The thyroid and salivary glands are located in the dog’s neck area. Recently, concern has been raised that these organs might be injured when sharp pressure is applied to this area by a collar. The risk is thought to be particularly high in dogs who lunge and pull when on lead. While we have not identified any documented reports of injury in this manner, those who are concerned about thyroid and salivary gland damage, particularly those whose dogs have been diagnosed with hypothyroidism, might want to consider the use of a harness or ‘gentle leader’ instead of a collar when walking their dog.
Our Frankie has normal thyroid function, but can get excited and lunge when we encounter something exciting on our walks, as we did this morning when we flushed a flock of birds out of some high grass alongside the road. I think I just might switch him to a harness!
