Yesterday, I had a case of a Cavalier King Charles, female, 6 years passing smelly cloudy urine. She yelped occasionally when she peed. So I asked the owner to send me a sample of the urine.
On March 2, 2013, she collected the urine in the clean pee tray and sent it to me. Urine analysis show pH=6.5 which is acidic and calcium oxalate crystals 2+. Bacteria was "occasional" and there was no blood in the urine.
I advised X-rays which showed no stones but I could see radiodense cloudy urine inside the bladder. I palpated the bladder confirming no big stones.
I turned the dog upside down on the examination table and discussed this case with Dr Daniel. I noted that she had unusually enlarged nipples as if the dog had given birth a few times. "She had never given birth," the owner in her late 30s said to me.
White cloudy discharge appeared at the vulval area but the owner did not want to see it. "This could be pyometra," I said to Dr Daniel who disagreed. He thought it was just white turbid urine. The dog could be incontinent but the owner did not complain about incontinence or leaking urine. She said that the dog no longer came into heat although it usually happened around February. I palpated the abdomen. The dog did not experience any abdominal pain but I could few swollen uterine horns of around 2 cm in diameter.
This dog lived in a house with a garden and sometimes the owner might miss the bleeding as the dog cleaned herself well by licking. This would account for her swollen vulval lips.
"So what to do now?" this was what the owner wants to know. She was a busy lady and all those technical information did not interest her.
"Put the dog on U/D diet for 3 months and don't feed any treats or food. Monitor the urine 4 weeks later to check for the presence of calcium oxalate crystals. Monitor amount of water being drunk daily."
As to why the dog "yelped" occasionally when peeing, this was a mystery. This was the complaint. Not difficulty in urination or blood in the urine as in the 2009 case I reproduced for readers below:
