Can Dogs Get Kidney Stones?
Diet and hydration play a big role. A stone that blocks urine flow is an emergency.
Yes, dogs can get kidney and bladder stones, hard mineral deposits that form in the urinary tract. They can cause painful or bloody urination, straining and frequent accidents, and a stone that blocks the flow of urine is a life-threatening emergency. Both diet and prompt treatment play a big role in managing them, and because the signs overlap with a urinary tract infection, your vet will confirm which it is.
Symptoms to Watch For
Frequent, urgent urination can also be a sign of diabetes, so your vet may test for that alongside a stone.
| Sign | What you might notice |
|---|---|
| Straining | Effort and discomfort when urinating |
| Blood in urine | Pink or red urine |
| Frequent small amounts | Going often but passing little |
| Accidents | Loss of house training |
| Pain and licking | Discomfort and extra genital licking |
Treatment and Diet
- See your vet. Imaging and urine tests identify the stone type and location.
- Dissolve or remove. Some stones respond to a special diet, others need removal.
- Adjust the diet. A therapeutic diet can prevent certain stones from returning.
- Keep urine dilute. Encourage plenty of water to lower the risk.
- Recheck regularly. Follow-up visits catch new stones early.
Frequently Asked Questions
What causes kidney and bladder stones in dogs?
Stones form when minerals in the urine build up and crystallize. Contributing factors include the balance of minerals in the diet, urine that is too concentrated, urinary infections, certain breeds, and how acidic or alkaline the urine is. Different stone types have different causes, which affects treatment.
What are the signs of stones in a dog?
Signs overlap with a urinary infection: straining to urinate, blood in the urine, frequent small amounts, accidents, and licking the genitals. Larger stones can cause pain and, if one blocks the flow of urine, a sudden inability to pee, which is an emergency.
How are dog kidney stones treated?
It depends on the stone's type, size and location. Some stones can be dissolved with a special prescription diet, while others need to be removed surgically or with other procedures. Your vet will use imaging and urine tests to plan the best approach, and treat any infection alongside.
Can diet help prevent stones?
Yes, diet is central. Depending on the stone type, your vet may recommend a therapeutic diet that adjusts minerals and urine acidity, along with plenty of water to keep urine dilute. Regular rechecks help catch any new stones early, before they cause problems.
⚠️ Emergency? If your dog may have swallowed something toxic or is seriously unwell, contact your vet or a pet poison helpline immediately (in the US, the Pet Poison Helpline is 855-764-7661).
