Other Medical Conditions Connected with Licking Metal
There are a few other health problems that might be connected to this behavior. Dog health questions are always best asked of a veterinarian. These are more serious conditions and should never be treated without guidance from a vet.
Iron deficiency, or anemia, can happen due to hookworms. This is more common in pups but can affect older dogs as well. Animals will lick metal when they are trying to get iron into their bodies. A vet will treat this condition with wormer medication that kills the infestation and makes your dog healthy again.
Diabetes has also been linked to obsession-based licking. This disorder causes severe imbalances in blood sugar and can make a pet think that it needs iron to feel better. This health problem cannot be treated without a change in diet and diabetes medications.
Stomach tumors and Inflammatory Bowel Disease can also lead a dog to lick paint or something metal in the house. The connection to these conditions is less clear, but the behavior might be because these health problems often cause mineral deficiency.
Hyperthyroidism can also cause metal licking in dogs. This is also diagnosed with a blood test and then treated with adjustments to diet and medications. This problem may also lead to bad breath, so treating it with the help of a vet can make your dog’s breath significantly better.
