Cystitis and urinary tract infections are common problems in our canine companions—but as many cases prove, things aren’t always as simple as they first appear.

Recently, a lovely young Miniature Schnauzer named Willow visited vet Jen at Shepton Vets because she was constantly asking to go outside for a wee. Her owner had noticed she was squatting frequently, sometimes passing only a few drops of urine and at other times producing small puddles. On occasion, the urine even looked slightly pink. Although Willow seemed bright and well in herself, she was a little uncomfortable when her bladder was examined.

Helpfully, her owner had brought in a urine sample, which allowed us to test immediately for signs of infection. The results confirmed a urinary tract infection, and Willow was prescribed a short course of antibiotics. In straightforward, uncomplicated cases – much like in people – symptoms usually resolve within three to five days.

However, when Willow returned for a follow-up appointment, her owner reported no improvement at all. She was still squatting just as frequently. As her symptoms hadn’t responded as expected, we recommended further investigation.

Willow was admitted for additional tests, including blood work, X-rays and an ultrasound scan. These revealed the true cause of her ongoing discomfort: a large bladder stone along with several smaller ones. The stones were irritating her bladder, which explained her persistent urge to urinate.

In some cases, certain types of bladder stones can be dissolved over six to eight weeks using a prescription diet alongside antibiotics. In Willow’s situation, however, surgical removal was the safest option – particularly as some of the smaller stones posed a risk of causing a urinary obstruction.

A few days later, Willow returned to the practice for surgery, carried out by vet Sarah. As you can see from the image, she had developed quite an impressive collection of stones for such a small dog, the largest measuring 2cm in diameter. The stones have been sent for laboratory analysis to determine their composition. Depending on the results, Willow may be placed on a special prescription diet to help reduce the risk of recurrence.

Throughout the whole process, Willow behaved beautifully and has made an excellent recovery.

If you notice any changes in your pet’s urinary habits – such as increased frequency, straining, discomfort, or blood in the urine – it’s always worth having them checked. Bringing along a fresh urine sample can be incredibly helpful, providing valuable information that supports accurate diagnosis and effective treatment.
