This dog has….

The dog in the last post has…BLADDER STONES!  Were you able to spot them?


Whats wrong with this dog answer

The two main types of urinary stones we see in dogs and cats are struvite and calcium oxalate.  They appear the same on radiographs so a urinalysis is then needed to try and determine the type of stones present.  The urinalysis may reveal struvite or calcium oxalate crystals (crystals are the building block for stones), a high or low pH (struvites occur with high/alkaline urine pH and calcium oxalate with low/acidic urine pH), and a urinary tract infection (struvites most commonly form when a UTI is present).  If the stones are struvite they can be dissolved with a special diet but if they are calcium oxalate (as was the case for this dog) – surgical removal is required. Unfortunately, the stones can also be a mix of struvite and calcium oxalate so you can get them smaller with the special diet but not fully dissolved, so surgery is still ultimately required.  It is important to address stones right away as they are often painful, can lead to a UTI, can be in the kidneys as well (which can lead to kidney failure if they block the duct leading from the kidney to the bladder), and in some instances (particularly in males) can lead to a urinary blockage where the pet is no longer able to urinate.  In this dog’s case, the stones were surgically removed and then he was placed on a special diet to keep the stones from reforming.

Did you know what was wrong with this dog?  Have you ever had a pet with urinary stones?
