Unlike cats, dogs tend to develop an underactive thyroid condition. The signs of this problem include decreased energy, loud snoring, a poor haircoat, the desire to be around heat and to avoid cold, and when advanced we can see breathing and walking problems. A simple blood test will reveal your dog’s thyroid level, and then we can assess if this level is normal for your dog or if it represents an illness. Treatment includes a yummy oral pill twice daily for life (and it is relative inexpensive!).
