Can dogs be allergic to their electronic collar?

Yes, dogs can be allergic to their electronic collars, though it is relatively uncommon. Allergic reactions may arise from materials used in the collar, such as plastics or metals, or from chemicals in the collar's manufacturing process. Signs of an allergy may include skin irritation, redness, or itching in the area where the collar contacts the skin. If you suspect an allergy, it's best to consult a veterinarian for advice and alternative options.
