What nutrient deficiency causes pica in dogs?

Pica in dogs is usually caused by a deficiency of trace elements in the body, such as calcium, zinc, iron, and magnesium. If you suspect pica, take the dog to a veterinary clinic for a checkup.

If the pica is due to missing trace elements, supplement accordingly and promptly. However, pica is not necessarily caused by deficiency; it may also result from internal parasite infection, so treatment should target the specific underlying cause.
