Can dog food cause hair loss?

Graham says:

Food as the cause of hair loss is a question you have to be careful with. What’s most important to remember is that hair loss in a dog is unusual and something, if it happens, that requires a vet to look at it, regardless of the possible causes.

As to whether food can cause hair loss, well it is possible, but it’s very rare. So if your dog does start to lose hair, even if you think food may be the cause, you must immediately speak to your vet.

The most common causes of hair loss in dogs are actually:

  • Allergies
  • Infection
  • Infestation
  • Cushing’s Disease
  • Genetics
  • Pressure Sores

Where an allergic reaction causes the hair loss, then there is a small possibility that this could be from something in your dog’s food. But the possible causes are something you should discuss with your vet as there are probably more likely causes that need eliminating first.

When identifying the cause of the hair loss you will need to work with your vet through a process of elimination to determine precisely what your dog is allergic too. Once you have identified the cause, it should then be a case of managing this allergy. If the cause is their food or a particular food, managing the allergy will be based around no longer feeding your dog foods that contain the ingredients identified as problematic for them.
