Bacterial Claw Infection in Dogs - Signs, Causes, Diagnosis, Treatment, Recovery, Management, Cost
What is Bacterial Claw Infection?
If your dog suffers from chronic bacterial claw infections, permanent defects to the claw can occur as well as hinder claw growth. If you do not properly treat the infection, more serious health issues such as a bone infection, or osteomyelitis, can arise. You may notice swelling in the nail bed area and pus formation when your dog is suffering from a bacterial claw infection. 
Dogs of any age and breed can develop a bacterial claw infection. If you suspect your dog is suffering from an infection of their claw, make an appointment with your veterinarian and have a proper diagnosis completed. Typical treatment includes oral or topical antibiotics, as well as pain control if needed.  
It is not uncommon for dogs to develop a bacterial claw infection. Often, this is considered to be a secondary problem that occurs after another condition has already developed. Trauma is the most common underlying cause of a bacterial claw infection in dogs. Other conditions or illnesses that can cause bacterial claw infections include diabetes mellitus, hyperadrenocorticism, hyperthyroidism, immune mediated diseases, hypersensitivities and onychodystrophy.

Symptoms of Bacterial Claw Infection in Dogs
If you notice your dog paying extra attention to one of their feet, take a few minutes to examine the affected foot. Carefully feel along the top of the foot and then closely examine the pad and between the toes. Also be sure to look closely at the claws, or nails, for any abnormalities. Have your veterinarian thoroughly check your dog over if you think there is a possible infection. 
Symptoms of a bacterial claw infection in dogs include:
  • Swollen nail bed
  • Pain in the foot
  • Limping
  • Pus coming out of the nail bed
  • Discolored claw
  • Soft claw
  • Brittle claw
Causes of Bacterial Claw Infection in Dogs
Bacterial infection of the claw can occur when your dog has a small cut or scrape near their claw and then they walk on ground that is contaminated with bacteria. They can also get a bacterial infection from chewing at their nails and having the bacteria transfer from their mouth to their claw bed. 
Keeping your dog’s feet, including their claws, clean and well trimmed to help keep them from picking up excessive bacteria and causing bacterial claw infections. If you are unsure of how to properly care for your dog’s feet and claws, speak with your veterinarian about proper foot care.
Diagnosis of Bacterial Claw Infection in Dogs
When you arrive for your veterinary appointment, you will be asked for your dog’s medical history and your veterinarian will perform a full physical examination. During the examination, your veterinarian will pay close attention to your dog’s foot pads and claws. If the initial examination shows that only one claw is affected, infection or trauma will be suspected. When more than one claw is affected, fungal disease, parasitic infections or nutritional imbalances may be suspected.
Your veterinarian might recommend additional tests to definitively diagnose a bacterial claw infection. These tests may include a complete blood count, biochemistry panel, claw bed scraping and bacterial and/or fungal culture. In more severe cases of bacterial claw infection radiographs and biopsies may be needed to determine the extent of damage caused by the bacterial infection and whether or not the infection has gone into the bone.
Treatment of Bacterial Claw Infection in Dogs
Once your veterinarian has diagnosed your dog with a bacterial claw infection, they will then discuss treatment options with you. Most treatments will include topical or oral antibiotic ointments and paw soaks. Paw soaks might include chlorhexidine or Epsom salts to draw any pus and reduce inflammation while promoting healing. 
If the bacterial infection has progressed beyond just the claw and claw bed, then your veterinarian will probably prescribe oral antibiotics for four to six weeks to ensure the bacterial infection has been resolved. 
Be sure to keep your dog’s affected foot clean and free of dirt or debris. Your veterinarian may recommend your dog wear a waterproof bootie on the affected foot when they go outside. The bootie will keep the affected claw clean and dry.

Thank you for your question. If the nail discoloration has happened recently, there may have been a trauma of some kind to the nail, and it would be a good idea to have a veterinarian take a look at him to make sure that he is okay. I hope that all goes well for him!

Thank you for your question. I apologize for the delay, this venue is not set up for urgent emails. I suspect something is going on with that nail that is making it so painful for her. She likely needs veterinary sedation and an examination to see what is causing this. It would be best to have your pet seen by a veterinarian, as they can examine them, see what might be going on, and get any testing or treatment taken care of that might be needed.

Thank you for your question. I'm sorry that is happening with your dog. It may be an infection, a tumor, or an injury. Without being able to see her, it is difficult for me to say. If you have tried treating it and it is not worked and it has been over a week, it would probably be best to have her seen by a veterinarian. They will be able to examine the area, see what might be going on, and let you know any recommendations for treatment. I hope that everything goes well.
