Urinary crystals that require close attention
Calcium oxalate in dogs refers to urinary crystals that form in the bladder or kidneys.

Calcium oxalate in dogs often develops in acidic urine or when there is excess calcium in the bloodstream. These crystals can cause urinary tract infections, discomfort, and in some cases, dangerous blockages.
What causes calcium oxalate crystals?
- Acidic urine (low pH)
- Hypercalcemia (too much calcium in the blood)
- Poor hydration
- Improper diet
Tips to help prevent calcium oxalate formation
- Monitor blood calcium levels:
- Regular bloodwork helps detect abnormalities before crystals form
- Encourage your dog to drink more:
- Provide access to multiple bowls of fresh water
- Use a pet fountain or add ice cubes for stimulation
- Offer wet food or moisten dry kibble
- Follow a veterinarian-recommended diet:
- Specialized food helps reduce crystal formation
- Do not change your dog’s diet without professional guidance
Important follow-up and screening
- Urinalysis:
- Checks urine pH and detects early signs of crystals
- Helps guide dietary and treatment adjustments
- Routine x-rays:
- Detect hidden or recurring stones in the bladder or kidneys
- Allow early intervention if needed
A proactive monitoring plan helps maintain your dog’s urinary health over the long term.
Consistent care for a healthier life
By following these prevention tips and staying in contact with your veterinarian, you can greatly reduce the risk of complications from calcium oxalates. Regular monitoring and hydration are key to protecting your dog’s urinary system.
