My dog's nails are splitting. What supplements can strengthen them?

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Brittle nails or nails that split easily may be due to them being overgrown, due to nutritional imbalance, or certain diseases such as endocrine diseases like Cushing's disease. Certain autoimmune diseases like Lupoid Onychodystrophy can sometimes cause nails to become fragile and crack. I would make sure Chloe is eating a high quality commercial diet that contains fatty acids such as Omega 3 fatty acids and also vitamin E. I would also recommend having Chloe seen by her veterinarian for this as well to rule out any underlying disorders that could be contributing. Your veterinarian may recommend blood work or other diagnostics tests to help determine if any underlying cause is present. I hope this helps and thanks again for posting!

Thank you for submitting your question regarding Brando. I recommend that he sees his veterinarian. There are diseases that can leave the toe nails brittle. If he is healthy, then a fatty acid supplement may help. I hope this information helps!

This may be a resistant infection or the area may keep getting reinfected because it is in a highly mobile spot where contamination is very easy (the foot). I would recommend taking your dog back to the vet for a recheck and having her sedated for the examination. This way the doctor will be able to closely examine the toe and the nail. The doctor will then be able to clip the nails back far enough to hopefully remove the problem. There is also a specific disease of the toenails that may need long-term treatment from specific medications. This is an auto-immune disease, lipoid onchodystrophy, and has a very specific presentation. Your vet should be able to determine if your dog has this condition with a thorough exam. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Poor Ruger - I'm so sorry for his past difficulties as well as for what he's going through now - he's so lucky to have found you. The first thing I would want to rule out is ringworm in this location. I know it sounds strange, however it can get into the nailbed and cause the kind of brittle, discolored nails you're seeing. Ringworm is actually a fungus and not a worm as some people think. Your vet can run a fungal culture using shavings from the nails to check for this. If the culture comes back negative, I would probably next consider whether this could be a case of lupoid onychodystrophy. German Shepherds are predisposed to this disease, and since Ruger is a mix it's worth considering. Treatment can be challenging, but it's worth trying several things including omega-3 fatty acids, antibiotics such as doxycycline, and pentoxyfillne to increase blood flow to the region. Some dogs will also respond to steroid therapy. Best of luck getting this figured out.

If he walks on concrete or a hard surface then he may be wearing them down on his own, especially if the nails look normal. You could have your vet take a look at his nails if you are concerned there is a problem.

He could have allergies and/or a nail infection. He should be examined by a vet to diagnose and treat the problem. Your vet can prescribe an antibiotic, anti-histamine, and/or a corticosteroid to treat. You could also soak his paws in a warm Epsom salt solution and see if that helps.

Yes, I agree with your vet. Supplements often do more harm than good in these situations. If the fracture is a non-union/non-healing the supplement is not going to help. If you could post photos of the x-rays showing the fracture we may be able to help you better.
