, than she may be getting incontinent and they have medication for that also!

Poor LittleBit! When a dog who was previously house trained suddenly starts having accidents in the home, it is usually a sign of a medical illness such as a UTI or bladder bladder stones. She could also be drinking more due to a medical illness like diabetes or kidney disease, also leading her to have to urinate more. I would take LittleBit into the vet in the morning for a physical exam, routine blood tests, and a urinalysis to diagnose what is causing her to have accidents in the home. Once a cause is diagnosed, the vet can prescribe a treatment.

I would recommend to rule out something like an infection in Presley's bladder before you give up on her. Since she can't talk, you don't know the reasoning behind this behavior. The veterinarian will look at her urine sample to see if there are any abnormalities which may cause this behavior. Go from there. If it does look to be more behavioral, speak with a trainer, read some books about housebreaking difficult dogs. Most dogs can be properly housebroken but not all learn in the same fashion. Definitely rule out your medical causes first. I hope this helps to point you in the right direction. Please feel free to post any further questions.

If this is a recent behavior change for Luna, I would be suspicious of an underlying medical problem causing her to have accidents. Some common possible problems that can cause dogs to urinate in inappropriate places would include a urinary tract infection, bladder stones, chronic kidney disease, diabetes, Cushing's disease, or even a bladder tumor. I would recommend taking her to the vet for an exam as soon as you are able to - he/she can do a urinalysis as well as blood work or x-rays if needed to help determine the problem and get her started on appropriate treatment.

Excessive urinations could be caused by a urinary tract infection, kidney disease, diabetes, etc. You should schedule an appointment with your vet for bloodwork and a urinalysis. It could just be a behavioral issue but she should have a work-up to rule out potential causes.

Poor Mickey! A sudden change in urinary habits most commonly indicates a medical issue rather than a behavioral change. Possible causes of his urinary accidents could be due to bladder issues (urinary tract infection, crystals), prostate enlargement (if he was neutered later in life), endocrine/metabolic conditions (Cushing's disease, diabetes) or organ dysfunction (kidney disease or liver disease). I realize that this is a very broad list of possible issues, so try to determine if Mickey has been drinking more, urinating a larger volume, urinating a normal volume but more frequently, experiencing changes in his appetite or in his overall energy level. All of these different behaviors can help to narrow down possible underlying issues behind his accidents. At this point, I do recommend taking Mickey to his vet for an exam and lab testing (CBC, chemistry, urinalysis to start) to treat the issue at hand. I hope that all goes well!
