Apatite stones in dogs

Apatite or calcium phosphorous stones are the least common type of stone I see in practice. These rare stones form from the same risk factors responsible for calcium oxalate stones. These include increased amounts of calcium and/or phosphate in the urine. The one big difference is pH. While calcium oxalate stones precipitate out of acidic urine, […]

Removing Urinary Stones With Lithotripsy In Dogs

Lithotripsy is an alternative to surgery for removing urinary stones (uroliths) in dogs. For this procedure, the dog is placed under general anesthesia. Next, an endoscope is passed up the urethra to the stone. Once it is in the correct area, a laser is fed through the scope into contact with the stone. Energy from the […]

Urate Urinary Stones in Dogs

Ammonium urate or urate stones in dogs are common in Dalmations and bulldogs. Dalmations lack the enzyme needed to convert uric acid in the urine to allatoin. As a result, their urine contains high concentrations of uric acid leading to formation of uroliths (stones) in the urinary tract. Urate uroliths are also seen in dogs with […]

Struvite Urinary Stones in Dogs

Struvite is the common name for magnesium ammonium phosphate uroliths (stones) found in dogs. These stones may occur anywhere in the urinary tract including the kidneys, ureters, urinary bladder and urethra. Struvite stones often form when the dog has a urinary tract infection with bacteria that produce urease. This enzyme leads to over production of […]

Hypoadrenocorticism (Addison’s Disease) in Dogs

Hypoadrenocorticism or Addison’s Disease is a serious health problem that can cause death if left untreated. In this disease, the adrenal glands fail to produce two very important hormones, cortisol and aldosterone. Cortisol is the stress hormone important for regulating heart rate and blood pressure. Aldosterone is the hormone that regulates electrolyte levels. Without aldosterone, levels of sodium plummet while potassium surges. Without […]

Weight Loss and Poor Appetite in Elderly Cats

Weight loss and/or poor appetite is a common problem in elderly cats. A cat who used to be a good eater suddenly becomes selective, refusing to eat any food consistently. Concerned owners try all kinds of foods including a variety of canned and dry food, human baby food and home cooking. Unfortunately, the results are disappointing, the cat will […]

Tear Stains in Dogs

Tear stains are a common problem in toy breed dogs due to their confirmation. Once and awhile, a dog with normal confirmation will develop tear stains from a blocked tear duct. In either case, tears spill down the face usually between the inner corner of the eye and nose. I was taught in veterinary college that the stains are […]
